All a matter of perspective mate. I reckon $66 is pretty cheap. It all depends what you compare it to. From memory a TD5 alternator is near on 10 times that amount...

td5 alternators are $450.. + about $150 to fit the bugger.

charging volts should be about 14ish anything over 13 is good enough for a beater.

you can get that alternator for $50 dollars or a later model unit with an internal regulator for the same money.

looking for the diagram on the voltage regulator you have there, you should be able to replace the alternator with an internally regulated item. or If I can find the layout of that regulator you have there that one can be canabilised with a bit of soldering and some 30a relays.

if you've got a goodish set of spanners and know your way around the multimeter we can do the "over the net" strip of the alternator testing it and then set it up....


for the next step put it all back together with the cap off of the "regulator" pack and using a plastic thingy (the back of a small screwdriver works really well) manually close the contact points on the relays and see what that does for your voltages.

I cant get the wiring diagram for that component off of the net. can someone with the haynes or OEM manual post up the pics of the diagram.

and I found a couple of dozen listings on Ebay for alternators that are internally regulated that should do the job but will probabley need some minor fabricating and wiring mods to get to work.

I assume potentially sub $20 for an alternator is ok?

Thanks dave,yeah i'm looking to replace or fix but theres no hurry cause we can use the rover plus we not doing to much till the move anyway..

Hey Dave i didnt even think to look at fleebay just had a look & found one the same as ours for $50 & i sked him for a postage cost ,its from QLD cooroy i think it was..

Ok we had the alternator tested at the auto sparky's he said it seems good ..so we tested the voltage regulator going by the workshop manual all was good but one reading it had to be 11 omh we got 10....can anyone think of anything else to try we are going to put the battery out of the rover a bit later & see if that makes a differance plus i will check all the wireing see if anything is wrong there .I'll let use know how we get on.Still cant find the origanal coil that i took out to put the bosch GT 40 in,i think thats what it is anyway..
