[Vwdiesel] Vw alt wired into JD, directional rotation

travis, yes, i had two seperate occasions where the alt charged only in one direction (in the on bench tester) and not the correct one so it created a confounding situation when i put the alt in the car.
as far as a replacement, i thought i should purchase one from a nation wide resaler as i will at times be on the road traveling with this passat wagon and then could replace the alt when and where it goes bad.

So you say it won't produce a charge in the oposite direction? I just want to clarify that. And if you are asking who does a good alt-a rebuilder-not an exchange.

this discussion is timely as mine had just gone out

having several alts in my inventory, i made a testing rig to see which ones where still good, using an electric motor to spin it and a battery to load the output.
i found that an alt could function in one direction but not the correct direction, also, it needs a battery to receive the charge to accurately function. quite handy for these old cars


question: has anyone found a brand, sold by a major vendor like autozone, that holds up well. mine is working for now though i thought i might buy the duralast version from autozone and quit fussing with my diminishing parts bin. 


also, with all the talk of the idiot light placement in circuit,  i am confused as to where i might wire in a volt gauge.
