Just starting to learn about the electrical side of things and though the vast knowledge here would help. My stove was idling well for about 20 min then suddenly ran rough for a minute and stalled. After sitting for 6 hours the coil was still almost too hot to touch. It has been converted to 12v but I don't know if the coil was changed. It doesn't any indication of voltage on the coil. What I do know, it has a new 12v battery and has an old ballast resistor. The starter was changed and the coil was wired back to the R screw which just grounded it and caused the ballast resistor to get hot. Not sure if it is bad or if the coil is bad or not the correct voltage. I bough a new 12v coil but haven't installed it yet. Any thoughts would be greatly appreciated. Thanks.
