I own a small marine diesel
(bukh dv8) and have recently been having alternator charging
problems (12.6-13v only). This has come on rather suddenly... Before hand I was getting a solid 13.4v.
I recently had a problem with the engine
key switch, it physically jammed . To get the engine
going I though I was macgyver and hot wired the starter wire to positive and got it started no problems.
It then occurred to me that the alternator
was running without the "accessories" on, as the key switch remained in the off position.
Could this have damaged my alternator/diodes?
