Hi Guys. Tried to search posts and couldn't find info. on this one. I walked up to my tractor one day and my Lift pump was running, No key in the Ignition ,switch in off position, Started it up used it then it wouldn't shutoff. Killed the engine manually ,electric pump still running,pulled neg. bat. cable left it. Came Back a few days later put cable back on used the tractor , parked it, turned key to off position worked as it should everything off. Came back 20min. later no key in ignition pump is running and batt. light is on . What the ****? Has anyone had this experience? Thanks in advance Paul
