I recently bought a MTH F40PH w/Proto 1 that was converted to TMCC using the equalizer board from Digital Dynamics.
I have a simular engine that I did this upgrade to about a year or so ago.
I also remember having a simular problem with it.
The Problem: No Sound!
(It runs forward & backward smoothly and both couplers work fine)
I have sucessfully set the engine ID
and presumably set the engine type.
When I power up the engine I get 2 dings AND 2 air releases.
Should now be in reset. Right?
I follow the procedure for programing protosounds with the Cab-1.
[ENG] # [AUX1]#code[AUX1] (NO ‘clanks or clinks’)[BELL] (NO bell heard)
Shut down, wait 15 sec., power up, address eng. [AUX1] 0 (moves but no sounds)
If Pat will let me go out on a limb here… Hes running TMCC. But you do not need to ‘start up’ a TMCC loco, like you do the MTH proto 2, you can blow the horn on a Lionel and it will be ready to roll
It appears you shut off the engine volume before you put in in the DD board. Position 6 sets the engine volume but I believe has to be done when still in a proto one board.
Try doing six and pu***he whistle button if it gives you sound it works in the DD board.
