Hi, I studied the tutorial on youtube and tested mine, with the following results.
Using a decent enough digital multi meter; with enigine at running temperature
Engine off and no electrics on = 13.25V
Engine on and no electrics on = 14.25V
Still engine running, with full beam, hazards, radio and wipers on full = 12.85V
Engine switched off and electric items all off = 12.90V
I then did the 'voltage drop test' as described in the video and there was no problem there.
But with those readings, am I looking at a weak or dying alternator.
Thanks alot for any help
