7119 Voltage Regulator

Recommended Posts

Hey all, I have a 7119 with the original Kohler Engine in it. I have been having an issue lately that my new battery is dead everytime I go to start the tractor. I just got around to checking the voltage at the battery while the engine is at full throttle. It came in at 19 volts. This seems high, does anybody know what voltage the regulator should be set at? I don't want to go and buy a new battery if I need to replace the regulator as well. Thanks Bucky33

Best bet is just get new voltage regulator, most likely its going bad. On second though, the stator might be dirty, thats behind the flywheel, that would requrie pulling the motor out.

The voltage is definitely too high and that may have damaged the battery so it no longer holds a charge. Does the battery hold charge with one of the battery terminal wires removed? If it does, then there's a parasitic drain somewhere when the key switch is "off" slowly discharging the battery while it's sitting. With the switch "off", the "+" battery lead disconnected, the resistance from the cable end to ground should be infinite.

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
