Brent, I still cannot find my way properly around the new web site. For example I cannot find Ruedi Bruegger's excellent tuning pot circuit and software that I have built and use, nor the rev limiter circuit from David Withers that I also use. I think they were both in contributed files or something...

Relays can cope with 100-200 V. If you get one with contacts rated at 240 VAC it will withstand up to 240*1.414=340V. The current would be less than 2 amps. It would be best not to get a very small physical size relay - typical auto size should be OK. It would need a pole (separate pair of contacts)...

re: http://picasso.org/mjlj/?q=node/469 I made some comments including whether the thyristor properties are needed. It looks to me that using a relay to connect the coil to ground through a resistor of say 8 ohms (I use 12) to inhibit the spark would work. I cannot see how switching the relay on or ...

Robert, I used a diode I found in the scrap box which was a 1n4005 (1amp 600V) but a 1N4001 would do (1 amp 50V) or 4002,4003,4004. It just has to withstand the alternator reverse voltage of around 20V max and take the lamp current which is probably a good deal less than 1 amp. It is a few mm long a...

My megajolt worked fine when I wired it up temporarily, but when I wired it in properly it overran, and would have carried on idling indefinitely if I hadn't stopped by engaging gear and letting the clutch in. I noticed: a) a red power indicator light that I put on the Megajolt was glowing much weak...
