Indecently its also on the 3rd crankshaft pick up, this one is a rewind done by west country windings out of better insulated wire, so seems to be lasting a bit longer.

Bad earth(s), alternator overcharging/dodgy voltage regulator, leaking HT leads/plug caps, plug gaps too big (unlikely but I'm out of ideas now). -- Si '88 XV535, '82 XJ550 being fettled.
