Wiring Alt With Internal Regulator


Go to solution Solved by GreenSwede,

Recommended Posts

Found this, so the wiring at the alt is clear. But the old regulator and wiring? Just let sit? Through out regulator and let wiring sit?

 

"The 320i alternator is internally regulated, so 2 wires only need to be hooked up. The wiring is very easy. The thick red wire goes back on the 320i alternator, on the "B+" post - this wire does the charging. Cut the BLUE wire off the stock 3 prong harness and connect it to the "D+" terminal on the alternator."

When I did this mod some years ago with a 1985 318i 85 amp alt, instead of cutting the blue wire from the three prong plug, I took a length of blue wire crimped a male spade connector on one end and plugged it into the corresponding blue slot on the three prong plug.  Then wrapped the plug with electrical tape and tucked ot out of the way.  This way if there is a desire to reverse the mod simply remove the blue wire from the plug and re-install the original bits.

All good, but we´re still talking about the 3-pole plug at the alternator, right? I´m thinking about the regulator and the 3-pole plug there?
