When i turn on my headlights with the car running,the inside dash lights-speedo and gas guage-are dim,the turn signal arrows and high beam light are bright even though none of them are on, and my gas guage needle drops to empty. I have no extra wires hooked up anywhere. Before i did the engine swap 6 to 8cyl.all lights worked fine. I did change the alternator from a 37 to 60 amp-same wiring and same voltage regulator. Any ideas on why this is happening? Thanks JIm.

A good place to start is to check all of the grounds, under the hood as well as under the dash.

If you have no fear, you're not going as fast as you could.

is your new alt internally regulated? I'd look close at a diagram to make sure nothing else is diff from the six cyl. harness.

I had similar Problem on rewiring a 90RS it was a loose ground on one of the two plugs that plug into the back of the bezel in the dash. Good luck.

Check what you know is a new addition, The
alternator, Try Checking the ground, then removing one wire at a time, It does seem
as if you are getting some bleed through of
power, Make sure all connections are clean and take it one step at a time, Good luck.

I have a car with the same problem. Did you ever find out what the culprit was, and if so what was it? Thanks.
