FAULT FINDING
Symptom
Possible Causes
No Power
– no lights
on True Charge
o
Check batteries are charged
o
Check battery conn battery key switch and ignition toggle switch are both on
o
Check all the battery leads, controller conne handset wiring plugs
True Charge meter
lights up but no power
to motors
o
Make sure deadmans switch is applied
o
Check wire connections in handset, plug, socket and plug on iDrive
– see wiring
diagram
TrueCharge meter just
flashes
o
See fault code chart. Switch off by ignition switch for 30 seconds before switching on
o
If possible, rectify fault shown on chart
TrueCharge doesn’t
show green lights
o
The TrueCharge Meter reads the voltage from the batteries. Some batteries can give a
slightly lower voltage and yet still provide the capacity required.
Engine seems to be
losing power
o
Gears are pinned on the motors so unlikely to be slipping but could be a motor slipping
out of mesh. Check and reset meshing
o
Check to see if Truecharge Meter drops when power applied if yes - failing batteries
o
Grease on track. This will affect acceleration and regenerative braking. This is more
common than you may think. Clean track and wheels to cure.
Strange whirring
sounds coming from
under loco
o
STOP IMMEDIATELY. Check for meshed gears and trapped debris
o
Oil all oilite bearings and Delrin boxes on cranked locos
Acceleration and
deceleration is “lumpy”
o
This could be a symptom of a faulty or failing potentiometer in the handset. Replace the
5k linear potentiometer if in doubt.
o
Grease on the track
– clean track
Electrical smell coming
from the engine
o
Switch off the power immediately by the battery isolator switch.
o
Investigate using smell and touch for hot wires and components. Report back to RoR
o
The controller is rated for 120amp continuous running. Do not over load the loco as it
can result in damaging the motor wires and overheating of the motors. If in doubt check
motor temperature regularly by reaching under the loco and feeling the motors.
