Full Floater Posted July 9, 2015 Share Posted July 9, 2015 Hi. I have a 1979 RS600L. The headlight rocker switch will illuminate all the lights (clearance, markers etc) but not the headlights themselves. The lamps do in fact work as there is a momentary on switch on the dash that will light them up. Not sure if this is factory or not. But its only a momentary on... The dimmer switch has no effect on the main headlight rocker switch not lighting up the headlights..Where can I start looking? Id like to replace the relay, but im not sure where it is. Im new to the R model. Any thoughts would go a long ways...thanks!!!Kevin Quote Link to comment Share on other sites More sharing options...
Dirtymilkman Posted July 9, 2015 Share Posted July 9, 2015 Isn't there two switches on the dash? One will power everything but the headlights and the other will do the headlights and the outside clearance lights on the cab. Quote Link to comment Share on other sites More sharing options...
Full Floater Posted July 10, 2015 Author Share Posted July 10, 2015 Yeah you are right, there are two switches. They both light up everything that they are supposed to; except for the headlights. Quote Link to comment Share on other sites More sharing options...
Dirtymilkman Posted July 10, 2015 Share Posted July 10, 2015 There is a breaker for the headlights in the fuse panel. I'd switch it out with another. Could be a bad breaker. 1 Quote Link to comment Share on other sites More sharing options...
turckster Posted July 11, 2015 Share Posted July 11, 2015 There isn't a relay for the head lamps on that early of an R model, seems there is just a 10 amp breaker. The headlamp switch is where I would look at since it sends voltage to the dimmer switch when turned on. Quote Link to comment Share on other sites More sharing options...
Full Floater Posted July 12, 2015 Author Share Posted July 12, 2015 I replaced the switch today and it didn't do a thing unfortunately Quote Link to comment Share on other sites More sharing options...
