Nope bought all new CAR battery wire and a new starter. Also picked up a 1000 cranking amp battery. AAAnd going to wire a ground from the starter relay to the engine block to the frame.
Starter relay isn't a ground point, it uses a ground to close the relay when key is is "start" position but not alot of amps there.
Battery "-" should be connected to the engine block, and then from there to the frame with the same size(gauge) wire.
You can add another ground wire from block ground to one of the Starter mounting bolts, again same size(gauge) of wire, this should give the starter a better ground point.
Battery "-" also needs smaller wire to Radiator support bracket for the head lights, and to the fender/body .
And engine should have a ground strap from head to the firewall.
