right then.

Took the rec / reg off this morning, looks fine....no corrosion or damage. the plug also looks fine. before my scotland trip i had taken it apart, covered in ACF50 and made a little cover out of an old mountain bike innner tube to go around the plug.

i charged my battery and popped it back in.

With the ignition off the battery said 12.74
started bike, let iddle for 5 secs and it was 13.86v
left it for 8 -10 secs, now said 13.89v
reved it and the voltage dropped RIGHT down, couldnt read it as it was just falling numbers.
now its iddling again its reading 12v
revved again, same thing - major falling voltage.

SO....am i right to assume the actually reg/rec is knackered? also is the plug supposed to "clip" into the top of the unit? mine doesnt...it just pushes down on and then stops...no click feeling if you know what i mean.

also forgot to mention that when i pulled over due to this problem i could smell burning from engine. saying that though i had been riding all day at 75mph.

Talking off riding all day...i also noticed how quick the oil breather fills up. 2 to 3 days of all day riding (on road at 70mph ish) and it was full, is this normal?

any advice welcome as i now ****** all about elecs!
