beltandbraces Posted June 6, 2009 Share Posted June 6, 2009 Hi there, I need some help, as a newish Land rover owner, I am coming to terms with all the things that will keep me out of the house and under the bonnet. I think I need to replace the alternator on my 2.5td 110 county as the output drops as soon as I put main beam on and I get the glow plug light glowing gently which I guess is telling me I am drawing from the battery and not from the alternator. I have checked the belt, it had been loose but is now correct. Also, I have noticed that if I am driving at night and the charge is in the red, my temp needle creeps up a little, into the black band beyond the white. If I stop and apply the handbrake, no foot brake and go into neutral and knock the main beams off, the charge rises and the temp needle falls. I have done this several times and it is the same each time. Is there an electrical reason why the temp guage is being affected ( I don't think it is the water pump since the belts are working at the right tension)? It is a non a/c but I want to unprate the output from the normal 45 amp to 85 or 90. Can anyone assist in advising which alternator I need to buy. I have had a look at the wiring and on the factory fitted unit, it is a multi plug in to the alternator...not posts and blades. Any help to get the right unit is most welcome.

western Posted June 6, 2009 Share Posted June 6, 2009 you can either have the existing alternator reconditioned & tested or replace with a 65amp variant but you will need tp upgrade the wiring from alternator to the battery & stater [the brown thick wires] for a 65amp alternator you need a Lucas 24220 A127-65/lLR part RTC5680 unit the existing pulley & belt is common to both 45 & 65 amp alternators. craddocks/paddocks/brookwells & other LR independents should be able to source & supply.

Retroanaconda Posted June 7, 2009 Share Posted June 7, 2009 I got a metro alternator from the scrapyard that had the same fitment, gives me 70 amps Take your old one to your local scrappy and see if they can match it up to anything. Should be able to save yourself some money over a new/recon unit if you want to, mine was £23.50 and came with a 12 week warranty too.

Thanks, I am thinking that if the alternator is under performing through age, I might as well replace with a 45 amp as I am not fitting anything else to draw power. i have a line on a replacement part and may be able to have it fitted...
