Hi there,
Ive had my alternator on a auto electricians test rig and it worked fine there. (this morning)
when i put it on my engine and connect it to battery it screams terribly loud when running (belt), the tighter the belt the louder is screams (seems liek there is a huuuge electrical load on the alternator) the belt starts to smoke.
when i disconnect it it goes silent and fine. and no smoke.
it charges fine and all.
the wirings pretty simple, 3 wires, one to charge light (and other side of lamp connected to +), one sense wire to battery + post , and the other big wire to the battery + post (tees into starter feed)
(i changed the waterpump and idler aswell just be be sure and atleast know that they are new)
what am i missing here?
why did it work fine on the electrians test rig???
theres no short to earth on the feed wire
i think its going to be embarassingly simple.
