Tachometer Problem..

[Rost]

I glanced down at my tach tonight while cruising along. It was right at 5000 and all of a sudden it just dropped down to nothing. Like I turned the switch off. Any idea why this would happen?....Marine man..are you out there??

Correct me if I'm wrong Valv... but wouldn't a incorrect pole setting on the tach result in false (too high, too low) RPM readings, and not erratic, or no readings at all?

Well guys, the drama is over. The dealer called and informed me that it was simply a bad tach!!!!! Wow, what a relief! I do appreciate all of the help everyone has offered! Thanks again..

You are correct Marine_man but since it was an erratic function I thought maybe it was making bad contact.

I'm glad it was just a tach... in my opinion that really underscores the whole reason for conducting the proper tests, etc on a motor before just replacing parts... in this case you probably saved yourself about $300 by not just replacing parts and actually finding the root cause before replacing parts. We can all make educated guesses as to what the problem might be, but until one really gets into it they're all just suggestions of what to look for...

Ehm...if you start with tachometer and you buy it from KV Enterprises (me) it's only $ 12.50.....

That's a cheap way to troubleshoot.....right Rost ????

I will call you either tomorrow or monday to order one.

Thanks Valv!

True Valv.. as long as you're a good guesser!
