My Volvo lump has a vacant fitting and wiring on the port side for the standard Alternator.
On the Starboard side I have a Prestolite Alternator rated at 90 amps working perfectly to two battery banks.
Both sets of wiring go to two sterling alternator controllers.
Currently the Prestolite alternator (a new one last year, I smoked to old one) is not wired through to the controller, just working as nature intended. I couldn’t face taking the covers off and soldering a wire onto the lump that cost a b;**dy fortune. Add to that the man in the shop said that sterling controllers cook alternators with small pulleys at low revs.
The wiring is in place for the second of the dual alternator setup and it should be a simple matter of mechanicals (ha) to bolt in the new port one.
Both sets of output wiring seems to be connected to a “1 Both 2” switch, I’ll check that though!!
The added advantage of a second alternator will be the second belt driving the water pump and separate charging for domestic and engine battery banks.
My question is will it pop both alternators if they are inadvertently connected together?
It would be good if one alternator carried on if the other one failed etc…
