wayfarerstranger Posted June 22, 2012 Report Posted June 22, 2012 This could be any car but it is a 78 d100 last night my head lights, dash lights started fading in and out not off just dimming , radio keep cutting off & on to so it must be hot wired to the lights ... Has this happened to anyone else ? i haven`t looked into it yet but guessing the switch or a bad ground or connection some where ...any ideas would be appreciated . Quote
JerseyHarold Posted June 22, 2012 Report Posted June 22, 2012 Take a look at the bulkhead connector on the firewall. Quote
Plymouthy Adams Posted June 22, 2012 Report Posted June 22, 2012 test the ground on the firewall mounted regualtor..could also be a brush about to the end of its service life but I am betting that the regulator is going south..never seen one fail but have seen them do just what you described..

Dodgeb4ya Posted June 22, 2012 Report Posted June 22, 2012 As mentioned check the bulkhead connector and the wires at the back of the amp guage for over heating (nuts loose) if the truck has one. This same issue is very common on the B100-300 mid seventies dodge vans. Bob Quote
