I have a problem with a decoder I have installed. I am wondering if it is defunk or what. I have full speed forward but very little in reverse. Can anyone help me with this? every other function seemsd fine except reverse.
All that reversing direction should do is chang polarity to the motor, it shouldnt have any affect on the voltage. But, stranger things have happened, so try a different decoder. If the problem still occours, make sure you brok in the loco in BOTH directions.
Thought the same thing Did brakein loco both directions. When put in reverse it just goes realy slowwww.
If the decoder has a reset option - try that, reset it to factory defaults and run it as address 03 and see what happens. If it still exhibits the symptoms, it’s probbaly defective. If one of the 4 transistors in the H-bridge motor driver on the decoder fails, it will act as described, because in one direction it will only get power on half the waveform. Depending on the motor, it might buzz a bit in the ‘bad’ direction.

Thanks does just that
