So we warm up the boat, pull away and about 10 minutes later we get a low voltage alarm on the engine instrument panel. Voltage meter showed <10v.
We are at low RPM so I increase speed and the alarm goes away and the voltage comes up.
About 30 seconds later voltage drops, alarm sounds, engine sputters and dies. Dropped anchor and called Tow Boat US and they are estimating a 5 hour response time. So, I might as well be useful and try to trouble shoot the problem.
We still have DC to the instruments, meters show 12.9 volts. Measured voltage at starter and it is 12.98. Installed a new fuse recently in the house bank but it is still good.
There is a fuse in a small red wire off the alternator positive post and it is good. But there does not seem to be continuity between alternator positive and negative posts should there be?
When we turn the engine key on there is nothing.
Suggestions?
Thanks,
Gene
