Something is wrong with the one on the 7410.. It keeps tripping the circut.. Don't know why. The one on the feed wagon tractor is fine.. The skidsteer almost never needs on and I keep meaning to put one on but I keep procrastinating about it.. Came back and bit me in the arse this year... Usually hthe 7410, if plugged in will start right up... Batteries are getting old in that stinker to.. Everyting is starting to go, will probably trade her in on a newer one soon but I really, really don't want the debt.
