    Ok, as of today, with new fuses installed.... tiger idles fine. Soon as I ramp up the throttle, it pops the fuse and the amperes are reading off the chart like its over charging?

    27Hp Carbed Kaw engine.

    I dont really know what else to say.

    update: update: IF I jump the fuse terminal with the yellow wires going to it, the mower will run at full throttle but the amperes gauge pegs out on +. But if I put a fuse back in it and ramp the throttle up, it pops the fuse immediately.

    could a defective battery cause excessively high amper readings?

    It all kinda makes sense now in a way.... so seems my machine is (overcharging?) and since it is... after about the usual 40mins of mowing, maybe the elec. system is overly hot and shuts down my machine.? I hate electrical issues.


    Where is the voltage regulator on it?

    That is the voltage regulator in the pic, I suspect that's the problem. I don't recall a bad battery causing a over charge situation to the point of blowing fuses. There is a test procedure for the regulator but I need the engine numbers to assure I post the proper test.


    Look on the engine BLOCK near the starter or oil dipstick areas for this white bar code label.....
