I have a "tick, tick, tick, etc." in my dash when idling and running. When I get up to speed, the noise of the car drowns out the ticking, but the noise does increase in pace as I rev the engine or drive. I have no clue what it is. Would the tach create a noise like that? (The only thing I can think of, but I've never heard a tach before.)
Thanks,

Maybe speedo cable?? I know that my needle wiggles because i havent greased the cable in forever.

 

I'm pretty sure it's not the speedo cable..... I hear the ticking when it's at idle.

 

does your ashtray have both screws in it. when i took my bezzle off for the radio it would wiggle and make a ticking noise. or it may be your tach cable?? does your tach whine?

 

I hear a ticking noise in my dash when the stock fuel pump kicks off when I'm trying to start it. Maybe yours is malfunctioning and is ticking uncontrolably!?!?! IDK.

 

IDK either about the fuel pump either, but it's worth a look. The tach doesn't exactly whine, but it could be tied to the tach because the ticking is related to engine speed. My questions linger, but it doesn't seem to be affecting the way the car runs, so it probably won't see much attention until it does. I would, however like to solve it. Any other thoughts would be appreciated.

Have you checked your fuse box? I had a similar ticking sound while my car was running that turned out to be a loose wire in the fuse box that was causing an arc between the fuse and the contact.

 

Not yet, but thanks. I will. Good thought. It sounds like it's coming from higher up and more to the middle than the fuse box, but I will check it anyway. Appreciate it!

 

I hane an 85 12a and is also doing the tick tick some where in the dash on the driver's side. Hellllllllllllllllpppppppppppppppppppp!

 

thats for sure a speedo or tach cable. does it increase with speed or rpm.

 

No. It only does it at idle, as soon as I give some gas it stops.

 

its eather a loose screw or your tach cable. lay on the floor looking up with the car on and see if you can see somthing or spot the sorce ot the sound. but I'm guessing tach cable
