DIAGNOSTIC METHOD - FIND THE PROBLEM....FAST!

Using the diagram below and a test light, activate each function and test the corresponding pin in the Harness

Plug for power. For Lift, Left Angle & Right Angle functions, the Pin for each function AND the Pin for the Pump

Solenoid should be powered at the same time. Activating the Pump Solenoid will also power the 12vdc Hi-Amp

Pin (#2). When testing the float function, only that Pin will be powered. For testing Headlight and Directional

functions, it will be necessary to turn each function on inside the cab. If all Pins test correctly, the Vehicle Harness

System has been eliminated as the cause of the malfunction. If one or more Pins do not test correctly, determine

which device is connected at the other end of the Harness.

For function problems, test the In-Cab Controls. To do this, attach the test light alligator clip to ground and insert the

probe of the test light into the colored wire on the in-cab control that corresponds with the function that is being

tested. Activate the function and test for power. Through the process of elimination, the In-Cab Control will be

determined faulty or in good working order.

The very first step in this process is to verify a PROPER INSTALLATION i.e. In-Cab Control plugged in and turned

on, all wires connected correctly, good ground connections, etc...

The starting point for this method is the Vehicle Side Electrical System. The chart below details all of the Plug

Pinouts for the Vehicle Side Harness.
