Have a 4.2 diesel, and during the long weekend in Toolangi, my alternator has died. I assume that I've filled it up with mud or water. Is there an easy fix or is it back to the auto elec, as it has had new bushes and bearing replaced after the Easter trip.
This leading to the 2nd question. When alternator dies, batteries both flattened, should this lead to engine stalling. Is the fuel pump on these models electric or have i other problems.

yup.. happened to mine on way back from Border Track... car rolled to a stop, both batteries drained.
Just about all small deisels have a vacuum pump fitted to the alternator depending on the type of brakes the vehicle runs. When mine went the shaft was worn where the vacuum pump seal runs. The only way to fix this is to get the shaft repaired otherwise the pump will leak after a while.
I just fitted a new unit which cost me $550 & comes with 2 years warranty. Hopefully it will do another 340,000 kilometers.

You shouldnt do that as the alternator will spike & blow up the regulator & anything thats electronic & sesitive.

I have just been through the trauma of a buggered GQ alternator. According to my Auto electrician "mate" the unit that was on there was a grey import for which no parts were available. He ordered one up from brisvegas for me (85A) bolted it straight up and then sent me the bill...
$730 big ones
I am now waitng for the thing to offer a blow job when I lift the bonnet. Hasnt happened yet but by god it had better !

The standard td42 alternator does not like playing in the mud.
After a days play, on the trip home when the mud bakes dry inside the alternator, and its now dark and alternator required for lights, the brushes stick in the brusholders.
A good hoseout with the garden hose (not the waterblaster) could save you a trip to the auto elec for a stripdown and clean.................You have already drowned it it mud, so a wash in clean water is not going to do more harm.
The bearings should be sealed. If they are not, theyre full of mud anyway!
Also, when the charge light first starts to come on, give the back of the alternator where the brushes live, a sharp tap. This can often free the brushes and get you home.
The TD42 engine uses a 12 Volt solenoid on the fuel pump to open the fuel supply to the pump..........No electrics.......No fuel.

thanks quys, shall give the above a try, then maybe off to the auto elec. Is there anyway of 'waterproofing' or 'mudproofing' the alternator so this does not reoccur

I thought my recent alternator probelm was terminal and purchased an aftermarket 70A job for $450. (No choice was stuck) when I got home pulled the old one apart and it turned out to be two dollar rubber seal
between the vacuum pump and the alternator. Oil had gummed up the commutator rings. Cleaned it up tried it again and I now have a spare.
Dead easy to pull apart to service/fix.
I just ordered a 12v 130a alt with vac pump from the local truck mob. Will cost 550 fitted 
Will beat the shit out of my 40a one.

IF you guys need an Alternator , i used one of a nissan serena van they are turbo diesel and they basicly bolt straight on 110 amp standard and all wiring is the same, i wreck imports at work and when we have they they are only worth like $95- $120 so keep in mind if you need an alternator Import Nissan Serena, i have one on my truck works mint..

Alternators. I hate them. I just had to replace mine on my 24V Safari.
Bare with me while i explain an idea i have been playing for a while:
I had an Ex Possum Bourn Subaru RX Leone, ex works WRC, ex Yuha Kankonen (sp?)
Any how, it had all the good shiat as you would expect, did i metion i bought it after it had been rolled??
Well, on removing the engine, i noticed the alternator.
Infront of the fan on the front of the alt, between that and the pully was sandwiched a 3mm plate, the same diameter as the alt fan. The idea i guess, to deflect dust and water, and prevent them from entering through the font of the alt, whilst still leaving the blades of the fan exposed to provide cooling.
I rekon this would also work to an extent on a 4x4 in an off road situation, but am worried about overheating the alt, as rally cars travel at speed with plenty of airflow, not crawling along in Low 1st.
I may give it a go soon, as i do alot of river driving and the brushes love fusing!!!!

What about bits to rebuild them if they shit brushes (are they all the same on all cars? etc? any ideas?
Also do they have Vaccum pump on em?
Sounds like a great tip to know!
