Just moved dash and all wires out of a 100% working (electrics, that is) '71 Cutty to a '72 Cutty. Everything works except the high beams and the left side turn indicator. I've made sure the wires are solid, and I've tried exchanging bulbs - no problem there. Moved the high-beam wires to the other set of headlights, resulting in them working, but I can only ever get one set of headlights to work, namely the set with the high-beam wires on them.

Question: do the brights work on a different ground connection than the low beams? The horn works as well, so I assume that my front clip is properly grounded. The right indicator and both front bumper lights work.

Furthermore, I have a male dual-connector with an orange and a pink wire dangling from under the steering column, but nothing in sight to plug it up to. The '72 dash I have has the same plug, also unplugged, so no help to be had from that.

Does the dimmer switch on the floor feel strange or different when pushing on it?
Sometimes they can be cleaned, but replacement isn't expensive!

Seff

I have a spare, but this one switches between no light and whatever set of lights I have the high-beam wires connected to, so I'd hazard the guess that it works like it should.

The orange and pink wire connector os for the TH400 downshift switch. If you have a TH350 tranny, it just hangs there.

Seff

I do indeed have a TH350, so that's one thing eliminated. I'm checking fuses again tomorrow.

You should try your new dimmer switch and check the connections at the dimmer switch connector. Sounds like the bulbs are working by how you described it. Both beams use the same ground wire.

Seff

Hrm, I will. I'll come crying again if it doesn't solve the problem.

It works, except that the left blinker is on all the time like the front bumper blinker, while the right one only blinks when the blinker arm is actuated. Someone was creative with this wiring.

Blinkers have nothing to do with headlights.
Check both front and rear bulbs for correct insertion and grounds.
I once had a problem with sand, [from sandblasting] in a socket with that 'grease' in it! Once clean - worked perfect!

Seff

You're right, but as I said, I had problems with both the headlight and the left blinker. Both problems have been identified by now.
