My Big Hauler sound card makes a strange burp noise rather than a chuff noise. It is an older version without the volume control knob. Looking for ideas on what to check. I have verified that the problem is in the tender and not the locomotive. I had another one that did the same thing but it had a visibly damaged (leaking) capacitor. Changing that fixed it. Any thoughts will be greatly appreciated.

Thanks G gauge, I have read that before & it seems to be more about improving the card than trouble shooting problems. However I think I will try adding those capacitors & see what happens. Won't hurt---might fix it!
Thanks again
If i remember correctly the burp can also come from the cam in the engine that controles the chuff. There was a problem with the contact hitting the wheels picking up excess cu-rent. Installing a spacer or washer took care of it.

Thanks for the input I really appreciate it. This thing makes the same noise if the contacts are shorted at the connector. It seemed to get a little worse each time it was run. By the way, the locomotive is battery operated with no power to the rails. Thanks again.
