wildman Posted March 16, 2014 Share Posted March 16, 2014 I recently purchased a 1995 ch613 and I am having an issue with the head lights low beam works fine but the high beams will not come on even with the flash switch. The high beam indicator comes on on the dash but the lights themselves will not work have check the fuses and bulbs any help would be greatly appreciated thanks Quote Link to comment https://www.bigmacktrucks.com/topic/35051-high-beam-headlight-issues/ Share on other sites More sharing options...
MHfred Posted March 16, 2014 Share Posted March 16, 2014 Sounds to me like bad bulbs or bad connections since the indicator is coming on. Quote Link to comment https://www.bigmacktrucks.com/topic/35051-high-beam-headlight-issues/#findComment-237508 Share on other sites More sharing options...
RowdyRebel Posted March 16, 2014 Share Posted March 16, 2014 Who needs high beams? Only time mine are ever on is when I'm trying to tell the knucklehead coming at me to dim his. If you can't see at night, don't drive at night. Enough ranting for now, though. Make sure the wires are all intact. I had a marker light out...changed the bulb and it still didn't work. Turned out the wire was corroded and broken INSIDE the insulation, so it LOOKED good, despite not carrying power to the bulb. I didn't figure that out 'til I'd run another power wire up from a known good circuit and spliced into the wire not quite on the bulb side of the bad spot in the wire...at least then I knew the problem was in the last 6-8" before the bulb. Anyway, that's why I HATE electrical problems...can be anything, and you can't always see it. Quote When approaching a 4-way stop, the vehicle with the biggest tires has the right of way!

Td713001033 Posted March 16, 2014 Share Posted March 16, 2014 Wildman start by looking at the connector for the hood harness. from years of opening and closing the copper will actually break inside the insulation. you will have to feel for a flat spot or void under the insulation .

Freightrain Posted March 16, 2014 Share Posted March 16, 2014 Strange coincidence that both high beams are out? Had this happen to a friend. Only found out after changing the bright switch. Then checked for power at the plug and found lights were burnt. Doh. Quote Larry 1959 B61 Liv'n Large......................

Kansas farmer Posted March 19, 2014 Share Posted March 19, 2014 I've had this happen in older trucks and replacing the dimmer switch fixed the problem Quote Link to comment https://www.bigmacktrucks.com/topic/35051-high-beam-headlight-issues/#findComment-238164 Share on other sites More sharing options...
wildman Posted March 20, 2014 Author Share Posted March 20, 2014 I have narrowed the problem down to a short some where between the dimmer switch and the light sockets I would run a new wire but problem is I cant find a wiring schematic to tell me which wire in the dimmer switch/blinker cluster is the wire for the Hi beam any help would greatly appreciated Quote Link to comment https://www.bigmacktrucks.com/topic/35051-high-beam-headlight-issues/#findComment-238219 Share on other sites More sharing options...
