another light problem

Okay so when i turn my head lights on the lights flicker and there is a clicking sound from the light switch. I can't figure out if the regulator in the switch is bad or if i have a short some where. this is in my 65 comet. by the way it just started randomly. and my alternator is working.
Please help me pin point the problem thanks.

Comet Boy,

Check the trunk. The wires for the running/parking lights can get smashed by a heavy load being hauled and cause a short. Also if you have installed speakers or something near the driverside rocker pannels you might have installed one of the screws right into the running/parking lights wire causing a short also.

Good Luck

same issue kinda

i have a 66 comet and kinda have same issue.

when i turn on headlights after starting the car, they flicker a bit. When I step on the accelerator a little..the lights get brighter (this also includes interior lights getting brighter too). I dunno what it is. Loose belt on alternator? bad alternator? all wire connections are tight i think. Only after devices connected directly to the battery are a aftermarket stereo and remote keyless entry.

Hope u figured out your problem, cuz i'd like to solve mine as well.

Doc here,

On your Comet, check the output of the alternator.

Measure at the battery with a DMM set for V x 50 scale, it should read no lower than 13,75 volts..preferably 14.4 volts..

Headlights will dropout, or severely Dim at about 10 to 11 volts..If while revving the car, it pops up to 14.4..then you have a bad regulator..

If it doesn't come up, you may have a bad rectifier diode pack on the alternator..(one or more diodes bad..)

Or if it does not you may have bad grounds..If that is the case do this:

Run the main battery ground at or near the starter to any handy block bolt.

Add to that a battery cable with 3/8 ths ring terminals on BOTH ends (auto parts or wally mart..about $6 bucks for 3 feet..)

Ground the OTHER end to the frame wherever handy..

Back to the block bolt,

Run 2 10 gauge wires from there , one to the firewall, one to the alternator mount bolt or ground lug..

Next get some ground braid..(radio shack or auto parts store) run your braid as follows, one from the fenderwells to the frame, the radiator support to the frame, the doors to the door posts, hood to firewall, Trunk to body, gas flap to body.

Burnish ALL ground points free of paint, oil and dirt. Use a proper star washer and lock washer, and you can use tech screws (self drillers ) where no screws exist to bond to.


Check the headlight switch to see if it isn't mechanically defective..(shake the knob with them on..)

Also on Fords (and I AM NOT A FORD GUY...) I believe they put a thermal link on the switch (circuit breaker) That may be defective, or loose, as well as the plug on the switch..You can also as said have an intermittent short on the harness wires shutting down the breaker and reseting it..(Clicking)
