Renault master 2500 diesel van Alternator

[camerart]

Hi,
I have a Renault master MM33 DCi MWB 2500cc Diesl van 2004
The batteryand STOP light have come on, so I assume the Alternator has gone. Is there a way to test it to make sure, please?
At the Battery there is no difference to the voltage when the engine is running or not.

That's a pretty good test you've done and I guess the alternator has called it a day. Waggle the connection at the back though, keeping an eye on the meter. I assume the drive belt is still there!

I would concur with John. Voltage should be about 14.4 volts if the alternator is charging. On some alternators you can just change the regulator assembly which is a lot cheaper. Find your alternator identification and look on ebay.

Hi, Yes, the belt is still there
The Alternator is warm when running, which made me wonder if it is working, but not delivering.
Ho do I find the Alternator identification?

Usually there's a sticker on the back but you may have to drop the thing to see it
An exchange unit from a motor factors may be the way to go.

I just had a look, and the sticker can't be seen.

MOT on Tuesday, so I checked everything, and a headlight bulb has gone. It took me 1/2 hour to unclip the bulb, which indicates to me that my time of changing Alternators has passed.

So far a quote for the Alternator, belt and Tensioner is £550, and probably plus VAT. What happened to cheap vehicle repairs?

I had a car that wasn't charging and it turned out to be a wire damaged internally. I seem to remember it being called an Xciter or something?

 

[Burnerman]

Yep, to get current out you have to have current going in....the exciter current.

Hi,
Just got back from the garage.
Exchange Bosch alternator, tensioner and belt.
Oil flush, new oil, filter.
Total, £580.

It's a lot of money, but it's done now, with a guarantee, so that's life.
Cheers, C.
