Recently purchased a 2005 Suzuki c50t. I purchased a Kisan Trailblazer off the internet. When I installed it, I noticed that when the bike was running, the brake light would flash fast then slow down but would not stay steady. After it would slow down, it would start the flash cycle over and over again. When the bike was not running, the modulator would work perfectly. I contacted the Kisan company who told me that the older model "4 1/2 years old" modulator was not compatable with newer bikes. They recommended placing a "electrolytic 100uF capacitor" in the line before the bulb. Has anyone had this problem or know of a solution? I thought I would ask anyone if they have a different solution.
