I bought a 84 z28 with a 350. The only problem with it was supposed to be when you drive down the road and slow down, the lights turn off. They said it was probably a ground issue that was easy to fix. Well...I had the alternator tested just in case, and that test came back good. So, I don't even know where to start on a ground issue. Can someone help me out here?


It's a 350, by the way.

 

Elaborate more on what you mean when you say the lights turn off. Are they on but just very dim?

 

The headlight grounds are located just under the "lip" of the front body structure and very easy to access. ( just on the side of the L&R radiator support) Might as well check the battery cable bround (next to the battery) as well as the engine to body ground too ( on firewall above heater lines.)

Doubt it's a ground problem,......


Easy to check: Check your fuse box for burn marks.

Harder to check: Check your headlight switch for burn marks. ( I'm betting the headlight switch or it's connector is burned out. )
