Tris Cocks Posted June 8, 2010 Share Posted June 8, 2010 Hi the last alternator i had stopped working and on further investigation the wire from the battery had decided to weld itself to the casing of the alternator and subisquently it stopped working. I got a second hand alternator from a 300Tdi Disco with air con (120A i think) i had to change the pully over to get the belt to fit as the one on the end was bigger. The alternator was kicking out 14.3A of juice to the batteries when i tested it at home, Ideal problem solved i thought. At the next event i went to a week later the battery warning light came on and upon checking the alternator it had stopped working. Is there something in my loom thats caused it to go wrong (cant think of anything) or was i just unlucky with the one i bought? Thanks Tris Quote Link to comment Share on other sites More sharing options...
Jinx Reyneke Posted June 9, 2010 Share Posted June 9, 2010 Im keen to see what the others think. I have had a few problems myself of late. You don't mention anything about fuses going so I suppose that they are not blowing. I was advised to check the loom where it goes over the chassis at the back where it goes to the tail lights and tow elec. plug.Is the battery not perhaps shorting on the battery box cover?

gaz489 Posted June 9, 2010 Share Posted June 9, 2010 my towing electrics were shorting out on mine a while ago it was the grey plug and was sending current back to the alternator causing them to blow. i would say check towing electrics first especially if there is any slight damage to the plugs Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 9, 2010 Share Posted June 9, 2010 If the charge wire had welded itself to the body then I hope you replaced it. Also, I hope the alternator was putting out 14.3 volts not 14.3 amps. Quote Link to comment Share on other sites More sharing options...

Tris Cocks Posted June 9, 2010 Author Share Posted June 9, 2010 I replaced the charge wire as a matter of course, What wires were shorting out with the tow electrics, was it in the socket or the within the cable its self. Would this repair kit from ebay be suitable to repair the alternator? Quote Link to comment Share on other sites More sharing options...
gaz489 Posted June 9, 2010 Share Posted June 9, 2010 its the regulator that will have gone and my towing electrics were both actually there was some bare wires where the cables ran across the cross member and the socket was crushed Quote Link to comment Share on other sites More sharing options...
