I keep blowing out this J20's ignition coils. This time around, the cap on the coil was almost lifted off, so I am back ordering a replacement. I am wondering if adding a ballast resistor would alleviate this problem. The trencher has an old Wisconsin air-cooled Engine, and finding original electrical parts for it is not possible. Since it has what appears to be an old Ford transmission, I think I'll try to order a Forn 9N coil. I read somewhere that a ballast resistor will prolong the life of breaker points and I am wondering if it will also help the coil as well.
