OE Style Tachometer Issue

[NJBronk]

I’ve had the OE Style Tachometer since March 2023 and it’s worked flawlessly. The truck sat for a few weeks and I drove it today and the needle seems to be stuck under the pin (see pics below).

I contacted Tom’s and they’ve never seen this before…. Has anyone run into this?

I’m not sure if I can take the front off to manually move the needle…. I wanted to ask here before trying.

Ask your kid, you thought it has been sitting No, I've had the same gauge for several years and have never seen this.

Have you tried disconnecting it completely from the electrical yet? Including ground? Just to see if anything changes.

How much do you love this particular tach? Take it off the mount and smack it face down in the palm of your hand. If there’s any pressure from the needle against the stop pin, that should allow the needle to “hop” back into its proper position.
As in all things electrical/mechanical, your results may vary.

I have used it on speedometer needles that hopped over the upper peg way back when speedometer cables were hard wire in cars…def not in an EB though.

Are you currently doing 10,000 rpm, thats pegged hi.

The only logical way that could have happened is if the needle spun all the way around. As stated, disconnect from the electrical system and see if the pressure on the internals is released allowing the needle to spin back around to its normal resting place.

It wasn’t all the way around, the pics above are with power to it, then it drops down to 6:00 when the key is turned off.

I started trying to take it apart but I think the bezel is pressed on around the edge so there was no way to disassemble and access the face.

I drilled a small hole at “0” (which can’t be seen from the other side) and used a paper clip to lift the needle up over the pin. Turned the truck on and it seems to be working. I’ll check the rpm’s against my timing light when I get a chance.

Only downside is some small plastic shavings floating around and two small scratches on the silver part. Hopefully the plastic will work its way down to the bottom. Overall not too bad. If it bothers me or rpm’s are off I’ll just get a new one.

Clever solution. Hope it works fine.

May be able to take a vacuum (shop vac or maybe a keyboard vac) cleaner and suck the shavings out.
