I don't know if my issue is something that might be effecting your bike, but. It took me over a month of changing turnsignals out to find the prior owner had hooked mine up incorrectly. My front signal were wired backwards with the main positive to a ground. I ended up finding a melted connector plug and replaced it prior to Thunder this year, then had to pull the instrument panel apart to clean, oh due to it wouldn't stop poping the 10 amp turn fuse.. All of this started because they wired the signals incorrectly the first time. My guess is that you need to just put the diode on the rear signals since that deals with the flasher. But make sure your wires are correct, and the diode/ resister is connected correctly, they are designed to be connected one direction for the path of elec to flow. My signals has the fast flash because they were hooked up incorrectly.
