Bought a 2008 TE510 used. The original owner had installed MOTRAX DinkyWinkaz turn signals. After my first test ride I noticed the front turn signals were not working, upon closer inspection it was because they were not hooked up. When I hooked them up the rear turn signals died. I took the rear apart and noticed the polarity of the rear signals was reversed. When I corrected that all turn signals stopped working. After a lot of testing here is what I have discovered: All turn signals installed on the bike: Correct polarity on all - no signals work Correct polarity on the front, reversed on rear - front signals work Rear reversed polarity, front unplugged - rear signals work Rear turn signals removed from the bike (hanging off): Correct polarity - all signals work Reversed polarity - no signals work Correct polarity with stem of rear turn signal held against the frame - no signals work (and there are small sparks that jump when contact is made with the frame) It looks like ultimately the problem is a ground in the stem of the signals making contact with the frame on both the front and rear signals. Any clue why this would be and how to fix it?
