hey paople i need to rebuild my 12h_t alternator any info would be helpful

if you already have it out, you can ring an auto elec and see if they can do it, or buy a new one from a shop, thy arent that dear, plus you can get a bigger one too, i had an 80 amp hr one on my 12ht

i got a quote 350 to rebuild or around 600 for a new one. sounds dear to me

Depends on what they are doing to it. I had a 200a alternator rewound and it cost $450 on the bench.

If you shop around you can get it cheaper than the prices you have shown.

What is actually wrong with it that needs t be rebuilt? bearings gone? It may just need new brushes which is a reasonably easy job, and cheaper too......

that said I would get the bearings done when the brushes are replaced, easier to do it once, rather than pull it apart twice.

P.S.

I bought a new 80A alternator (internal regulator) for $250.00 Was mates rates though, via ashdown ingrams two years ago.

yeah thanks for that im going to look around its just no charging ill have a look at getting some bushes

best to get it bench tested, if its a denso it wont be cheap, but its worth its weight in gold.

What is it exactly doing, or not doing. I.E. not charging at all or a non regulated charge, you will have to put a voltmeter across the battery posts while it running and gently raise and lower the revs whilst reading the volts to get a better diagnosis.

Might not be bushes but the manual will tell you the minimum lengths for the carbon, could also be volt regulator, some are internal some exo depending on the alternator itself. I think you can tell by the wiring on the alternator itself by memory but not 100% sure how.

its not charging i pull a volt meter on it and it sits on 12.59 wont go higher then that.so i was thinking bushes

thats fuggin amazing we just bought a 60 series with a 12ht in it and a stuffed altenator i bought a brand new 80 amp alternator for me 3f petrol troopy 450 bux but it might b dearer on a diesal get a buying a new ones most of the time can b cheaper then fixing a stuffed one

The diodes often give up in these alternators but check the brushes.
I bought 13/1/10 a new alternator including vacuum pump from A.E.D for $350.00, 12v, 80amp, int reg 2H/12HT part no 098-13-840. Regards.

the 80 amp alt i bought was under 400, if i rember right, trouble is where i got it has since closed down(maybe cause they were undercharging)

Haha.. I get it. Undercharging alternators...



Just had the exact same problems. Replaced voltage regulator and one faulty diode. Also replaced brushes but they weren't required.

Cheers Mate, I bought mine here in Townsville but the alternator was sent up from Melbourne as they did not have one in stock, usually they carry one.
Check yellow pages your area as on my receipt it says they have branches in Clontarf, Archerfield, Townsville, Mackay, Rockhampton, Sydney, Newcastle, Launceston, Melbourne,Adelaide, Perth and Darwin, but does not show phone numbers for these.
Australian Electricial Distributors Townsville is [07]47550050
Best regards,

im going to call A.E.D see what there got. not sure about putting sumthing that nice on my car lol
