Alternator Q

72 350 - battery died, got it jumped to start - on the way home turn signals, light all out or dim...I'm guessing it's my alternator...couple of Qs:

1) The back say Delco Remy (made in America) - This looks to have the voltage regulator as part of it as I see no external one...am I right here (see photo).

2) I only have one red wire coming off the back - assuming this has an internal voltage regulator - is this set up still correct? (ie. should there be other grounds or such?)

I ask cause, Autozone has two alternators - one with external VR and one internal.

Thanks, TT

Re: Alternator Q

The green wire is for the coolant temp sender that is mounted in the cylinder head. That looks to be a one wire alternator and looks to be wired correct and yes it has a internal regulator.

Re: Alternator Q

somewhere on the alternator is a two prong connector. if there is nothing plugged into it, you have a "one wire" alternator. you need to make sure the replacement is also a one-wire.
a picture of the back of the alternator would give more info
