Massey 398 isn't charging
Back of the alternator has a 3 prong connector, looking around on the web, looks like (1)
D+ and (2) B+ terminals
Want to troubleshoot before I buy an alternator
Assuming (we all know where that gets you) the D+ should have 12V+ on it to excite the
alternator...and the 2 B+ are the output to the batteries...sound right?
So if I've got the 12v, it should charge?
And the replacement alternators have that 3 terminal connector, but also have a large B+ stud...would I just cover that up and ignore it?
Thanks
