Re: tach doesnt work...

The tach problem is caused by a Resistor going bad. There is a really helpful thread about it here;

Re: 89' Iroc 350TPI 700R4 Problems

no, teh tach issue is a resistor thing and has nothing to do with it. I've been driving around with my tach sitting on my desk in the garage for the last few days as mine was pegging as soon as you...

Re: Tachometer Died

Turns out I read the wrong pin for R5. I was reading both the R5 and R6 resisters in sequence, that was why it was so high. Everything looks good except for the dead circuit on R4. I will get out...

Re: 90-92 Tachometer fix....

yep that is exactly what I did. R5 is 4.3 Much better, so hopefully that resister ion R4 is all I need. Have to get out to the store to pick one up and give it a try today.

R2 = 3.85k
R3 = 1.92k
R4 = x
R5 = 7.28k
R6 = 2.94k
R4 is...

R3 = 1.92k
R4 = x
R5 = 7.28k
R6 = 2.94k

I'm assuming that the one on the right is for the tach. If so, it checks out.

Re: Tachometer Died

My tach and oil pressure are both on the same board behind the gauges so it is a little different than the ones in that other thread, but as far as I can tell, that wasn't the problem. I'm getting...

Re: Tachometer Died

Going to pull out the board tomorrow and check on that 4-10 resistor. That sounds exactly like the problem I'm having.

Tachometer Died

Not sure if something broke or just came loose, but my tach stopped working and the needle sits pegged at 7k rpm. It still moves and it drops back to 0 when the engine is off.

Come to think of...
