Hi I have a 72 Monte Carlo custom I put the gas tank in last fall and was getting ready to start it and it just clicks,and then after a while no power, so I noticed the fender ground was missing so I added that, now the gauge cluster lights up again but there seems to be no ground to the starter as it won’t crank? We’re is the ground located for that. I also cleaned the ground from the battery to the alternator bracket so that isn’t the problem.
