I just replaced my worn out ground cable and was wondering where would be the best place to put the ground cable. I see most people ground their cars on the alternator bracket. Does the alternator require the ground? There is also a secondary ground wire that comes off the cable that was originally attached to the firewall. Can I attach the primary ground cable to the subframe? I used a wire wheel and cleaned off the frame surface to expose fresh metal and attached ground to a bolt. Now I think of it, the cable will be a pain to replace once my front clip is back on. Is accessibility the reason its out on the bracket or does it ground the alternator and chassis?
