Hi all,
I bought a 1967 250SL, that had been in storage for years. The battery in the car was disconnected, but the red wire going to the battery (by the + terminal) is grounded on the chassis, and the black wire goes off toward the engine and starter. It looks like this car (a Euro version) has a positive ground. I did a search and found a thread that says all pagodas are negative ground. So now I'm completely confused,,,
