teaandbiscuits Posted May 18, 2010 Share Posted May 18, 2010 morning! not sure if here or the part number request place is best for this but... i need a new alternator on my 300tdi defender. there seem to be two listed, a 65amp and 100amp. are they interchangable depending on the load or do you need to use the right one. going by a few posts on here, wood auto have been recommended and they seem to work out cheapest for the 65amp one. will this one wood auto fit the bill? i think i need to replace the belt at the same time as its looking a bit worn. worth doing the tensioner at the same time? cheers!

scube Posted May 18, 2010 Share Posted May 18, 2010 65 amp will work fine.. You don’t have heated screen air con etc. Saying that if you can stretch to the 100 amp I would stick that in. Tensioner? Not unless it’s making a noise or feels wobbly Quote Link to comment Share on other sites More sharing options...
nicks90 Posted May 18, 2010 Share Posted May 18, 2010 if you upgrade your alternator i would also be very tempted to upgrade the wiring out the back of the alt as well. The wiring thats there will only be rated to 65amp, if you have a high drain moment and the new alt starts chucking out 100amp, you could potentially let the smoke out.

teaandbiscuits Posted May 18, 2010 Author Share Posted May 18, 2010 potentially let the smoke out i'd like to keep the smoke in, doing its job :-) 65amp is what i think i'll go for. no problems with wood auto? Quote Link to comment Share on other sites More sharing options...
