wigwag is name for fwd/reverse selector, a center stable 5k pot, 35 deg sweep each way to fsd. The stabilizing spring is far too strong for my weak fingers.
 
This is the circuit diagram of a 3 LED bar graph type battery monitor circuit Can u plz recommend a similar voltage level indicator circuit for a 24v battery bank a high and low power circuit short together – the low power cable gets so hot.

sydney,
yes, that's what happens. remove short and hope wiring ok. cct may be ok iff the supply wires were shorted. i don't know what is between my shorted wires and the battery, but as its a non runner, something has been damaged. i'm here to find out what so i know how to fix it.
