CLICKING NOISE
#1
runninpony 
Hi Guys, now that my engine is running I can hear a clicking noise from inside the car. My AMP gauge was converted to a Voltmeter by Rocketman and my wiring harness was refurbished by midlife. So every time I hear the clicking, it's actually 1 click every 5 seconds or so, then the Voltmeter shows a drop but comes right back up. It sounds like one of the relays is the culprit, but I am not certain! What I'm certain about the clicking is coming from behind/under the dash! Any help is appreciated, as always! Thank You!!

Sounds almost like you have something grounding out and it's resetting the breakers over the glove box. Had that happen once when a toolbox slid into the taillight harness, cutting the wire and grounding out the positive.

Do you have rear defrost?  That can cycle on and off  at that interval.

Is it consistent.  Hot or cold, driving or idling?  Like Hemikiller said, can you tell where the sound is coming from?

Will it still do it with the car off but key in the run position so you can hear it better
If you need to leave the key in run for a while you might want to disconnect the wire to your coil and / or points

You can then start pulling fuses one at a time to try and find the circuit

I had a similar clicking noise that I thought was under the dash somewhere. Like you, I thought it sounded like a relay.

Turns out it was the clock in the console. Unplugged it and clicking noise is gone.

The clicking noise in my car was traced to the MIL; she talks non-stop and the teeth were clicking. Really annoying and no way to stop it, as there's no fuse to pull.

Let me check your shorts!

kcmash, It is at like an interval every few seconds. Hot, just got engine broken in. Clicking is coming from under/behind dash area. No defrost, it's a Convertible.

Don @ OMS, I haven't noticed any clicking sounds with the engine off and key in ON/RUN position. I will certainly check by pulling fuses one at a time as you suggested!

mbrew2, at this time my console clock isn't even installed just yet and fact is it was also rebuilt by Rocketman!
