New old Williams horn problem

[Garfield]

I bought a set of Williams F7 (1 powered one dummy).
They were still sealed in plastic and I bet they are at least 10 years old.

The horn in the powered unit does not work. It clicks and pops like you are running straight D.C. to the speaker. I tried a different speaker and it did the same thing. It is not a constant noise you only get one click and then a pop.

I tried it with a CW 80 and a K Line Power Chief.
I tried both horn and bell buttons it only makes the noise on the horn.

This is just the horn not horn and bell. I think they offered this back as the cheap alternative to the TB system that did horn, bell and motor noises.

Any one else ever have this problem?

Have you tried reversing the wires from the CW-80 to the Williams F7? Don't like to mention the other possibility but that is you have a bad horn unit or the circuit board for the horn unit is bad.

Williams was having some problems with one or two suppliers for their sound units and either changed suppliers or quit selling engines with sound units a year or two before Bachman buy-out happened.

The True Blast 2 system was horn or bell sounds only, NO motor sounds! QSI units offered in some of the more expensive F7's had motor sounds as well, must have the emblem from QSI to have motor sounds from what I know about Williams.

Does the F7 run the same direction every time when the reverse unit or switch is turned off? I had a problem with Williams F7 engines going the opposite direction after throwing the switch to lock it in forward. Two or three hours later after being unpowered the diesel engine would go the opposite direction.
