I loaned out ( with reservation ) My 743B when I went to pick it up he said it has been having a dead battery and hasnt moved for several days. The key would not do anything, no solenoid click or starter. I jumpered a pair of wires that are randomly hanging in the wiring harness near the starter to the main power pole of the starter. it immediately activated the solonoid and I was able to start it using the key. The real problem here is that the key wont turn the bobcat off, I have to leave it jumpered to run and it wont shut off until I undo the jumper. Is there a realy that activates the solonoid? or do I have other electrical issues?
