Phil P 0 Posted January 21 Share Posted January 21 Hello all This truck belongs to a friend of mine and another friend of mine told him I could fix anything. Well to get started I need some information. The truck has an electrical problem in that the headlights will not turn off. Now before we get into a bunch of ideas as to why this is happing I need some basic information. Where is the circuit breaker / fuse panel? Where would I find the relays if this truck is equipped with relays for the heavy loads? Now just to inform you the driver advises that the headlights stay on even with the headlight switch removed.

hatcity 2,380 Posted January 21 Share Posted January 21 Crazy thought, but do they go out with the parking brake set? My truck was a 2001, and when you released the park brake, they came on Guy that bought it from me called one day about ready to tear dash apart Quote Success is only a stones throw away.................................................................for a Palestinian Link to post Share on other sites
tjc transport 1,216 Posted January 21 Share Posted January 21 agreed. a lot of these trucks came with daytime running lights. if the parking brake is off, the headlights are on. only thing that will turn them off is pulling the DRL relay.

Phil P 0 Posted January 21 Author Share Posted January 21 Hi A little more information. This truck has been owned and operated by the same person for several years. The headlight issue is of recent origin. Phil P Quote Link to post Share on other sites
Phil P 0 Posted January 25 Author Share Posted January 25 Hello All I have now found the fuse and relay panel. There were also several schematics in this location but nothing that gave me any information on the layout of the fuse / relay panel. Is there anyone here that has something that would tell me if one of these relays is for the headlights? Thanks Phil P Quote Link to post Share on other sites
