Im having problems with the lights on my bike. They are very dim unless the engine is revved up. They dont work at all when the engine is not running when the key is on. Blinkers turn on, but dont blink unless the engine is revved high, so they dont blink when im stopped at a stop light. The loudness of the horn also depends on the rpm of the engine.
I hooked up a voltage meter to the battery and got about 4.5 volts with the engine off. When i turn the key to on, it drops a lot. When i start the engine, it goes back up to around 4-5. When i rev the engine, it goes over 6v.
I had a similar problem and replacing the battery cured it. You can buy a replacement battery for less than $20.00. Ensure you follow the filling and charging instructions for the new battery before it's first use.
Merz, $12.59 for that gel-cell is a good price. I just bought one at my wholesale fire alarm distributor for about the same price. And the Genesis brand battery that you're looking at is a better quality than the one I purchased... Anyway, I cut the wires off the old battery and soldered them onto the new gel-cell then covered the terminals with a double layer of heat shrink tubing. Fits nicely in the original battery box, works great, and no acid mess to deal with.
