82-88 tach fix
 

does anyone know how to fix the tach on a 82-88 Camaro?? I found the write up on the later style but im working on a 86:(

Re: 82-88 tach fix
 

did you read it?i used it to fix my 1989 tach.

Re: 82-88 tach fix
 

Yes; it will work on MOST model tach's.
I have fixed 3 various year model tach's.
I have an easier way though. When I get home i will take pics.
It involves tracing the wires from the Resistor-Pack to the edge of the board;
where there is MUCH more room to solder a resister.
Just clip the leads of the chip and trace the PCB-traces over to the side.
Scratch the coating off of the trace and solder correct resistor there.

tach board looks different for earlier models; but the same FIX works.

Re: 82-88 tach fix
 

excellent!! its off to the TV repair shop with my cluster..BUT!!! according to my FSM theres a" tach filter" if its bad .what are the symptoms? does anyone know the values? are they available from GM?:blah:

Re: 82-88 tach fix
 

Sorry, dont have a clue bout the filter.
All 3 of the ones i fixed were the same problem.
Resister pack
symptoms: tach pegs; or tach is wildly reading high
All 3 were the resistor in my case.
mike
BTW...all 3 were older tachs in my case.
one '89, and 2 '86

Re: 82-88 tach fix
 

I can sell you one i fixed for $45 + core. I do a professional job and I also replace the capacitors and carbon resistors that can cause a tach to malfunction.

thanks, Greg

Don't deal with Buloushie, This scum bag ripped me off. Hes going to take the money that he stole from me and buy a part from you. If he even pays you. This is fair warning for anyone dealing with this piece of sh*t.

Send me a pm if you need your tach repaired or text me 318-402-1244.

Thanks, Greg

Re: 82-88 tach fix
 

Are you still offering this repair?

Any members here have any feedback from past repairs?

Re: 82-88 tach fix
 

I have brand new circuit boards for 82-92 camaro tachometers. $50 shipped.

Re: 82-88 tach fix
 

You've created your own replacement board with new components?
Could you post a pic please? I'm sure several would be interested in seeing it.
Thanks

Here is the new one for an 82-89 camaro.

Re: 82-88 tach fix
 

Looks good! Hows the success rate?
Sending pm.

Re: 82-88 tach fix
 

I’ve sold about 900 and have only had one or two failures. Most likely due to an accidental short by the installer. I calibrate them on my test bench, but some may need slight adjustment. I build in a potentiometer for fine adjustment. It comes with alifetime warranty.

Re: 82-88 tach fix
 

gcj280, sent PM also :)

Re: 82-88 tach fix
 

Hi Greg, I installed the one you sent me, but had some questions.... PM’d ya ;)

Re: 82-88 tach fix

Re: 82-88 tach fix
 

Not to dig up an old thread but I'm having problems with my 83 Z28 tach. I have two clusters and both of them peg the tach if i plug in the white wire at the HEI coil. Original cluster was a mess so i ordered a used one off ebay and everything else works now. But same results with tach. Seller says tach was confirmed working.... Sounds like this is the fix. I checked out your website and the replacement boards look awesome. The car was originally cross fire, now carb 350 with HEI coil in cap distributor if that changes anything.

Re: 82-88 tach fix
 

Hi ShuffZ. Thanks! This is a very common problem with these tachometers unfortunately. My replacement circuit board should fix your tachs and they come with a lifetime warranty. I will give you a discount for 2 boards or we can work out a trade deal if you don't want both tachs. Just let me know. Give me a call or text when you are ready.

Thanks! Greg

Re: 82-88 tach fix
 

Hi, I've had trouble the rev counter, the other gauges jumping and live in the UK. Would you / do you ship to UK?

Re: 82-88 tach fix
 

Absolutely, I can ship USPS first class, but it takes about a month at least. If you want to pay a little more for shipping, I can do Priority International. (I prefer it btw)

Thanks! Greg

Re: 82-88 tach fix
 

For anyone who may be hesitating to pick up the Cajun Tach Shop board, don't.
Put one in my car, and am SUPER pleased to not only have my tach be correct for the first time since I've owned it in 13 years, but it was also dead accurate right out of the box.


@gcj280
Do you have any intentions of expanding to repairs/calibrations of other gauges on these cars or even others?

Re: 82-88 tach fix
 

Hi could you provide me with a quote for a board for my 1988 Camaro as I am in Australia, Melbourne.
Thanks
