Mk6 2.4tdi not charging?

[JRHartley]

Ive put a early one wire fuel pump on this 2.4tdi, I purchased this van with a pump fault & Im not sure if the charging system was working before I changed the pump.
I know of some one doing the same pump swop & found the charge light now stays on, but he's getting a charge from the alt'.

Is there some thing Ive disturbed on the right side of the engine bay, solenoid? wiring socket etc? or is the alternator done. Is there a more basic alternator that will bolt straight on? any one have a schematics of the charging system? Thanks for any help!

What voltage are you getting engine running across battery.. ?

[JRHartley]

12.4v at all rpm, I read its a smart alt? I wonder if I could strip it down & use regular diode pack & regulator?

Mk6 doesn't have a "smart alternator"...if engine is running, you should have ~14.4v across the battery. Is the battery itself ok..?? Have you had it properly load tested..?? Not just a voltage check.

Ive not had it load tested, would connecting a another battery via jump leads do for the test? thank you

If memories serve me correctly, on a smart charge alternator the voltage goes down under load .. i think.. perhaps opposite. Silly idea!
Dk if yours has that or not.. how many connections on the multi plug on the alternator?

Either way, if voltage aint changing atall. It dont sound happy.

On smart alternators pulling the multi plug off effectively makes them a normal type.

Check directly at alternator end on the big red cable and to ground on alternator casing.

It has one socket with two thin wires & one thick feed wire. I think Knobby is correct on this being Non smart?

No...the battery has to be "loaded" using a proper battery tester.....sometimes they can show good voltage but fail miserably when loaded.
