Negative or positive ground system?


Unregistered guest
I'd like to know if my Buick Roadmaster is a negative ground or positive ground system.

I'd like to buy a cell phone charger, but it is only for negative ground systems. How do I determine that?

it's negative ground.

positive ground systems are very rare.
I don't think anything GM has made in the last 50 years has been positive ground.
