Re: Tach, Alternator odd trouble....
Thank you MarkSF and Faster.
I've had the boat 7 years this past July. On rare occasions in the past (maybe2 or 3 times a year at most), while motoring (again the motor RPM was consistent and running smooth) the tach would jump to zero, maybe stay there for a moment or two, jump back up to a higher RPM reading or maybe a lower reading or both but would quickly go back to normal after a few moments.
Since I put in the new alternator and had my hose clamp fail, the tach has done the same thing as above, but only for much longer periods (up to an hour). And I also finally noticed that when the tach was screwey, it also wasn't charging the house or engine batteries.
Yesterday - Wednesday Aug 27th. I replaced the original ignition button and key. I put in a brand new key switch (like a car). I'm positive all wires are tight and connected. If this doesn't fix it, I'll assume the shop missed the stuck brushes.
