More complicated gremlins

[bobk]

Well darn, now we have another identified gremlin and it seems related to the battery voltage. The synchronizer has been acting up and the slave engine throttle doesn't always disengage when the syncronizer is turned on. Today, I noticed the slave engine (stb) is showing 10-11 volts when the Glendinning is on, and normal 14 volts when it is off. It is a consistant thing now. The Glendining is now completely dead and will go back for a rebuild. So it looks like the charging system is OK, but how can the Glendining cause the voltage meter to show low voltage. The battery bank seems OK reading 13.5-14 volts with hand held volt meter even when the ships instruments show less.

you got a bad wire/connection causing a voltage drop. It's before the load. Check all your wires.

You can take a volt meter and put a load on the circuit and then measure the voltage starting at the load and making your way back toward the battery. As you make your way back you will eventually reach full 12 volts.

Could it be that the solenoid in the Glendinning has gone bad and/or is shorted out causing a very high load and the commensurate voltage drop?

Glendinning also suspects a bad solenoid could be the cause. The unit needs a clutch rebuild too, so as soon as we get back to the Yacht Club, it will go back and we'll see if that corrects the problem. If not, I need to get into tracing electrical issues.
