Wiring for mechanical reversing switch (golf car type)
As shown in Figure 7, this type of switch mechanically interchanges the two
motor field cables by rotating a movable contact bar. The configuration shown
is typical; many variations are in use.
Throttle Wiring
Ten throttle types can be used with these controllers:
Type 0 2-wire potentiometer, 0–5kΩ
Type 1 2-wire potentiometer, 5kΩ–0
Type 2 single-ended 0–5V input
Type 3 2-wire potentiometer, 4.6kΩ–0
Type 4 2-wire potentiometer, 5.5kΩ–0
Type 5 2-wire potentiometer, 1kΩ–0
Type 6 ITS input
Type 7 single-ended 6.3–10.6 V input
Type 8 single-ended 6–12 V input
Type 9 single-ended 3-wire potentiometer, 0–5kΩ
Throttle Type 0
Wiring for Type 0 throttles is simple: just connect the two wires to the J2 and J3
push-on terminals; it doesn’t matter which wire goes on which terminal. With
Type 0 throttles, resistance increases as the applied throttle is increased.

Mechanical potboxes and footpedals are Type 0 throttles. It doesn’t matter which
wire goes on which terminal, and the wires can be extended as required.
