Thread: Nissan Patrol not generating

My local auto Sparkie gave my alternator an overhaul after it died 4wding. Pulled apart and cleaned and checked and replaced brushes for $80 all up. Don’t need bearings or stator tho but could be worth asking the question, price might surprise you and you’ll have a good spare.

Good ol Dannevirke prices

Have to take an AES with you to restart your heart if you ask for a quote from most places in Taupo.

Send it up to me Simon. Ive got a fantastic auto sparky girl up here who seems to be able to fix anything for a good price.

Gives free advice too. bloody great, I dont go anywhere else.

Old fashioned service is still king.

@tac a1, Cheers, that would be great. Always good to have a spare, running two GU's now

Update: The supposed brand new 110amp 12 volt alternator supplied for my Patrol by the Nelson bays based TradeMe shop has just died. 3 months work and its dead. Pumps out 25 odd amps at high idle but only at 11.7 volts

For the electrical geniuses out there, could there be something electrically wrong with the Patrol that's chewing up alternators???? Its a bog standard truck. No mods.

Of course the other Patrol with 535,000km on it hasn't put a foot wrong in 8 years

Tried a different/new battery? Assuming that it won't be that - but worth an ask...

If it isn't the battery, then a possibility that a connection somewhere is rather crusty and not doing what it should - but if the thing was working as it said on the label when it was installed then the most likely situation is the voltage regulator in the alternator is not doing the job anymore. Should be around 13.8-14.2v at charge, 25A seems about within the ballpark assuming your high idle is around 1050-1100rpm?

I don't know what type of alt you got fitted, a voltage regulator should be good for longer than a few months but I guess they do die for time to time.

Can you check what voltage the unit is supplying at high RPM? Any possibility of belt slip or something odd like that, again that for me is an unlikely cause but it would pay to eliminate the mechanical faults before blaming the alt...

My new alternator was put in 2016.Done about 130000ks.Hasnit missed a volt.Tdi4.2.=603000ks.Hmm something a miss in yr wiring,regulators,fuses,some gezmo.Hope you get it sorted XR500.Mine start charging at about 750 rpm.
Alternator brand Mitsubishi,but it works.
