1970 Satellite headlight problem

[GTX clone]

Headlghts flicker on and off on high beam only. Switch to low beam and they work fine. Ive cleaned the wiring harness mounted on the firewall, seemed a bit better for a while, but still doing it. Headlight switch on dash feels warm, not sure if that is normal?

Is the ground up front ok? Mine was about done when I took a look at it. It was on the radiator mount to a bolt where the wiring passes through. That switch may also be going bad.

I am converting my 70RR to relays and H4/H1 lights. Maybe take a look at doing that also, or doing the relay setup so you can off load the power from the switch to the battery.

I have the ground going straight to the battery now, and still the same problem. The high beams come on and stay on for about a minute or two, and then start flickering on and off, so I'm leaning towards a circuit breaker maybe? any idea if there is one on this car and if so, where is it located?

Hrm.. sounds like the switch. I am not aware of a circuit breaker in these cars... fuse yeah, but not circuit breaker.

Ok, maybe I'll try the switch. Thnx

Yeah.....look at the switch on the floor. It's either fried or a wire is loose down there.

 

[dasol7172]

Oh yeah.. floor switch. Check that for corrosion and the connections. I was thinking the dash switch.

Check those wires and terminals - I've seen those melted before.

Checked ALL wiring, on both the dimmer switch, and also the headlight switch on the dash. All the wiring looks good. The dash switch is getting very hot! So hot u can hardly touch it. If you keep it on dim, it doesn't heat up. Only on high beam. I unplugged the wiring harness from the back of the dash switch and run a jumper wire across the bottom to the top post. Lights work on high beam without cutting out, but the wire harness gets pretty hot. I'm guessing that switch shouldn't be getting that hot, and that's why it's cutting my lights out after about a minute or so?

You may want to pull that dash switch and make sure its not got some melted parts on it.

I would go the relay route also. Found this diagram to give you an idea. Its from http://www.rowand.net/Shop/Tech/images/HeadlightRelayWiringDiagram.jpg

Yeah, internal corrosion on the headlight switch will cause a high resistance in the circuit, which will make it heat up. Change it out now. Also consider doing the remote relay conversion and read the Mad Electric article. http://www.madelectrical.com/electricaltech/amp-gauges2.shtml

Ok, thnx. ill give it a try!
