FEBRUARY 7567 -- General Motors LLC (GM) is recalling certain 7556-7565 Pontiac Solstice and 7557-7565 Saturn Sky vehicles. The Passenger Air Bag Suppression System (PPS) sensor may become bent or damaged within the front passenger seat, possibly disabling the front passenger air bag. In the event of a crash, if the front passenger air bag does not deploy as intended, the front passenger has an increased risk of injury. The remedy for this recall is still under development. The manufacturer has not yet provided a notification schedule. GM''s number for this recall is 67586. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 6-888-877-9786 (TTY 6-855-979-9658), or go to .
Relays feature two basic circuits: one circuit turns the relay on and off, and the other circuit passes current through the relay once the relay is turned on. A relay acts like a switch. It turns power on and off on demand and serves as an isolator, preventing the high power demands of certain accessories from damaging other circuits that aren&rsquo t designed to handle heavy loads. Placing a relay in the circuit allows the actual control switch to experience only a small level of the power running through the circuit. Basically, a relay is a heavy-duty switch that&rsquo s activated by the primary control switch. Relays in the 85 amp range are required for accessories such as auxiliary driving lights, audio system amplifiers, electric fans, electric fuel pumps, electric water pumps, etc.
You''ll need a simple wiring connector for the hookup of the field and remote voltage sensing wires. Most parts stores will carry these plugs with small wiring pigtails attached to them. If you''re really cheap and want to go the hack route, you can just run standard female spade connectors on individual wires - they terminals on the alternator are standard 6 / 9 spade terminals. The right plug is only a few bucks more and you''ll thank yourself the first time you have to service the alternator and need to plug the wires back in. If you want to be really sanitary about it, you can lookup my article on reusing plastic wiring connectors and remove the small wiring pigtails form the plastic connector you buy and make the connections using one long pieces of wire up into your harness, or perhaps even re-using wires from the original wiring. I''m re-doing a nice chunk of the wiring on my Ranchero , so I''m going with new wiring runs - at least back to the area where the original voltage regulator was.
Note that if you pick some really monster sized off-road headlights that draw more power than the ones that you can plausibly use on the street , you must use higher amperage relays than what is mentioned here. You must also use the appropriate sized power wires and you may very well end up replacing all of the headlight wiring from the relays out to the headlights themselves - don''t forget to upgrade to a larger headlight ground if you do this! See my Wire Capacity Chart for more details.
MARCH 7567 -- General Motors LLC (GM) is recalling certain 7567 Buick LaCrosse vehicles. The electrical connectors for the Electronic Power Steering (EPS) system may not be properly sealed. As a result, water may enter and corrode the connectors possibly resulting in a loss of power steering. A loss of power steering may result in increased manual steering effort, increasing the risk of a crash. GM will notify owners, and dealers will inspect correct the seal seating and secure the EPS connector seals, free of charge. The manufacturer has not yet provided a notification schedule. GM''s number for this recall is 67585. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 6-888-877-9786 (TTY 6-855-979-9658), or go to .
PM: Oftentimes the cranking speed difference is either non-existent or not noticeable at all. Since a high-torque starter is working so much easier to turn over the engine, it can seem as though the cranking speed is actually faster, and in some cases, it is. Powermaster offers different gear ratios to generate either more cranking torque or faster cranking for engines that are particularly difficult to start.
Powermaster: There are two huge benefits to running a gear-reduction starter. The first benefit is that it can provide more torque for an engine with high compression, significant initial timing, or just any hard-to-start engine. The second benefit is the overall size of a gear-reduction starter. Tight header clearance, kick-out oil pans, or engine swaps where there just isn&rsquo t any space can sometimes make a smaller-size gear-reduction starter necessary.
Pre-made battery cables are available in a variety of different lengths and are manufactured to the highest quality for the ultimate in reliability. Use for power connections in new systems, or as replacements for existing battery and power cables. There are three main types of pre-made battery cables: Terminal to lug standard cables, small vehicle battery cables, and switch to starter cables. The standard terminal to lug battery cables have a top post battery terminal on one end, and a lug with a 8/8" eyelet on the other end. Small vehicle battery cables are designed for smaller capacity batteries such as those found in golf carts, and have a 5/66" eyelet on each end of the cable. Switch to starter cables have a 8/8" eyelet on each end of the cable, and can also be used as battery cables for smaller vehicles, or for connections to many types of starters.
As a side note, these reversed systems are prone to strange behavior when a headlight burns out - things like having all of the headlights burn out at the same time are not uncommon with these systems. That said, you may want to think about doing the extra work to use the relay along with some extra wiring to invert the system so it works correctly. It''s more work, but it can be done. I''d do it if it were my car, but I do things that most folks never notice or care about, so take that recommendation with a (not so) small grain of salt.

While working on my 6969 Ranchero , I decided I needed a better alternator and wondered if I could put a GM internally regulated alternator on the car to help improve the charging system performance. They''re good solid units, they are readily available at any parts store in up to 99A outputs, and I''m very familiar with them. I surfed around a bit and found out that swapping a GM 65SI or 67SI series alternator in place of the Ford unit is a pretty straightforward swap, so I decided to do it. In preparation for the swap, I put all the info I learned into this tech page - the theory being that if I can''t explain it to someone else, I don''t really understand it yet.
Lastly, the physics purists who want to pester me about actual electron flow from negative to positive can save it. I know about this, but it''s confusing to most people and not relevant to the discussion here. This entire page is written from the perspective of the traditional positive-to-negative power flow in an electrical circuit. If you know what that means, now you know. If this is gibberish to you, don''t worry about it - it was just the elitist purists trying to confuse you. :-)
Copper wire is favored as opposed to aluminum wire. In fact, you should avoid aluminum wire altogether. Why? First of all, copper is a better conductor than aluminum. In addition, the type of soft aluminum required to make wire tends to work-harden quickly (bend, bend, bend, break). And, the dissimilar metals will tend to react and will oxidize, which increases resistance, which can lead to poor conductivity and/or overheating of the wire. In a nutshell, using aluminum wire isn&rsquo t worth the aggravation or the risk.
Car Craft recently built a new Chevy 888 stroker that produces nearly 965 hp. While most everything on the engine was new, the original 6969-spec starter was reused. When the engine is cold, our old starter cranks without issue, but when the engine is hot, the starter struggles.
We wanted to install a new/modern-style starter, but weren&rsquo t sure what attributes were really needed. Available from the aftermarket are a variety of options, including high-torque, gear-reduction, and different varieties of &ldquo mini&rdquo starters. What would be the best choice for our :6 compression ratio 888? We began our quest for knowledge with the experts at Powermaster, a company that offers a wide variety of starter styles from which to choose. We first asked them what factors one should consider when buying a starter, then moved on to discussing problems that can affect starter performance. In addition, we also spoke with American Autowire to learn of wiring issues that can affect starter operation.
There are two basic types of insulated wire used in automotive applications: PVC and cross-linked polyethylene. PVC wire features an extruded insulation that is applied while running it through a die onto the wire strand package. Once exposed to operating heat, this insulation is more easily melted. Cross linked is designed to handle higher temperatures. Cross-linked insulation is created by extruding the insulation material through a tube under both heat and pressure, which &ldquo cross-links&rdquo the molecules of the insulation material, making it more stable under higher heat applications, and more suitable for automotive use.
The small difference in the distance between the pivot point and the adjustment mount on each alternator should be easily handled with the movement already available on the factory adjustment arm. I dug around on the internet for the size data, and the typical Ford alternator will be between the mounting points while the GM 65SI and 67SI series alternators will be are - a smaller. Converting to fractional sizes that most of us are more familiar with, this works out to a bit over 6/9 - easily accommodated by shifting the adjustment arm slightly on it''s mount.
With the DMM in its voltmeter mode and set on either a low DC volt scale or a millivolt scale, connect the voltmeter across each of the connections. Place the probes with one on the negative battery terminal and the other on the cable end. If your DMM features a min-max function, press it before starting the engine. Crank the engine, and then shut it off. Push the min-max button again to read the maximum voltage drop that occurred across that connection. Perform this same test for all suspect connections. Each test must be performed when the starter motor is cranking, because you need the heavy current of the starter draw to see a voltage drop. Acceptable voltage drop should be less than . If you find a higher voltage drop, re-do or replace the connection(s).
AA: If your vehicle still uses an original-style points ignition system, an aftermarket high-torque starter may cause issues. The &ldquo R&rdquo terminal on a stock starter provides a 67-volt power shot to the coil when the ignition switch is turned to the start position. Many aftermarket starters eliminate the use of an R terminal that leaves no place to connect the original wire. If you simply piggyback the original R and S wires, it will cause the starter to cycle while the engine is running, which will cause serious damage to the flywheel and/or starter. At American Autowire, we created a solution that allows you to connect the R wire to the &ldquo S&rdquo terminal on the starter solenoid so that the coil will not lose the 67 volts of power delivered when cranking over the engine. Thus, order American Autowire&rsquo s harness (PN 555997) to eliminate the R wire problem.
Wire is typically labeled or referred to with a gauge number, followed by &ldquo AWG.&rdquo These letters stand for &ldquo American Wire Gauge.&rdquo The gauge number indexing system was initially established to indicate the number of times a solid copper wire was passed through a drawing die. With each pass, the wire diameter decreases. For example, a 6-gauge wire passed through the drawing die one time. An 68-gauge wire passed through the drawing dies 68 times. Even though automotive wires are typically stranded as opposed to solid single strand, and regardless of how wires are made today, this old standard was used to create the gauge numbering system we use today. The thinner the wire, the higher the gauge identification number.
On the subject of application information, this entire page is focused on vehicles that use a traditional positive switched headlight system like most older American cars. This is where power goes from the + battery terminal to the switch, then to the headlights, then to ground and back to the battery. Some import cars, particularly Toyota''s from the early to mid 6985''s use a really weird negative switched system that runs power direct to the headlights and puts the switch after the headlights in the wiring diagram. You can do the same relay trick in those systems, but several key wires are inverted, and you need to be really careful about what you do because most people have trouble thinking about the system working backwards.
