Palmbchmonte Posted February 20, 2018 Share Posted February 20, 2018 In my opinion Yes. All of my classic cars have multiple grounds to motor and frame. I also ground my radiator. Quote Link to comment Share on other sites More sharing options...
Paul Bell Posted February 21, 2018 Share Posted February 21, 2018 Yes, it MUST be grounded to the body. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted February 21, 2018 Share Posted February 21, 2018 X2 Paul. I also ground the body to engine, engine to frame and frame to body. I call it "the triangle" never had an electrical problem after doing this. Quote Link to comment Share on other sites More sharing options...
Rob Peters Posted February 21, 2018 Share Posted February 21, 2018 Absolutely it should be connected to the fender. Without it you can see many different issues such as flickering lights. rob Quote Link to comment Share on other sites More sharing options...
rsorg Posted February 21, 2018 Author Share Posted February 21, 2018 thanks for the replies ,i do have the ground connected to the fender and my lights do flicker a little at night ,only when the door is open for the interior lights that are on.dome under dash, etc. not sure what that could be flickering, Quote Link to comment Share on other sites More sharing options...
Blackhawk Posted February 22, 2018 Share Posted February 22, 2018 Check all of your grounds, one may be rusty. There are quite a few thin grounds under the dash that are easy to break. Quote Link to comment Share on other sites More sharing options...
overdrive Posted February 22, 2018 Share Posted February 22, 2018 If there isn't one there already, it should have a toothed washer between the ring terminal on the wire and the fender. It will ensure a good connection. Dan Quote Link to comment Share on other sites More sharing options...
Leghome Posted February 22, 2018 Share Posted February 22, 2018 My 72 also had a ground washer between the headlight switch and dash next to the switch and a wire going to the body. Quote Link to comment Share on other sites More sharing options...
