Electrical

Here's a strange one. I've soldered together a magneto timing light with a 3,5 mm audio jack for a headphone and an NE555 IC in it that generates the sound. Naming that component indicates I know about this stuff, but I don't really...

I was looking a spare to replace the Cam ring in my auto-advance magneto to rebuild it.
Anyone can address me to good source of spares?

Hello All,

"People say" spark plug polarity is important.  But:

1) Why?  If the spark is at say 10,000 volts, why should adding or subtracting 12 volts matter?

Is it possible to buy new rubber seals, grub screws etc? 
Mine vibrated off today - luckily fell into the space behind the headlight so was able to refit once I found an Allen key that fitted. However the rubber seal is really brittle.

Does anybody know why an ignition coil gets hot. 
I was running my Dominator just off the battery, and it got really warm, it's a MA12coil 12v battery.
Also does anybody know what i can do to fix this.

Need a pair for my old girl which runs 12v twin coil.  So a pair of lb05f 5ohm caps about 14" long.  All I can find is kits or bits to make them up myself - never done this and don't really want to start now.
