Slickstart wiring??

[Immelman]

A favor to ask - could anyone with a slickstart send me a few photos of the wiring at the magneto, and bonus points if you could tell me if the lead that goes from slickstart to P-lead is shielded or not? Could you also let me know, if if your starting mag had a retard breaker, if you know whether the lead from the retard breaker still goes to the ignition switch, or only to the slick start??

I have a slickstart in me E. The engine has become progressively harder to start over the past several months. In troubleshooting I found that the slickstart was apparently not functioning, so I began to plan a surefly sim installation, but I thought I should give the whole slickstart install a once over. Lo and behold... it is wired up differently than in the manual, likely an older (original) setup where the slickstart energy was routed through the ignition switch. Champion says don't do that anymore. I disconnected things and tried slickstart jumpered to the mag per the instructions and it works! What a mystery.... was it ever wired up right? Did some hangar elf disconnect something in the past? Its time to make it right.

see if this can get you any closer...

It shows some MSers have some knowledge of the system...

Thanks carusoam... this is one of those tricky situations. Original slickstart instructions (that I do not have) said one thing. Champion changed the instructions to now say something different.. airplane looks like its not wired right for either.

The slick start and the shower of sparks, both work when the points are open. The ignition switch connects both points in parallel to start and turns on the shower of sparks. That way the mag doesn't see a point opening until they both open, which is at the retarded (~TDC) timing. The shower of sparks charges the primary of the mag because there isn't enough energy from the spinning magnet to fire the mag reliably. The output from the slick start could be a separate wire that is put on the retard lead on the mag, or the original retard P lead can be routed to the Slick Start. Shielded wires are typical. Your mags don't care about the shielding, but you may get radio noise.

Rich, thank you.

I looked at things closely this evening. It all makes sense.

During my overhaul, I am switching from Bendix mags to Slicks, already had a Slickstart, but had to get a new one compatible with the Slick mags.  I have all of current installation instructions, the Slickstart I removed was wired the “old” way.  I can scan and send you a copy if you would like, pm me if interested.  Still waiting on Lycoming narrow deck cylinders..

Keith,

Thank you.. I may take you up on that if things dont work out here... but for now I think I have it sorted out. I will send you a pm if I need the 'old way'.
