So are we saying everything is working as expected or that I should make changes? I’m still surprised there’s no direct connection between the alternator and battery. Seems like a long, complicated path of wiring to charge the battery.
Okay, my mind is blown. First, I deleted the ballast resister and cleaned up that ugly Union. Several wires are still connected, but I used a stud and ring terminals on each wire (crimped, soldered, and hear shrink).
At idle I got the following:
- Sniper screen: 12.5v
- Battery: 12.7v
-...
Sorry for the lengthy delay. Had some family in town and was much more eager to spend time with them than on the internet.
First, 1 Wild R/T I can’t thank you enough for the last part of your post. The internet (and forums specifically) are so full of judgement and hate, it’s refreshing to see...
Update time. Picked up a brand new regulator for a 1968, it looks exactly like the “1969 & earlier style” 1 Wild R/T posted. Removed the previous regulator, installed the new one. Wiring is as follows:
- 12V ignition into passenger side of the ballast resister
- driver’s side of ballast...
Thank you so much! I’ll report back when I have a new regulator in hand.
This car was restored over 20 years ago. I can’t imagine how the previous owner dealt with the lack of charging all that time.
A few extra / new notes.
Most important) I ran a wire straight from the battery to the alternator field terminal. Changing the engine RPM resulted in an increase in voltage. Around 3,500 rpm the voltage was around 15.5 volt and I let off. This tells me the alternator is good.
1) I verified...
Don, I did try both regulators (new and old). No difference in voltage output. I could try a third if you think that‘d be helpful. Are there any component tests I can do on the regulator to verify whether or not it’s functional?
Leo, I will give that a try. Two additional points I should have...
Hello everyone, new to the Mopar world and looking for some help on a ‘68 Roadrunner 383 that’s not charging. Sniper EFI screen shows 12.2 volts, dash gauge is dead center on the line between charge and discharge.
