Anybody have one? I'm trying to find out if I can attach the hot lead from my mazda directly to the VW alt. A buddy said I should find the schematic first
Also trying to get an answer for the 2 small wires that come off the altenator next to the charge wire
thanks
BTW, searched without success
94 AAZ motor. jetta from canada
hope you can help

how many wires does your mazda have for the alt? according to my wiring diagram. its not specific wether or not its canadian or usa production. doubt it makes a differencr though. theres only 2 wires to the alt. a big red wire that goes from the B+ alt terminal, and a blue wire that goes to D+. no your mazda probably has 2 wires aswell. the big red one or the one that goes to ther battery terminal goes to B+ and the other would go to D+.
There is a smaller red/black (I think) wire connected to the W terminal. It is the signal for the tach.
you might be correct. but his mazda wouldnt have that wire
the w terminal, im sure has a different wave form, than the ignition coil so his stock mazda tach probably wouldnt work with the alt. so adding the wire is pointless. so either it works or he fries the wire and maybe his cluster.

all modern car alternators are three phase. so you can definitely add the W terminal to any one of the three phases. the alternator might need to be opened though, but that isn't a big issue.
your correct. but my point is the mazda tach wont read the w terminal... so why add the wire or terminal

ok so to get this right, you have a VW alternator in your Mazda. i'm assuming that you swapped a vw diesel into the Mazda?
alternators are generally the same and if your goal is to get the alternator just to charge, then that isn't too difficult. you just need the hot lead connected, and the 12v exciter wire to energize the rotor for charging. if you really want your tach to work, look for a dakota digital converter. it converts the W terminal signal to the same signal as a spark plug.
on this topic, i've been very interested in learning more about 3 phase power. certain accessories could most certainly benefit from this power source, such as any motor inside the car whether it be blower motor or window regulator motor. since the power drop is virtually nil over the course of 100 feet, it would be most efficient, and diodes/rectifiers could be used wherever DC is necessary (radio, lights etc) but i won't get any deeper into it
