lights question

    Hey guys,

    Had a positive past two and a half days of plowing here in central jersey with thankfully, no problems. I was out this evening doing one more last minute job and just as I was heading out to the destination I notice my passanger side plow light is very dim. I check the connection, and wiggle it a bit and it gets dimmer, it would shut off then come back on or even both would go out as I would wiggle it. Meanwhile in the cab, I notice that the high beam indicator is on but not at the same brightness it usually would be even though my actual high beams were not on. The indicator would remain on when my truck lights were on, with or without my plow lights and go off when they were shut off. It would remain on if I had just plow lights on and no truck lights.

    Any ideas? Thanks

    been there done that

    the light that is dim has a bad ground

    use and ohm meter to check it out

    i'm 100 % sure of this

    because of the poor ground the dims draw ground from the high beam circuit. this cause a small curent which turns the high beam light on dimly. just replace or fix the ground and all should be good.

    Just be sure to remove the power from the component being ohm tested, or else you'll blow the meter!
