RPM gauge volvo 240

There are 3 electrical connections on the back of the tach. The blue/red wire goes to the #13 8 amp fuse, the center wire goes to the black wire that comes off the distributor, the third wire is ground.

The sender is the pulse at the black wire on the distributor. It's an electronic tach.

If you just replace your clock with the tach it will draw power from the pins on the cluster and there is a red/white wire in back of the cluster to attach to the #1 termnal on the back of the tach. If the small clock is there grab it and the harness which will plug onto the 3 terminals at the top of the tach. These small clocks have an illness in some (most?) of them caused by bad capacitors, finding a good one is about a 50/50 deal, if the yard offers a guarantee for an extra buck or two it may not be a bad idea to get it on the clock, I've never seen a bad large tach.

Yea i saw that wire and was wondering about that. And i already looked for those smaller dash pods that are to the right, and they were all riped out. Whoever went in there to get parts must have used a crow bar. The entire dash was ripped apart. In fact there were 2 gauge clusters in the car but one was from a 82 242 next to it.

Thanks again.

Sorry, I forgot to mention Volvo changed the face colors of the gauges, there will be a small difference between a mid '80s tach and the rest of the gauges on your '91. Dave Shannon snipped-for-privacy@cox.net (Spring Valley CA)

Wont be a prob if i get those white faces. :)

If you have a bad small clock I can fix it, it's not hard at all, I'd install brand new capacitors in one for probably $20.
