Hello, I have a difficult problem with my Sporty; My starter only turns the engine when I have turned the spark plugs out,as if the starter engine no longer has any power. But it is absolutely no BATTERY PROBLEM! When I start a few seconds the starter cables are so hot that it smears the plastic jacket. I tested the starter directly on a battery even in the developed condition, it seems to work normally, but here too the cable nac h a few seconds already warm.Can that be normal?
