Need some help here. My tractor started acting up when starting. Same symptons as many I've read on here; rapid clicking of starter, sometimes nothing at all. Sometimes it seemed that the clutch safety switch was the issue but not consistent. The other day, same issues. When starter finally started engaged, it took a while to start. After moving a couple of hundred yards, I smelled something (electrical) burning. Turned the switch off and to my surprise the bendix was still engaged! Turned switch back on and tractor would run. Turned switch off again, grabbed a pair of pliers and disconnected the battery. By this time, the bendix had turned into a blue smoke generator. There were also some burning of the connectors on the starter. Ordered new starter and replaced it. When I went to hook up the battery, the starter engaged with the switch off. Did continuity checks on switch assembly and all checks out. Same for clutch safety switch. There is a dead short between the bendix wire and the hot side of the battery. My next guess would be the starter relay. Another ideas? Appreciate any and all comments.
