Headlight issue......a bit different this one...

Ok, I had an auto electrician fit relays to my headlights to relieve the switch and it's issues...but, now I have another problem....when I turn the lights on, to park, the low beam comes on, and so do both indicator arrows in the dash display....after a few minutes, they indicator arrows go off, and the truck drops to park. If I put the lights directly onto low beam, then high beam comes on too....regardless of the dip switch position...and the indicator lights too.....any ideas, any idea of a fix...I will be taking it back to the electrician, as I am not happy...but if anyone has any tips, let's have 'em!!
They were working fine before it went in, apart from the "usual" flashing/cutting in and out.
Truck is a 1977 F150 Ranger XLT.
Thanks,
Shane

I would recommend taking out what was done and redoing it.



Bascially you take the old passenger headlight socket and use that to trigger the relays and then run new headlight socket wires to each headlight.

Add a new power wire with fuse to each relay.

Done.

Now the old headlight switch and dimmer switch are only being used to activate the relays.

The advantage is the old wiring in these vehicles was designed to power the old style headlights and with the newer style halogen bulbs installed the current draw is almost beyond the capacity of the wiring. You lose brightness with the newer bulbs. Installing the relays allows for the old wiring to be used only as a trigger for the relays and you get brighter headlights. I acquired a harness, pre-made, and installed it in my truck some years ago and have been pleased with the results. I had heard some bad stories about the relays burning out in this harness so I went out and purchased a couple of replacements and put them in my 'go' box just in case. Never have needed them yet. Here is a link to the harness I used, plug and play. LMC Truck Parts - Page 137

Even if you use the old headlights, the advantage is you take the amp draw off the headlight switch which is the weak link in the system and especially if you pull a trailer (extra lights) they burn up and even over heat the harness connector. This eliminates this problem.
The other advantage even with stock lights they are brighter because they get full battery voltage instead of loosing voltage from the lenght and smallwires for the headlight system that is stock.

Issue fixed

Well, looks like it is sorted, the sparky tracked it to a faulty earth in the dash wiring....it only takes a sniff of power to trigger a relay.....so there ya have it, the old wiring was causing the issue!!
I agree with the above comments, it is well worth getting the headlights relayed, they are far brighter, and it protecs the trucks wiring and switch too

or if you have as much time on your hands as I do, build your own harness set, I'm in the process of doing just that.

Been there. There's not a lot to do in Cheyenne in the winter. Lived a lot of years in No. Utah, kinda wish I was back out west.
