TROUBLESHOOTING GUIDE

Possible Symptom

All the machine accessory system’s functions (operations) do not work. Example: no brush, broom, vacuum and hopper functions etc.

Part A: Electrical Control Circuit

Note: Do all testing with Key Switch ON.

All the machine accessory

system’s functions

(operations) do not work

When key is first turned

on do all the A2 display

panel lights momentarily

turn on?

Test for the 12V output from

A1 wires WHT/BRN & BLK

Check the power & commu-

nication inputs to A2

•

Test circuit continuity of

wires BRN/BLU & GRN/BLU

•

Test for 12V power input

wires WHT/BRN & BLK

Sub a new A2 Display Panel

Machine system fixed all

functions now operational

See Hydraulic Load Circuit

Part B

Repair or replace

defective wiring

Replace A1 Main

Controller

Test for the 12V power

input to A1, wires VIO &

BLK

•

Check for a defective F2

circuit breaker (15A)

•

An open in either the circuit

battery (pos.) VIO wire or BLK

battery (neg.) wire

Repair or replace defective

parts.

Do the A2 panel lights now

function?

Yes

Replace the A1 Controller

Yes
