Hi guys
Im Bob a newbie from UK.
04. C70. 80K miles. 2000 ragtop.

Anyone know where to find alternator / battery charging data? I have seen a lot of data but not in simple english.
history of problem.
New battery 6 months ago (AA said it was knackered)
1 or 2 flat batteries since.
last night no start again, AA put volt meter on battery only & said 11 volts, its yer alternator.
No warning lights, checked voltages today myself, at 3k revs battery shows 13.16, Alternator shows 13.23 is this ok or low?
Battery + lug was loose & the B+ cable snapped easily at the terminal.
removed said cable tested fine so soldered new end on.
readings at battery & alternator are the same as b4.
Cant understand why it was at 11V last night,, regulator?
Only other electrical issue is the brake lights stay on sometimes, I thought this is why I had the odd flat battery. (its the switch sticking)

Why does it hammer down when I am repairing the car ? all summer no issues LMAO
