How to Wire an AC Delco 3 Wire Alternator

delco alternator wiring diagram 2003 chevy

Can someone tell me where each wire goes. This wire probably runs to the starter solenoid, but it could also run directly to the battery positive terminal. The folks at Powermaster say to never test alternator functionality by removing a battery cable while the car is running. Both of these alternators generators can be wired differently depending on their application. Some guys go the extra mile and put a resistor in-parallel with the bulb, so the circuit still functions if the light bulb burns out, but I am too lazy to figure out which one, so I carry a spare bulb.

Wiring diagram for gm alternator

I've got a 3-wire from an early commodore in my '59 Belair. I have found its better to retain the sense wire to allow the battery to charge to its full potential around 14V. So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations. I stock the better ones and sleep well at night. I double checked my volt gauge with a multimeter and get the same 11. Just be sure to buy one with a lifetime warranty and keep the receipt because chances are that you'll need another one some time soon.

And they informed me that they did and this was an issue that gm had and there had been a safety recall on this. I don't recommend that you try this since you'll likely end up toasting your alternator. It has 3 wires, one large red wire from the back, and the plug coming out the side has one smaller red wire and one white. Now be sure to do this or once you start the car you cant turn it off without yanking out something , inline on this wire install a one-way resistor, like a zenor diode from Radio Shack so that current can only flow from the switch to the alt. We carefully traced the wires, as this regulator was originally wired into the horn relay, which acted as a power distribution point.

By connecting it at the the alternator, the battery voltage will only charge to 14v minus the voltage drop in the distribution wiring. In a derby you can't actually hear your own car running, so if you're not using an oil pressure gauge or voltmeter, this will tell you when your car has stalled. In this video i will show you how to re-wire your gm delco remy cs 130 or any newer cs alternator. With the belt installed and everything tight, we can install the charge wire on the back of the Powermaster alternator. You have substituted a volt meter for the idiot light.

With the proper brackets this alternator can be adapted to any vehicle or engine-powered equipment. Modern voltage regulators and self exciting regulators no longer need this ground function. Melted wire insulation and melted plastic from plug harness obvious short. This is the system voltage sensing used to control the regulator. Good luck and happy motoring.

Wiring this alternator is well within the capabilities of anyone with average mechanical skills. Most need the engine run full throttle to begin charging. Therefore, please contact Charlie's Repair and confirm the existence of any materials, design or specifications that are material to your purchase decision. It stops the alternator from back feeding the harness, and keeping the ignition circuit hot, with the key off.

Without further diagnosis, you would probably think you alternator is bad and be going to the auto parts store to get a new alternator, when in fact the one you own is perfectly good. The drain is about what a clock will draw. Was told by dealer it was a faulty I. Strictly speaking, the car should charge the battery with only this one wire connected. Sorry for diggin this thread up from beneath the grave.

This failure to excite the charge circuit is because of internal shortcuts in components and shoddy regulators. Never ever replace anything as important as a fuel pump with out double checking all connection and checking for voltage before putting it all back together. For what it's worth, my car is on its 4th alternator. I've used them before and had excellent service. I know I have hooked something up wrong but I can't figure out what? Essentially turning this into a 1-wire setup, thats not self exciting? You could have a bad supply wire from the Ignition switch or a Relay. As for the power wire for the ign switch it doesn't need a fuse, if your building your own harness you might try looking at a factory manual early 70's to get an idea of where they put fusible links.

On my 32 this is about. At high vehicle speeds with low electrical loads, the on time may be as little at 10%. The most recent incident occurred when the assistant service manager from the dealership took the truck out for a test drive for a total of 120 miles , and he reported that the truck never lost power. © 2012 Rick Muscoplat Save eautorepair. The wires and blower motor are suppose to be protected by a fuse but the fuse never blows. Without adding an aftermarket voltage sensor, the battery warning light will no longer be functional after removing the voltage regulator. Photos by Tommy Lee Byrd.

It's winter and I needed a defroster! If you have a amp meter or voltmeter in the vehicle. Hooked up the powermaster unit using the same exciter wire and boom 13. For derby purposes it isn't needed so it can be either left off or jumped over to the main power wire. Pushing on the accelerator made no change.
