Has not happened to me but if you review old starter relay threads, there are a number of posts about the starter relay remaining engaged, keeping the starter engaged (I presume) and turning at engine rpm (claimed). So many that an LED kit was created that turns on when relay powers starter side and then should go off when you let go of the key. If the LED remains on, then the starter is engaged. Grizz may be able to chime in as I think he had some input on those old threads. When I got my sled I went back to the beginning and read I think through the first 500 or so threads to learn the ins and outs of the Nytro. Great Intel back there. I suspect you are also correct if the starter clutch had an issue you would not need power from relay to keep things engaged.The only way the starter can turn at engine rpms would be if the one way starter clutch was siezed / stuck.
