Hi,

After you replaced the batteries did you perform a manual battery test?

If not do so.

You will need new igniton cylinder. Sounds like you have a short in the cylinder.

I usually fix electrical problems by process of elimination. Disconnect the wires attached to generator and touch the battery cable to the battery if it still arcs disconnect the regulator. continue until you find whats pulling current from the battery.

sound slike you may have unplugged or disconnected somethine else or the spark plug you put in is bad or inpropper gap
