So, I'm British living in Tennessee. SO options are somewhat limited. The car is UK built, RHD, '75 - 78 UK, then spent 1978 approx to 2010 approx in Western or Northern Territory. Australia, then somehow came to USA.

My alternator died yesterday. I tested the battery with engine on and off and I get 12.6 volts. I know I got more before as I calibrated my centre dash Smiths Voltmeter this year. The garage also was indicator something was wrong!

So, I took it off, cleaned connectors / connections - re-installed. Still dead.
Took it apart, it's an old (not 1975!) Lucas unit, that was refurbished - but I have NO IDEA when.

Wires all look good. I open the Alternator and it was pretty crusty, almost looks cooked inside. Magnets were OK, but copper was worn. Winding looks fragile. Might had had ventilation issues in past as I had to clean A LOT of mud from engine bay / chassis. Otherwise I don;t know why it would be to bad.

SO: Question, Do I go for a 40amp BritPart (eBay) and presumably NOT bother with wire improvement OR RoversNorth 70amp and run a new Alt-BAT (Solenoid) line?

(I do NOT have any extra electrics, like Spots or Radio or anything really.)

OR is there another option?

EBAY

ROVERSNORTH

I polished all the old hardware for new one; try to keep it OEM as possible.

If 70AMP - is it easy to run that new wire, I have little experience in this. I am assuming just the correct gauge from Alt to Solenoid will do it and ZipTie it to existing Loom?

Thanks chaps

Max

Have you the manual, the green bible? It's for very detailed testing for the alternator.

I'd go for the cheapest, no extra load, so why waste money?
