"If you left the batteries on for an extended period of time and they were reading 2V when you return there is a high likelihood you have trashed your batteries.
Depending on how far the boat relocation is you could get a new battery
, wire it into the starter battery
slot and disconnect the house.
It does not appear that you have an alternator
problem so I don't see the need to buy a new alternator
. You do have a regulator
problem and it could be as easy as replacing the regulator
If you are not comfortable with the system you might try finding an electrical mechanic
thanks I for replying again. I may have done damage to the starter battery that was working ok but is 3 years old.
I don't have far to move the boat, maybe 2 miles at most. So I could really just start it and run over there without a problem. I did disconnect the old house batteries so that won't drag the starter battery down.
The existing 3 wire alternator does charge, we proved it earlier. I think it may still have the internal regulator since it still has the connector where the regulator usually is. The ones with the regulator removed seem to have wires coming out of the hole and no female spade terminals built in. If I read the wiring
diagrams for the normal 3 wire Delco, I should put a wire from the right RPM
. I'll try again. I do like the one wire alternator that is so simple, just connect one wire to the battery and it charges.
I am still learning
this system and it seems that there are better regulators and battery managers available now so I will continue educating myself in how it works and what is current
technology. I may start looking at others at the club and asking some more knowledgeable than myself.
