PMMI Musical Horn manual

[mpierce]

It was not working. Leroy said he was sure it was the computer brain, as he had checked everything else. Since I was not getting any display on the dash, I wanted to check the leads.

I bought the new old stock brain on line, installed it, and Leroy was right, it was the brain. It now works. Now, I need to go to a campground with a lot of people, and go thru the songs one by one to identify them! LOL

The brain in my 90 had a little tag inside the box that said "BB 2-90". The new one has a tag that says "PM 5-94". So, it is a newer box. The old box also had a longer connection for the ribbon cable, with a "plug" in the excess connections. The new one the cable fits just right, without the plug. The new box might be one for the newer "Ultimate" horn? But, it works!

PMMI will reprogram the brain with different songs, for a price of course.
