New symptom to report: the tail lights and brake lights work with the key on but I get nothing from them when the bike is running.

Okay, after 14,000 faithful miles, I'm going to reward Big Red (my trusty Cyprus 250) with a horn upgrade. I want to give him something that has a little more beefy sound. Here's the catch: I really just want a plug-and-play solution that I can do quickly using the existing wires.

Anyone know of a great horn that is ready to go for Big Red?

I have a 2008 MC-54-250B with a strange problem. Both brake switches failed last week, which is not that strange for these bikes. I've replaced the rear brake switch twice already because they apparently are known to fail. The strange part came after the replacement switch had been installed for the rear brake.

When I got home after my ride to work last night, I discovered that my brake lights were on constantly. I pulled the left brake handle and they turned OFF. The new switch is working BACKWARDS--the brake lights stay on until the brake handle is pulled.

Even though I figured that this is just a dumb switch, I pulled the two wires off and switched each one to the other terminal, but got the same result.

Any idea why I would get this result?

R/R is definitely toast, and it answers another question I had. When the weather got warm enough to ride in February, after I would get home, there would be a bitter smell that I couldn't identify. There also seemed to be a couple of drops of a strange substance on top of the muffler that was the origin of the smell. Turns out that the R/R's resin (or whatever that stuff is on the back) had been heating up enough to melt and drip a few drops on to the muffler.

After changing almost all of my lights to LEDs, I burned up my battery with too much voltage from the charging system. I've changed some lights back (headlights are 50/50 Xenons and the stop/tail lights are Sylvania Silverstars now), to try to hit a happy medium.
My new battery measures about 12.75 - 13 across the terminals at idle.

What should the battery voltage measure at higher RPMs like 1k, 2k, 3k, 4k etc? I don't want to blow another battery.

My battery box doesn't look like yours. There's no fuse box near it. I could only find one fuse in the area. Could this fuse box be somewhere else on the bike?

Here are photos of the battery box (which is off the bike) and the engine compartment where the battery goes. I put a green circle around the only fuse that I could find.
