Technical 1941 Lincoln

My buddy had a customer bring a non- running car to his shop. A 1941 Lincoln Conv. V-12. He got the engine straightened out. He was in the middle of buttoning things up and noticed that although it was a 6-V system. It was wired NEG ground. The repair manual the owner has, doesn't really say. It just shows a group of lines for the battery in the wiring diagram. I think we deducted, the short line is NEG and the long line is POS. If so, NEG ground is right. It just seems wrong. Any thoughts from you guy's??? Thanks, Gene.

 

My Motors Manual says all Lincoln V12 cars are Negative ground.

 

wow....interesting....very interesting..........

 

Crawl under and follow the wires back. Ground will go to something on the chassis. Positive May go to the starter.
My wife’s 33 is wired this way. Ground to the transmission. Positive to the starter.

 

I think the ground goes tho the + Of the battery

 

Thanks for the replies...we were thinking NEG ground. But it went against what we thought we knew. Gene. OH, and Happy Easter....
