Need help with a reset PS2

I would check the battery here, and replace it. Since it’s new/old stock it’s been sitting for quite some time. Since it was released in 2008, you’re looking at a battery that is 17 years old. Good luck and please report back-

I have a BCR that I will try tomorrow and let you know. When it was working it would stay alive for about 10 seconds after power was off and even when it was on my programing track  in Conventional mode.

I found a few minutes tonight and replaced the battery with a BCR and no difference. I made sure the harness was in place and seated.

If the sound drops immediately after killing power and you've allowed the BCR at least several minutes to charge with power on, the charging circuit on the board probably has a problem.

The sound stays on after the power is off until the shut down sound sequence is complet. It did that before I changed the battery and it is that way with the BCR too.

If you never heard the whistle in conventional mode, I doubt the reset procedure worked.

What transformer are you using to do the conventional reset?

Do you have another locomotive to test with that transformer and make sure your whistle button is working correctly?
