When I replaced the 90A alternator with the 110A alternator, I really noticed a difference in the speed of the wipers and fans when commuting in the dark and the rain. Instead of slowing down like they used to, the wipers and fans now stay at the same speed when I'm at a stoplight. I didn't notice any difference in the speed of the starter.

Well worth the small effort to replace it.

Hi, I have the 94 2.2. If I get a later model alternator from the ones you described, how bout the wiring harness at the alt. Do they have to be from the same year or do multiple years fit?

My local piknpul only has vehicles up to 2002 and not many at that.

I got mine on ebay for $30 shipped and no tax.

Missed that post on page 2 about the harness. All good here. Thanks for the info and input

Another improvement I now do on these alternator upgrades is to purchase a 4 gauge marine grade tinned wire and run it directly from the charge stud on the alternator to the starter stud on the van. You can buy these pre made and crimped on Ebay by length cheaply. You then remove all the original patched together charge wires, which are usually larger gauge white on the Subaru end and red on the Vanagon end.

This upgrade requires the 5/16 diameter ring terminal on both ends.

I'm just wrapping up the rebuild on a 2003 EJ25. I want to upgrade the alternator while I'm at it. The original alternator fits well on the pivot bracket. The new 110A one has a lot of slop front to back. Do I need to find a mount from a newer engine? Maybe use a washer as a shim? I'm concerned about belt alignment.

I've tried battery + 12v to every wire.
Only the black/yellow has any effect. I get 15.3v at the battery+ terminal, and 6.3 volts out of the black/red....not enough to turn out the idiot light.

If I apply 12v to the black/red, I get 1.3volts at the black/yellow, but not any charge voltage.

Must have a bad alternator? Or is it computer controled?


If it matters I am not testing with the idiot light circuit attached to the alternator. I fear that the fridge relay and aux. battery relay may cause issues with the light not going out as well. I should be able to read 12volts at the wire that will go to the idiot light without it being connected?

Maybe start a new thread? Specify you have question for ee20 diesel. Greg should know.

[Franz]

Maybe a moderator could split my ee20 stuff from this thread?

I've been talking with boxeer.com Greg. He didn't know. This is one of his euro 6 engines that he was selling a year and a half ago.

He had one of his other customers contact me to tell me how to attach the wires.

I think his customer may have the euro 5 engine because the plug at the alternator looked different, and his wiring did not work for me.

Or I have a bad alternator. Which would be Greg's issue again.

[Franz]

I just pulled the alternator off.

It has a one way clutch on the pulley. I can spin the pulley and armature independently. See the bearing on the end of the pulley? Has anybody seen this?

[baltik]

Ok, clearly I'm an idiot - i want to upgrade my alternator with a rebuilt unit I got from Rob

I have the old style 2 wire connector

I bought the new style 3 wire alternator harness

what do I hookup where?

[termuehlen]

For the 23700-AA370 alternator, the pin closest to the 12V+ Post is connected to the alternator light in the instrument cluster, the middle pin is connected to 12V+ field wiring to "sense" the voltage, and the last pin is unused (farthest away from 12V+ Post). If you do a search here you will find numerous posts with more information.
