Reply to BOBBY's Post: WHEN I RUN THE ENGINE THE BATTERY DIES. IF I TAKE A TEN MINUTE RIDE WHEN I COME BACK AND TURN OFF THE ENGINE IT WILL NOT RESTART. I CHARGE THE BATTERY WITH A CHARGER THE ENGINE STARTS RIGHT UP. I CHANGED THE ALTERNATOR AND THE BATTERY. I ALSO CLEANED ALL WIRES. THE BATTERY STILL GOES DEAD.

Do you happen to know the voltage at the battery terminals when the engine is running?
