(no sound) horn and bell work. any other ideas or what am I doing wrong in the sequence. Thanks for the help so far. I had my fingers crossed.
I didn't really understand the first part of what you said: To properly do a reset you need to power up before the engine completely shuts down. (is this with the reset chip in?) You have not executed the reset. After you hit the program button, raise the throttles before 3 seconds. (I did try this too but with reset chip in nothing happens at all)

First thing I do with a new chip is power up conventionally and let the engine start up. This can take 3-5 seconds with a new chip as software is processed. Then lower to 10Vs for the direction change. Everything should work fine.
If not, then do the Reset 18, but you must cycle power to get the engine out of reset and into an operating state (fwd).
I believe this model was succeptable to ID conflict. The new chip should have resolved it. There is a Tech chip to reset these boards if it still has issues. G
