I recently bought my first ERR product. A mini commander ACC to add TMCC to an MTH Tropicana reefer. Unfortunately I have been unable to get it to work even though the wiring looks correct (I've rechecked it several times) and the board does get 18V.
I sent an email to 3d Rail over a week ago but have not gotten a response. Is there a phone number I can call so speak to someone?
