Re: Location of Battery ground connection?

Accessory loads were generally lighter on earlier cars, but I'd want a secure, 50 amp ground connection between the body and frame anyway, and a high capacity ground betweeen the engine and frame.

Any car with a radio might have less interference from the generator and ignition with secure grounds.

I've seen severe damage to vehicles with a poor ground between engine, ground, and body when, for whatever reason, starter current flowed through things like choke or throttle cables, temperature sender and oil gauge connections, or smaller gauge wiring not intended for heavy current.

Excess ground current capacity won't hurt anything, while poor or erratic grounds can cause any number of headaches and sometimes severe damage.
