One gauge light not working

[Jack Schneider]

The bulb behind the oil pressure gauge doesn’t seem to work... I’ve replaced the bulb twice and the second time it did light up but a few minutes later stopped working. All the other lights are fine. Any ideas?

 

[Jack Schneider]

So the bulb works until it snaps into place on the back I found out ... not sure if this can even be fixed

I got some leds that i could turn to far when twisting them in. Once that far they were off the circuit and hence wouldnt work.

 

[Jack Schneider]

I have no idea what I did but it’s fixed for now... [knocks on wood]

Damn

OH! That sucks canal water!

 

[Jack Schneider]

So I replaced the back board with one from a low mileage junker and the coolant gauge works now but still not the odometer and speedometer... any ideas? is there a fuse for the speedometer?

If I got a cluster with a tach, would it work??

 

[DerekTheGreat]

Yes, it would work. Well, I believe it would. I believe the 91-94 trucks are wired for either cluster. I've never owned one but am familiar with the '88-'90.5 slice 'o' pie goodness and the associated conversion.

If your truck is a V6, pull a tach cluster from a V6 and if it's an 8, make sure to pull the cluster from a V8. Otherwise, the tach will be off. I'm not too sure about that though but it's what I do to be safe.
