Just pulled out the 700 and light keeps flashing 7 times over and over. Power vales are free and clean...PV motor goes back to home position if i turn it by hand....sometimes when I choke it to try to get it to move under 900 rpm it does and somtimes does nothing....wiring looks good..???? The light did stop after riding a bit but now its back....sled runs like a top....but the light must mean somthing....any idea's...thanks
