Properly grounded?

My current wiring configuration has only one ground coming off the battery negative. It goes to the engine block. I notice there is what seems to be a small gauge wire that goes from the subframe onto the body of the car but it is broken. It is a pretty small gauge I would guess about 12 gauge or smaller. Looks to be old like maybe factory? Should I run a separate ground from the battery negative to the subframe and/or body of the car? All of my electrical works fine but I was just thinking that maybe it's not a bad idea? The only way I am grounded to the chassis is through the one large negative wire from the battery that is mounted to the engine block right now. Is that ok or???

Re: Properly grounded?

gound should be chassis to body

battery to engine
engine to chassis
more grounds the better off youll be.
if the motor isnt properly grounded you could get a leaking thermostat housing in the future.
I did because my engine wasnt properly grounded and caused corrosion to eat through the housing

Re: Properly grounded?

The original setup attached that pigtail wire from the neg battery terminal to the inner fender. It may look small, but it is the same size as the positive pigtail which runs from the battery, across the radiator support, to the alternator, regulator, and main input to the fusebox.

You should hook it up. Without it, the car is pulling ground from the motor any way it can, possibilities include through the shift linkage, clutch linkage, or "radio noise reduction" ground straps if installed.
