PWM MODULE
Description
• Take voltage measurements by probing into wires near
the PWM module shown in figure [A]. All connectors
must remain plugged into their respectful harness.
• Turn the key to the ON position with the engine OFF.
• Turn the switches ON to get their appropriate readings.
(Example: Input from Proportional flow switch – Push
switch full left then full right to get the voltage readings
listed below.)
• Press the auxiliary hydraulic switch (Item 2) [B] twice.
Both Green lights will be ON. Check Wire# 9, 17, 18,
or 19.
NOTE: Item descriptions are listed below as Input to
or Output from the Module. Voltage readings
are approximate. They are affected by battery
condition (system voltage). Voltage readings
for Items 10, 18, and 19 are variable and
correspond to Proportional Flow Switch
travel.
