i took the alt and got it tested and it is good. i brought it back home and hooked everything back up check all the wires and still nothing. the guy before i had it changed the wiring harness and im trying to make sure he didnt forget a wire. the alt has the two plugs and when the alt is hooked to the soleniod both plugs have power but its the power from the battery. i checked the battery with a voltmeter while the car is running and it is the same as before, around 12.5. does the same wire that gives the alt power, is that the same wire that charges the battery or is there another wire im missing, i can only find one that goes from the alt to the battery. i lost and really need to get this thing fixed. i have been called out by a srt4
You say the alternator was checked and it's good, so just for giggles, have you checked the fuses? Could be as simple as a blown fuse. If the fuses are OK, have you tried running a wire from the - post of the battery to the housing of the alternator. I have seen them have a bad ground and not charge. I would do the above before going to deep into the wiring. Then if those are OK, I'd check the voltage at the alterator terminal where the big wire connects. If it's OK, then you have a problem with the wire from the alternator that supplies the battery, via the solenoid post (maybe a fusible link or broken wire).
i dont think the wire is bad because when i unhook the wire from the solenoid the alt looses power so i know its getting from the battery to the alt but i dont know why its not charging. i ran a ground wire from the alt to the body just to be sure its grounded. how can you check to see if the alt is actually getting power. its shows power on both plugs but its just the battery power. does the alt get power and charge through the same wire??
