I just purchased a Weaver U25B (circa 1998) that has a QSI sound system. It is new in the box and has never been run. I have no layout and I am using a postwar Lionel ZW transformer with a Lionel 5906 sound activation button on a section of test track. The locomotive functions fine in both forward and reverse, the lighting is working perfectly as designed, the sound system activates according to specification and sounds great. The bell also functions properly. However when I try to activate the horn it does not work. While engaging the horn by sliding the lever forward the locomotive speed up and stays that way until I release it and then the locomotive resumes its normal speed. By reading your forums I have discovered that the QSI sound system is a predecessor to Proto Sound 1 which I never knew. I am not sure if the loco has an internal electrical circuit board problem or if the problem is with my Lionel ZW transformer. There may be a compatibility problem between the two. Obviously I can't contact Weaver since they are now out of business, which is unfortunate since they had outstanding customer service and support. I don't want to return this locomotive since it is a very limited addition piece of 129 manufactured for NETCA's 40th anniversary (1958-1998) and it is also the only locomotive that NETCA has ever released in all of their offerings. I need your assistance in trying fix this problem please.
