i had , what i thought was a parasitic drain on the battery to find out it was a stuffed battery. the issue started with the flat battery the day after using the car, so i charged the battery and then went back after it sat for three days to find another flat battery. as i hadn't connected the battery, it was obvious what was happening, off to the shop , new battery and all good, no that's not how it works. we all know that nothing is that simple, after connecting up the new battery i decided to just check that the alternator was working and yes it was working, it was working to much actually, charging at 16.9volts," i think this is the reason for the battery dying " even i know that's not right. now the real issue, i have 3 spare alternators or should i say had. the issue with the alternators is the brushes, and the bearings, but that's another day,
where the brushes rub on the rotor in the alternator on the brass piece on the shaft had very large grooves on the outside brush, this was on 2 of the alternators and that brush had all but worn away, whilst the other was fine. is this piece replaceable or is it the hole rotor that has to be replaced, also is the regulator still available as i don't seem to be able to find them in Australia. so as a warning if you have alternators as spares remove the back cover and visually look at the brushes and the area that they contact.
