a 2033. Shouldn't you know what that number means before replying?

Not sure why there's any problem installing the electronic horn in that...
Funny I've torn those horns completely apart in the past and never thought to try the simplest fix, clean the tarnish off the battery contacts - doh! I'll be trying that on a few stubborn ones in the roster.

I would add one thing. I would put a light film of motor oil on the contacts to prevent corrosion. This is all the contacts: the rim of the diaphragm, the rim of the horn body, the rim of the cover, and the center electrical contact.
There is a contact in there that is adjusted by the outside screw. The horn is really just a fancy buzzer, the magnet pulls the diaphragm down until the contact opens, then it drops back, the contact closes, the diaphragm is pulled again, etc. The adjustment screw sets how far the diaphragm moves, and thus the pitch of the horn.
Most problems I have encountered are caused by excessive handling and oxidation. The wire that comes out the back of the horn is very fragile. It doesn't take much bending for it to break off at the plastic bushing. Oxidation occurs at the contacts of the relay. The rear hinge area of the moving bottom plate and on the face of the contacts themselves.
After cleaning the oxidation points of the relay, a gentle working left to right of the set screw on the horn's back usually gets the thing going.
To all...
Thanks for your help.
I removed the cover and sanded (cleaned) the contacts for the vibrating arm and the top of the solenoid coil. The video that was posted on this string of discussions, showed that you can test if it works by touching a ground to the top of the vibrating arm and pushing it close to the solenoid coil...it will create a slight noise and pull the vibrating arm down to the solenoid coil. It works in the video but does not work for my horn. This seems to mean that the solenoid coil is bad. Is this possible? If it is bad, then the horn is gone...but I would like to understand how the coil could be bad. It looks intact..but the copper wire surrounding the solenoid is covered with paper...so hard to tell.
Does this make sense? I assume the horn is gone...but would like to understand how the coil can get damaged or not work.
Thanks again

The PW horns were the same as Delta bicycle horns. And there are people who restore PW bicycles.
See this example and the associated video link:
It's been a while since I had a horn apart. As I recall, either the end of the coil wire inside the horn or the joint where it is attached to it's contact can become severely corroded causing the horn to fail.
