Just checked the wiring colors....
Everything seems to be OK....though the diagram shows the firewall connectors upside down compared to what they are on the car...LOL
The car runs and the gauges etc work fine, so I think you are right.....gotta be an lt or vr issue....
I guess I will pull them both and take a trip down to autozone tomorrow....assuming they are open.
I just had the alt off the other night when I was installing the new heater hose brace.....
Could a bad ground on the VR where it mounts to the firewall cause this?
Scratch that....just realized I have a ground strap from the VR to the valvle cover bolt...so ground should be OK.
Whats strange is I ran like this all summer.....shouldnt I have toasted the battery by now???
If I have the green/purple wires at the alternator swapped (both go to the VR) would that cause this? No, right? You posted an answer to a similar question here...http://www.cuda-challenger.com/cc/index.php?topic=43800.0
which is how I wired mine....green wire in the center connector.
Well, I guess that pretty much rules out the obvious stuff......I have the original VR that was in the car when I got it...no idea if it is good or not....may try swapping it in just to see....see any harm in that?
