I am working on a 73 Challenger and cannot figure out why it is not charging. Hoping someone can help. It has a 340. New enging wiring harness, voltage regulator, battery and the alternator has been tested by a shop and said to be good. Any ideas?
yea, it's been quite a while since I did this stuffIt is a 3 wire alternator. The main output and 2 field wires from the vr . One has ignition power with the key.
yes it is - - at the ALT side in the physical mounting, not wiredThere is no case ground.
that's the idea, but the 2-wire from the VR is iffy.How do I full field that one. Same way? Pull the non powered field and ground the terminal it came from?
grrr, that would FRY everything in the car; charging voltage should not be more than 14.7v. 22v sounds like the coils internally are not correct.Something else I find strange is the power out of the alt is 22 volts but yet I have 11.2 at the battery and other power sources.
Could it be the amp gauge in the dash causing it?
