Alternator cooked?

[dpetersen]

Gday fellas!
So I’m 90% sure my alternator is cooked, just want a bit of advice/info
It’s a 2006 4.2tdi wagon with the original hitachi alternator and just clicked over 300000ks the other day.

Crank battery is only a few months old and had it load tested. Still putting out 750cca.
I’m just running the basic red arc dual battery isolator.
The last couple of weeks I have been getting a flat crank battery.
Iv checked the output at the alternator, at idle it’s 11.8 volts, wind it up to 1800rpm and it’s 12.8 volts.
While driving, if I get up to roughly 2500rpm the battery voltage does increase to around 13volts (via ecu talk).
I have checked all the connections, cleaned the earth points and tightened the belt.
So I’m assuming the alternator is cooked.
Any opinions on replacements? Nissan want $2300 for genuine so that’s out. Patrolapart are selling Jaclec 100amp for $350 or a 125amp for $400. At this point I am leaning towards the 125 amp from them unless you guys have a better option?
Question, can I charge my crank battery while everything is still connected? It’s a century 6amp 9 stage charger.
Cheers guys, Daniel

Our older 2001 TD42T one also died at approximately 350,000km too mate, replaced it with an OEM for around $500ish I thought? Are the 2006 TD42Ti really $2,300, I thought they’d be the same alternator?

Yeah that’s what the bloke at Nissan in Bundoora quoted me over the phone. I nearly fell over when he said the price. I might try a different dealer and see what price they come up with. If it’s only $500 odd for the genuine il stick with that

It may have been circa $550 but almost positive it was under $600 for the Hitachi OEM 80amp-ish which still more than suits our tourers old 80L Waeco & 26L Engel freezer so far. If we can get another 350,000km out of it I’ll be impressed and OEM rave on again if I’m still alive [emoji23]
FWIW: Some reputable mechanical shop resellers of higher amperage aftermarket alternators took them out of their offerings some time ago known. Personally bought an Ebay GQ 180amp pimped up alternator to assist gnarlier winching and not convinced it aint going to cook itself again heat wise atop of the 6.5 Chev....(very similar to TD42 operating temps)
PeeBee Mate has kindly put me onto an external rectifier pack to relieve the poor old pimped up internal diodes [emoji106][emoji106]

Even at $600 that’s not too bad for a unit that personally has done 300000ks and is 15 years and basically requires bugger all maintenance. I’d be pretty stoked too if the new one lasts that long! I’d do a bit more research tonight/tomorrow.
My set up is pretty similar to yours I’d say, not too much running off it.
I was going to look into getting new brushes put into it but I might just bite the bullet and get a new one.

Maybe take the alternator to an old fashioned auto sparky. It may not need much to sort it for another 300K.

My only honest concern these days Cuppa Mate is trying to find a decent “Old School” repairer armature sparky, almost non existent now?
Bearings are a concern too for a further 300,000km, not sure if they’d handle it but maybe Hopefully Brother? [emoji1696][emoji120]

dpetersen Could try calling this mob in Alice to see what they say? https://kcautoelectrics.com.au/services There are several other Auto Sparkies in town too, but if you are still out at Wartarrka I guess a changeover may be easier.

Charging your battery with 'everything' connected should be ok.

Thanks Cuppa, forgot to update my profile, I’m unfortunately back in Melbourne now for the time being.
I was struggling to find a genuine Nissan one and being my daily iv settled on this one for now.

I was hoping for the 80amp job but they had none in stock. Fitted it today and all is well again.
Il see if I can find someone in melb to rebuild the old one so iv got a spare.
Cheers for the help fellas

Used to be a tiny place just off Elizabeth St, Mebourne which re-wound alternators - no idea if they are still there.

Have seen a place in Ballarat which I think does similar.

Rowan Bebbington in Chiltern Vic is a winding genius. This guy saved my arse for free one Sunday a few years ago when my roadbike blew a regulator/rectifier 350km from home. Sheer luck that our paths crossed that day but he went out of his way to patch me up to get me home. Wouldn't take money, on a Sunday, because he's a champion bloke. www.codrewinds.com.au

Small coil rewinds in north geelong could probably help too. Think he's pretty good but customer service lacked when I needed him quite a while ago. Trades on his skill I think.

Awesome find DPT Mate!
Completely nuffy forgot about ‘Baxters’ [emoji106][emoji106]
They are our yard mechanics go to for truck alternators, honestly never knew they also stocked our smaller needed sizes [emoji3060]
A 130amp Hitachi “type” will surely suffice, price paid (13/01/2021) pretty please Mate [emoji120]

So it was about $490 with a three year warranty, which I thought was a pretty reasonable price! The smaller 100amp are about $400odd.
The reviews I’d read where pretty good so kinda worked out well! The fellas in there were pretty helpful and friendly too.
