 Posted: Tue Aug 16, 2011 4:48 am Post subject: Slick mag problem |
 |
|
36.4 hours on the airframe and on the mag check I had a 400 RPM drop. For some more background in the first runs with the engine after install the mag drop was about 125 RPM. As I progressed through phase 1 the mag drop got worse and I thought I was having fouled plug issues by not being able to lean (James Cowl) because following a fouled plug clearing procedure the mag drop would be back into 'acceptable' ranges. After extensive troubleshooting by myself and a couple of other mechanics we found the output of the coil to be very weak with some 'abnormal resistance' as they called it through the condenser. I called the engine manufacturer about the problem, and of course they are trying to work something, but they are merely the middle man. Anyone ever had any luck getting warranty work from the manufacturer of the Slick mags? I am supposed to be heading out on a trip next week and can't afford to be screwing around with the crap mag for awhile.

I'd replace the defective parts, keep the bad ones and receipts for all you did. Yes, it may cost you a few hundred up front, you may or may not get reimbursed, but your plane will be flying and your trip won't be ruined. If you are lucky, you will get reimbursed. IIRC I think Champion now owns Slick. I know Unison sold their aircraft product business lines to several other companies. Tempest got the spark plug business.

Kelly, that's what I was looking at doing. Just wasn't sure if there was a hot swap program with the manufacturer before laying out the couple hundred bucks. I have also been digging for repair manuals to see if the coil and condenser on the 6000 and 4000 series are the same. I have access to a brand new 4000 series mag for float parts but won't touch it until I know if the parts are compatible, but service manuals for the Slick mags are tough to come by in my neck of the woods. I am awaiting a call back from the engine manufacturer and Slick a.k.a. Champion about the issue.

I show K3975 coil for 42xx and 63xx mags, k3984 capacitor for both series.

Thanks Kelly. I now have a temporary solution for sure.
