intermittent tachometer

[sunbird]

I have noticed that sometimes while running, the tachomoter starts bouncing, then dies, then works fine again. From other posts I thought it was the regulator/rectifier but when it dies the volts stay the same. I asked a mechanic and he said it could still be the regulator/rectifier or maybe the powerpack. Any ideas before I make my mechanic a rich man? Is it hard to replace either of these parts? I am thinking about trying it myself. I have a 1990 120 Johnson VRO.<br /><br />thanks

Have you checked your wiring for a loose connection anywhere ? Check for continuity and then wiggle the heck out of the wiring with the probes on and check again, could be that simple, then again maybe not.

thanks, I'll check the wiring. Hopefully I will get lucky.
