If the voltage regulator sticks (cutout points can weld together) the wire going from the starter switch to the amp gauge, and those from the amp gauge to the regulator, and from the regulator to the generator, and the generator itself can burn up. All those wires and all those components are now suspect of being toast. If the starter motor Frame (metal) was hot it is also possibly toast. Disconnect the battery !!

Then connect remove the big wire from the starter switch and make sure it touches nothing. Put the battery terminal back on. Use the loose end of the cable to touch the start switch. If it sparks, do not attach. If the test light lights up. Do not attach it. The regulator might be shorted. disconnect the Arm wire from the gen and keep it from touching anything it the test light stays out it is pretty certain the regulator has welded cutout contacts inside.
