I got around to removing the alternator on the weekend & the auto electrcian declared it dead with multiple problems. He did say that it wasn't leaking but it also wasn't charging
at all. I was there when he tested it on his test bench.
After pulling it down he said it wasn't worth repairing as it had already been done before & there were multiple problems & it appeared to have had a hard life. Not surprising since ours is an ex-charter Lagoon 380
with nearly 7,500 hours on the motors.
Anyway he has tracked down a 110amp alternator (to suit a Nissan
4WD) with the same mounting configurations & said that it will do fine.
The problem is I know the main Bat terminal is for the positive leads, & the Tee shaped plug
is there also, but the lower terminal with 2 wires from the wiring
harness on the old Hitachi is a mystery to me & doesn't exist on the new replacement. The auto electrician said that it was a 7 volt neutral for the Tacho etc & he wired a lead into the new alternator to provide this.
I do trust the electrician as he is very experienced, but can anyone confirm this before I hook it all up? I would hate to blow a brand new alternator or anything else.
