Coil Gremlins
Posted: Fri Sep 01, 2006 8:56 am
Maybe you guys have an idea:
One of my Sixes was running poorly and I found cold headers on 2 and 5. Quick diagnosis showed a sometimes very weak, sometimes non-existing spark on 2 and 5. As I still had a set of new, never installed Accels lying around, I decided to replace the coils. I also invested in six new plugs.
First try, bike runs like a charm. Take it to work for 15 miles, runs excellent in the morning. Park it and when I start it at lunch it runs poorly again. take it home and find headers 2 and 5 cold. Going over all wiring and connections and do some ignition checking, everything seems O.K.
Next thing, is checking the coils and I find the primary winding on coil 2/5 shows zero conductivity. Question: is this just a coincidence or is there something that can make the coil go kaputt?
I really hate electrical stuff.
