thought maybe someone out there had an idea before i start throwing parts at it,last weekend we were out on lake red rock in central iowa,when i started my 89 comp it fired right up but the starter wouldnt disengage so i tried turning the key switch off and still nothing,i even pulled the key out and it would not shut off,so i reached under and disconnected the battery terminal so it would stop,it finally stopped so i hooked it back up and it started just fine,but it did happen again one other time.Anyway we got some great skiing,footin,wakeboardin,and tubing in before we left.any help would be greatly appreciated.Thanks.
