The right mag is having a persistent drop of about 800 rpm running rough and the engine is even quitting (when mag switch is in right mag only) I have an elderly engine with the A module on top.( 180 hrs tt) When I wiggle the 4 pole plug receptacle and the red power wire then I will get my mag back for a little while (until I start it again and do the runup then it will misfire again. I have stripped back the short black wire protective cover at the module and have slit open three of the wires I found "kinked" expecting to find breaks but they were all intact. This morning I am going to reinstall the plug and try trouble shooting the red module power wires.I have already replaced the "p" leads and the mag switch.( they check good with an ohmeter) Is there any way to test the wires for a break (or breaks) without running the engine? Electric's are my absolute weakest area and I am having a real struggle with this. Any ideas? Am I going down the right trail?

From: "rampil" TCP and Decalin render the lead soft and pasty but not soluble. 100LL burned without these products produces harder, crusty lead which is harder to clean off plugs and valves. The crusty lead now at the bottom of your crankcase is now there until you scrape it off (good luck!), but will probably not harm anything by its presence. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p 6101#206101 ________________________________ Message 6 _____________________________________ Time: 06:01:27 PM PST US Subject: RotaxEngines-List: Re: Bad mag check 912UL From: "Roger Lee" Hi Dick, You can do an ohm meter check through the wires from the coils to just before to module. This will tell you if the coils are ok. I don't have a manual handy so I don't know what the values are. This doen't sound like a coil problem. Is your engine old enough to have just one ignition module? It sounds like it could be a bad wire in the plug socket just before the module. IF you can wiggle the wires and they work then you most likely just have a bad connection and possibly in the socket. At an 800 rpm drop you are losing one complete ignition bank or 4 plugs. You can get an AC power tester for about $12 and since the plugs produce AC power the tester will show you which wires from the ignition coils to the plugs are firing and which are not. Picture attached. This tester can also find bad plugs and plug wires if you are only dropping 300 rpm. You just need to get the tester near the wire or touch the wire. If the module is bad wiggling the wires should not help. That's why I think it is just a bad connection since you can wiggle the wire and make it work until vibration loosens the connection again. -------- Roger Lee Tucson, Az.
