Well the mystery has been solved after working in the rain on Thursday to trace out the problem I read all the advice and started out Friday, by first checking the switches in the back the engine run switch was in the off position, mmm. turned switch on, I bet you all know where this is going by now. Start the bus from the drivers area. Bus runs amazing, what I did wrong. Goes back to wensday when I changed the oil I started the bus from the rear position to be there if anything went wrong with oil leaks or pressure. Let it run then shut It down test level then I left for the day. Went back on Thursday to move the bus problem started left switch in off position from the previous day . Now what is really stupid is I even had the back remote box off testing wires and did not even notice the switch was off!!! My Sincere Appreciation to every one that help me through this problem.
It is not a real good idea to shut down the engine by using the emergency shut down switch or manual lever. It is far better to do it with the engine off and the run switch on.
