Battery not charging, no battery light HELP
« on: March 19, 2016, 08:28:32 PM »
I know i have this post somewhere else, but I want to start over again, the eagle sat all winter and now I'm back at it trying to get it to run again

Heres my issues

1.the battery won't charge, I removed the ALT, took it for a bench test, came back good.
2. Battery Light does not turn on with key on, (I don't think its blown, because it worked before, and then not work then work, ECT)
3. There are three wires on the ALT, the big red one to the battery, a small red one that goes to the same post the Big red wire goes, and a orange and black wire, that changes to a orange and white wire correct?


4. Starter questions, Is it normal for the car to not turn over, just hooked up with jumper cables? I didn't have a charged battery so i just hooked the posts up to jumper cables and jumped the solenoid and I could only hear the solenoid and the starter didn't run, Benched tested that, worked fine.

This wiring has kicked my  :censored: for 3 years now, I really want to drive this thing.

finally Im changing my battery cables over to 2 gauge, where in the world do I get a 2 gauge crimp connected crimped? I don't have a big enough crimper.

hi, I made my own 2awg batt cables last year. you can get the cable ends , in any style online, or even locally, I think I got mine from Fastenall. To crimp them, if you don't have the tool, find a local old school auto mechanic, or a small machine shop that has the tool. I got mine crimped by a buddy in the maint. dept on the job, so i was lucky to not have to buy the tool. good luck, gz

Bulb in the dash and/or the 10 ohm resistor in the on/off circuit of all GM 10si alternators. Main terminal needs to be live ALL the time the battery is hooked up. Ground cable to the engine block from the battery negative also needs to go to the frame/body and the battery posts/clamps must be clean and shiny (grey paste is lead oxide, which blocks power flow).

Test the 2 prong side field plug. One with be live all the time and read battery voltage. The other goes off/on with the key. You can hook a 194 bulb to a toggle switch across the 2 wires. With the key on, resistored power HAS to be at the second terminal. Straight 12V power without a resistor will feedback and keep the motor running. You can do a quick jumper with the light, which will come on and then go off when you rev the motor slightly. If it's right, it will charge until you shut the key off or too much power drain will shut the regulator off till you do it again.

I poked my self int he eye, spend the last few days blind and going to the eye doctor, so I'm back now lol

The two prong plug, the red wire is connected directly to the battery cable post, then the orange wire, is connected to the car,  Im supposed to have power on that orange wire as well? I thought in my AMC book it keeps telling me to ground the orange wire to see if the light lights up?

ok, let me see if I understand this I'm terrible at electrical things.

take a bulb, and connect it between the red and orange wire on the two prong plug? do I leave the orange wire going into the car, or do i totally disconnect it?

I almost need baby talk when it comes to me and wiring, I tried looking at my finances fathers 83 jeep with the 258, but someone redid that so nice, no wires like we have in the eagle, starter with solenoid on it, and only one wire going to it .

If you leave it hooked up and forget, it will drain the battery or it won't shut off. Probably burn out the internal voltage regulator after sitting an hour or so not running.

oh no i won't leave it hooked up, I'm was clarifying i just need to hook a bulb between the two wires, so the red wire and the orange wire? the one that hooks to battery voltage and the one that goes inside the dash? do I disconnect it from the wiring harness or do i just tap into the wires and jump them?
