Hi Steve,

Thank you for posting that nice clear colour diagram; I've wired it in but still doesn't light up the warning light.

Cheers

If you could take it apart and look inside you would not be surprised that it doesn't work. They are pretty crude which is probably why it doesn't work. There are better alternatives available. Alan Osbourn does a charging monitor and other places do similar things.

I also had the problem of the ignition light not lighting up. After a few miles it started behaving properly but still occasionally refuses. Charging is always OK, though, as is the spark.

dont know if this will help

My Mk3 850 assimilator does the same - sometimes works normally with red light coming on when ignition switched on then goes out when engine fires up (and flickers a bit if enginetickover revs get too slow),while other times red warning light doesn't come on at all when ignition switched on.

Earlier round metal case assimilator fitted to 750 and early 850 Commandos seemed to work better. Have this one on my Mk1a 850 which has never given trouble in 53 years (with original warning light bulb still in place) !
