V-Twin Coil

Cory,

I can't tell much about the inside of the coil because of the epoxy. I pried off the shell and the epoxy has cracks in it, but I might have done it while prying.


About 15 years ago, I trailered a bike to Daytona, and the repop coil got sprayed with road salt. It lasted about 5 miles after that. They definitely aren't very moisture resistant.

Thanks Tim,

I think I'll make an attempt at sealing the one I have up before water finds it's way in. The last one saw more than one giant rainstorm.

Sealing is probably a good idea, I certainly had something going on with mine after it had gotten wet, I think I will also look at running some silicon around the joints.

Bob,

I'm glad this "sealing" thing came up as I may have risked having problems on the road again this summer. I always enjoy my tours but seem to find at least one downpour enroute...

If we are talking magneto double coils here, the plugs both fire together, one being compression, one is at exhaust, both same direction. Here a easy way to check intensity without tools. Make a jig/rig like this and fix it 1/4" from mag body and kick. Should see a blue spark jump, if not, setup has a problem.

If ignition coils, whole different story, as I learned very recently. I think the two are getting crossed up here! Just my 2 cents.
