head lights

[Cratos]

Well I had the Grinch out at night for the first time ,and the darn head lights would just go out and then come back on a min later!! all wiring is new as is everything else switch was supposedly gone through when the dash was sent out and reconditioned. Also when I hit the brakes the light flicker once.

Any ideas? ( if it’s not one dam thing it’s another!!!

It is likely a grounding problem. Wires grounded to painted surfaces may not make good contact. Start there.

I would upgrade to relays for the headlights all modern cars use relays , no point in putting all of the current through the headlight switch & the bulkhead twice . WHich light flickers when you hit the brakes ?

Very much agree!

I have the kit, just not time to put it in yet.

....and pack your bulkhead connectors with die-electic grease like Chryco recommends....
Cured all my gremlins but still hook up the headlight relays...!

I did that when I installed the new wiring harnesses. during the overhaul.

If you get active action on unrelated circuits, that sounds like ground hunting.

Was that on high or low beam

 

[Cratos]

installed your harness to day No low beams but both hi & low on hi and checking that there is No power into the low beam relay? checked fuse and swapped relays still No power coming into the low beam fuse.

 

[AUSTA]

Also check the floor low/high beam switch the centre should be positive mine wasn't making would lose lights after a few minutes

 

[Cratos]

brand new one today no power coming into the LB fuse holder

 

[crackedback]

Sent you a PM. I bet I solved it in the PM...

Won't have anything to do with the OEM side of the system.

This! Had the same problem and replacing the floor low/high beam switch fixed it.

yep replaced it, while I was working my way through this.

when any pre 78 car came in with the problem described all we would do is replace an aftermarket dimmer switch with a genuine 1881938 switch
