[QUOTE="oexing, post: 172651, member: 1493"] Erik, you want capacitors tolerating AC current in magnets, unlike coil ignition with one positive end on coil never changing in rotation. So the "selfhealing" WIMA MKP types will do the job. You look for max. AC rating like 1000 V but the size is your limit in the old mags with rotating coil. So 0,22 myF and ca. 630 V AC will do, higher AC voltage types will be too big. To be open, I don´t have much faith in cool fancy caps from the bikers´scene as I don´t expect them to be robust enough at high AC voltages in the long run, seeing the very small sizes of these.
