4.0 General Decoder Troubleshooting

4.1 The decoder won’t respond

Make sure track power is ON

If the throttle is indicating that track power is off, turn track power on.

Can you control the functions but not the motor?

If so, remove the loco from the track and check your installation for motor iso-

lation or short circuit problems.

Can’t select the loco address on your throttle

1. If you see STEAL=Y? or stL? on your throttle display, the loco is

in use by another throttle. Release the loco from the other throttle

before proceeding.

2. If you see consist or cn, the loco is part of a consist and can’t be

selected individually. Remove the loco from the consist before con-

tinuing

Check the value programmed into CV29

If your decoder is a 14 step decoder running on a system that is sending 28/128

speed step commands, status editing is necessary to make the commands sent

by the system match what the decoder can handle.

Have you reset any CVs since the last time you ran the loco?

If so, go back and change them to their default values and then try to run the

loco. It is possible to set acceleration so high that it will take 10 minutes for the

loco to start moving.

Does your throttle say slot=max or FuLL?

This means that the system’s capacity to handle operating locos is full. If you

have the slot=max or FuLL message, be sure that all locos that are not running

are released from throttles. Check your command station manual to determine

how many locos your system can handle at a time.

During decoder programming, slot=max or FuLL message will be displayed if

the loco you are trying to program has too many current loads attached. If this

is the case, you need to remove some of the extra loads to program the decoder.

This happens with locos that have many lamps installed or where the lamps are

wired directly to the track pickups.

If all else fails, reprogram the decoder’s address and reset CVs to default

values by setting CV08 to 08 to reset everything or to 09 to reset every-

thing except loadable speed table and sound project selection entries.
