Today was a happy day….yesterday was an angry/disappointed day.
I worked on marrying the two sets of horns to make one correct set. The internals of what I had plus the “new” trumpets I found in Hershey. Should be easy, right?
Well….not so fast.
First, I found that the hole pattern was about less than an 1/8in larger on my old internals. So, I had to grind that down to fit the new trumpet base. That wasn’t bad. Then, I had to drill out all the holes on the internals so all the bolts would sit properly. Even that wasn’t too bad, but took some time.
Then, put the first horn together, install it, and test it….nothing…just the click of the relay…no beep.
My next thought was…”great, I went from horns that didn’t look quite right, but worked that I could have been content with to horns that look great and are correct….but don’t work!!”
After some experimenting with another battery on the bench top, I could get a very slight, but only momentary vibration. So, I started thinking my battery was low. It was, but not horrible. Put it on a charger.
Went back to tonight to try it out…still nothing. So full disassembly. With a lot of experimenting I found that there is a quite small window on the adjustments where it works and sounds good or doesn’t work at all. Got it working tonight. Then, went through the modifications on the second one tonight. It worked fine when I was done.
So, after a little frustration yesterday, I now have correct working horns.
