I just purchased a mth c-liner (20-2414). It has PS2 and uses a 5v board. I'm having 2 problems - (1) the slave unit automatically goes into reverse whether or not it is tethered to the lead unit and (2) the lead unit is locked in neutral. The sound, bell and horn functions works fine. I've tried a reset with no success. I've also installed a new battery. Any ideas on what the problem could be? Thanks for your help.

The slave board has a shorted motor FET, that can be repaired.
When you apply power to just the lead engine, then turn power off, does the unit play shutdown sounds? If not the battery, wiring, or PS-2 board circuit is bad. That is why engine won't move in conventional.
If it plays shutdown sounds, have you done a unlock and conventional reset with the Bell/whistle buttons. You will get confirming toots. Read your instruction manual on how to unlock.
I can repair your slave board. E-mail in profile. G
