What you are looking at

No photograph available

We do not hold a verified photograph of the Alternator yet. We would rather show none than show a picture of a different part.

What goes wrong

On the VDJ200 the alternator sits low at the front of the V8, directly in the firing line for water, mud and sand thrown up during river crossings and beach work. Alternators on off-road-used trucks commonly fail early or die outright after a deep crossing, leaving you stranded with a flat battery. It is one of the best-known 200-series ownership gotchas in NZ/AU four-wheel-drive circles, and many owners fit relocation kits or aftermarket sealed units.

What you would notice

Battery/charge warning light after driving through water
Whining or grinding bearing noise from the front of the engine
Dim lights and slow cranking
Voltage gauge reading low

How to check it

Where to look. Low on the front of the engine, behind the radiator — visible from underneath

Look low at the front of the engine for mud staining and corrosion around the alternator.
Check for dried mud lines on the chassis showing how deep it has been.
With the engine running, put a multimeter (or the dash voltmeter) on it — expect 13.8-14.4V.
Ask whether the alternator has already been replaced.

Parts involved: Alternator.

What it costs to put right

$800 to $1,800 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has it done river crossings or beach driving?”
“Has the alternator ever been replaced, and with what?”
“Is a snorkel fitted, and was it used in deep water?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.
