My tach isn't working. Is the only way to check it is with a multimeter. All my tools are at my dads house about an hour away. I just want to see if there is possibly another way, before I make the drive out there.

OK. I just tried a new cluster today, and that wasn't working for me either. So I know I am having trouble with the tach signal wire. I know which one it is. How can I check if its good.

I read to ground a test light and poke the wire and if it surges then its good. But idk. I know there is other ways to test it. I know which wire is the tach signal wire behind the cluster but where does the go, what does it connect to.

Any help is appreciated

u need a meter to test continuity of the tach signal wire from distributor to the back of the cluster should be a blue wire or visually inspect wire for damage if u dont got a meter

I checked. I am getting .015 at dizzy and it goes up when revving. I checked at cluster and was getting same but not going up when revving. Also checked blue wire with cap I'm the engine bay on driver side and I was getting .009 and it would only go up to .010 or .011 when revving

I checked AC voltage

Do you know anyone you can swap distributors with?

Nope. My next step is I have an old after market tach somewhere I'm gonna hook it up and see if it works. If it doesn't then would I have a distributor problem?

So I couldn't find the one I had. So I went and picked up a new aftermarket tach from autozone. Just tried it right now and it didn't work also. Is this an ICM problem? Because the ICM sends the signal to the cluster right?

Yes
