Hi everyone -

Picked up my first Jeep last month and have started to do some work on it. I've been inside and out both a Samurai and Chevy K10, but this is my first Jeep.

Anyhow, my tach isn't working. Can someone give me a quick basic rundown of the wiring and ignition on a Jeep? Is the coil seperate from the distributor on a 2.5 4 banger? If so, where does the tach wire get the signal from? I'm gonna try and troubleshoot it tonight.

Thanks,

- Steve

Anyone?

What year? There were 2 different ignition systems on the YJs over the years.

Sorry about that. It's an '89.

Here are some pics of the coil.

Two things that I notice right off -

1) The middle plug looks like it's missing a wire on the top half.
2) It looks like a plug is completely missing from the top.

I don't see any loose wires or plugs, so I can only guess as to what should be in these spots. Anyone have any insight?

One more try at the top....

Welcome to the world of Heeps. This guy has done a conversion on his '87 to a CJ dash, but there is a lot of wiring talk in there. Maybe you can find a diagram in his thread:

Hope this helps! Gig 'em!
