INote To avoid damaging components or troubleshooting equipment, disconnect the battery cables before proceeding
1Remove the steering housing cover
2Turn speed control switch to OFF3Use an ohmmeter calibrated on low ohms scale to test the condition of the resistor assembly and motor tube wiring
rn andConnect the ohmmeter between the terminalsterminals 5with the RED GREEN leads (terminals "1" and "2", 12 Volt,
4The terminal numbers and their locations on the speed control switch are as shown (terminal side of switch)
"2" and "4", 24 Volt): The meter should show 0.18-0.22 ohm resistance If measured resistance is significantly different and motor does not respond to speed control change, replace resistor
