I motored most of the way to my new berth about a month ago. Had no problem with the alternator
or electrics. After I left the boat for a couple of weeks, I checked in with Harbourmaster, who told me my engine alarm
sounder was going off. They covered it with tape until I returned. On my return, I found the sense wire to the alternator
(in the nylon 2-wire plug) had corroded and fallen off. But the sounder and charge lamp continued until I removed the plug
. I decided to remove the alternator completely to clean things, and found the unit very hot to the touch. Seems strange since the engine
had not run in a month. Any ideas as to why the alternator was getting juice, which to me is the only reason to be hot? Also, I found a Delco 105A replacement on E-Bay. The current
engine is a Yanmar
3HM35F, with a 55A alternator. Do I need to replace the alternator, and any thoughts on the Delco?
