I have noticed this happens when I am cruising with the generator on, and the battery voltage gets to high. I will turn off the inverter battery charger, the voltage will drop back to a lower value and things are good to go.
We have a circa 1975 engine panel with Motorola tachs. A couple of questions since the subject is on the table:
1) All four of the tach's read slightly differently. Is there an adjustment screw somewhere?
2) The tachs do not move when the engines are started. It is necessary to rev the engines up to about 1500 rpm in neutral when the needles suddenly jump up. After that function is normal even down to minimum idle. Is the normal?

I recently re-calibrated my circa 1979 Motorola tacs. There is a small white plastic plug on the back of the tac that needs to be removed. Screw driver adjust thru the hole. I recently went to electronic readout on the MFD using Actisense. So now the Motorola tacs are more for back up but I still wanted them to be accurate.
They don't read immediately because your voltage regulator probably has a delay before it "turns on" the alternator. Mine is about a minute or two after the engine starts.We have a circa 1975 engine panel with Motorola tachs. A couple of questions since the subject is on the table:
