Headlights flicker- relays chatter

Recommended Posts

Need some help and direction. Headlights flicker sometimes over bumps. Found that if I tap on my relays with the lights on the lights flicker and the relays chatter. This is a 71 which I upgraded to relays . Oddly I have my fuel pump on a relay also and I can get it to chatter also by tapping it. Only thing I think they share in common is the power source. The main power comes from a power strip that I have connected directly to the back of the alternator . Pretty sure the grounds are different between the headlights and fuel pump. 

Appreciate any testing methods

Problem solved 99% sure. So I pulled the relays off the sockets to remove sockets and install new grounds. Then I noticed the trigger wires on the headlight relays about falling out of the sockets. These were part of a kit and I installed all the wiring. So I guess I didn't get the trigger wire pushed in until the spade catch caught on the socket. Pushing on my relays caused them to about fall off, so I was having a weak trigger signal . Must of been like this for years , but just now really started acting up. Now I can bang on the relays and nothing happens
