ELECTRICAL SYSTEM
Err06
Brush lift actuator open circuit (**)
Check for disconnected actuator wiring, open in wiring
or defective actuator motor. Repair or replace.
Err07
Brush motor overload
Check for binding in rotation of brushes or improper
brush lift actuator operation. 2. Check the negative
supply cable at the brush motor for a wiring problem or
improper modifications (this is a special cable and
must be replaced with the original OEM PN 56412181).
Err08
Brush motor severe overload
1. Check for short circuit in brush motor or wiring. 2.
Inspect gearbox for failure. Repair or replace.
Err09
Brush motor circuit open (**)
1. Check for open in brush motor wiring or defective
motor. 2. Check the negative supply cable at the brush
motor for a wiring problem or improper modifications
(this is a special cable and must be replaced with the
original OEM PN 56412181).
Err10
Brush solenoid contacts shorted
Check solenoid for welded contacts (continuity test). If
welded replace solenoid.
Err12
Brush solenoid coil overload
1. Check diode for continuity in one direction only, if
bad, replace diode. 2. Check for proper installation of
diode (silver band is wired to positive side of coil) 3.
Check for wiring problems. 4. Check coil resistance if
below 41 ohms replace solenoid.
Err13
Brush solenoid coil severe overload
1. Same as error code 12. 2. Shorted coil. Replace
Err14
Brush solenoid coil open (**)
1. Check for an open in the coil wiring 2. Check solenoid
coil for high resistance (infinity). Repair or replace.
Err15
Brush current too high
1. Check for proper brush lift actuator operation (actua-
tor linkage). 2.Check for free rotation of brush drive
assembly.
Err16
Brush current too low
1. Check for improper, too low brush pressure (see
brush pressure adjustment section). 2. No brushes
installed 3. Check proper brush lift actuator operation.
Err17
Brush motor cable thermistor failure
Machine exposed to a very cold or hot operating
temperature. Allow machine to be warmed or cooled to
room temperature. Temp range 56°F to 180°F (13 to
82°C) 2. Cable failure, replace the brush motor nega-
tive cable assemble (this is a special cable and must be
replaced with an original OEM PN 56412181).
