I recently acquired a Weaver 3-Rail Union Pacific 49er that was new in box according to the seller. The engine does run but I get weird behavior with the sounds (has the OG QSI sound package):
- When running the chugging sounds act like it wants to start but ends up being a speaker blip
- In neutral the sounds work at a higher voltage on the controller (using Z-1000 controller)
- Whistle will cut off at lower voltage when starting, works okay at higher voltage (bell works)
I popped the top and discovered it has a battery similar to the PS-1 and PS-2 locomotives (photo attached). I've got my controller hooked up and will let it attempt to charge over night. Could the erratic sound behavior be the result of the battery voltage being too low? If it does need to be replaced is there a favorite one that folks recommend? I have heard about a BCR but I've seen conflicting information on whether or not it works with the QSI sound system which was a predecessor to PS1. I can see where the speaker is hooked up so can pull the plug on that as a poor mans way of disabling the sound (would unplugging the battery do the same thing?)
Thanks in advance for any help!
