Re: Polarity reversal

When I got my '55 Caribbean the ground was backwards (see post). It ran fine with a neg. ground and everything worked great except the amp meter. When the lights went on it showed "Charge" and when it was rev'd up it showed "Discharge". At the time I assumed the meter was wired backwards until I read "Positive Ground".

When I discovered it, I switched back to a pos. ground and there were no issues. The amp meter now worked as it should. Then I wanted to update the radio while keeping the original look. I opt'd for radio from Aurora Designs which required a neg. ground to avoid additional cost(see post).

I have not switched the polarity on the amp meter because I don't want to take any changes with messing the wiring up by digging around in a tight space.
