Williams True Blast diesel sound board

I thought some or all older williams engines came with a horn. It was horrible sounding, but it was there.

A picture of your engine showing the boards would be helpful.

At least some of the Williams sound boards have potentiometers built into them.  It may be yours is just turned down.  Adjusting may give you your desired outcome.

If installing a new sound board the red wire go to center rail and the black wire to ground.  No need to touch anything else.  Installation of the new speaker is usually very easy.

Hope this helps!

Here is a photo of the board and speaker.  Nothing in the instructions about a horn.  And nothing happens when pressing either the horn or bell button.  Hmmmm.

Dick,

Check your email.  We need to talk by phone.

LOL.  I just learned a lesson.  You have to believe your eyes; not what the box says.  No indication on the box that the loco has sound; no indication in the instructions; in fact the instruction gave the item number to buy to add True Blast.  I bought the engine to run at shows as I know it will go for hours without a problem.  I tried the sound on the show layout powered by old ZW’s with no result.  So I got the inspiration to add the sound module.

Yep, I can hear it from here.

If you have sound, now, the following suggestion is probably useless.  However, a while back....

We (LHS) encountered several WBB engines that didn't have responsive sound only to find that those gobs of (hot melt?) glue on the speaker cone were inhibiting the speaker from.....speaking!  Some of the gobs could be carefully  trimmed back to release free motion of the cone.  But some gobs were so embedded that only replacement speakers from WBB solved the problem.....which they acknowledged to be a random, unfortunate occurrence.

Later production runs seemed to be OK in this regard.

But, since you've found success otherwise, you can file this in the FWIW bin.
