alternator repairs.

[gtodave]

the alternator on the legnum that i bought was dead so read the how to remove thread,removed it after a bit of a fight as the bolts were very tight and the car was not at my place so tools were a bit scarce.
got it out took it home to the work bench pulled it apart hoping to find short brushes,no such luch,tested the rotor and fields both appeared ok.
it had to be the regulator/brush holder/diode bank.
rang a friend who wrecks mitsubishi cars to find out if a v6 magna was the same,discribed the alternator and 4 pin plug to him,he said the lancers have the same plug on the regulator.
went for a drive as he lives 40 min away,checked out the lancer alternators to see if they could be bolted in,unfortunately not easily,1 of the alternators looked to have the same reg/diode bank so i bought that from him for $35.
got it home stripped it down the regulator was the same but the diode bank was slightly smaller,the 2 parts are soldered together by 2 flat plates,
unsoldered both regulators ,soldered the langer reg to the legum diode
bank,assembled.
decided to get auto elect i know to test on bench as i did not want to bolt it back in if it did not work,told him what i did and he agreed that it should work which it did on the bench.
bolted it back in to legnum ,much easier to bolt back in as i had correct tools , started the car and check light out,voltmeter confirmed 14.3v
great.
CE lancer regulator will work in out cars,cost $35 and a few hours.
i should have asked the auto elect the cost of a new regulator,next time i see him i will because it may be cheacer to buy new reg than complete alternator from wreckers.most failures will be the regulators

Good to know, top work!

Yeah good stuff but wouldn't a new regulator pretty much cost the same if you bought it from a supplier like ASHDOWN INGRAM?

Thanks for reporting back Dave, this will definitely be helpful for us VR-4 owners
I'll let Gorgs know to peep this thread out, he's having problems with his alternator at the moment.

I'm having probs too. Is there are part number or something for the regulator? Or is it a universal part?

Also just to let you know that the 100amp alternator from a pajero I think goes straight in and apparently the 100amp units are more reliable.
I have a spare one at home if anyone needs but shipping from kyrgyzstan may be pricey??

The alternator guy here charged $9 to fix my old one so I guess that if you start to see issues with voltage you should have the alternator removed and take it in for repairs especially if you run some big amps.

sweet. i need the alternato thing. on my way to my mechanic now and see what they say.

edit: since we know it is compatible with pajero, my mechanic is trying to source one for me at the moment.. will give you updates soon

Thought these pictures from ASA might help shed some light on the subject

First is Diagram of Alternator assembly

Second is a complete list of all consumable part #'s for the Alternator.

I have checked these Part #'s are the same for 1996-2002 Series1&2 Type "S"&"V" ie all VR4's.

Your second picture is missing the first 7 rows.

Yea I realised as soon as I put it up, so I cut it back to just the bits that concern the discussion so it fits in the screen dump.

as long as it helps.......
