Fixed Champion Trike kit tail light
Today I tore into the teardrop taillight that was not working on my champion trike kit.
1. remove the three screws that are inside the fender (need a small 90 degree Philips screwdriver.) Unplug the two connectors and check the connectors for any lose or cut wires. I found one, but it did not complete fix the problem.
2. Remove the screws holding the chrome frame to the light.
2. black back is glued onto the lens. I used a very thin micro flat head screwdriver to work my way around the edge and was able to slowly pry the lens off of the back. It is completely sealed with a silicone glue that breaks free with some patience. Remove all glue from black back and lens.
3. After opening it up I found one of the two screws holding the circuit board to the lens had come out and was bouncing around the inside. I removed the other screw from the LED side to expose the back of the circuit board. I found two wires broke and one resistor broke. I replaced the resistor (they are 68 Ohm) with a 62 Ohm from RadioShack (did not have a 68 Ohm), soldered the new resistor on, and soldered the broken wires. I also found a loose wire at the connector and fixed that too (mentioned above).
4. I mounted the circuit board back to the lens and went back to the bike to test before putting it back to together. lights, brake, and turn signal all worked!
5. I used a craft glue gun with silicone glue and re-glued the back to the lens.
6. Mounted the chrome edge using the micro Philips.
7. Reconnected the two connectors to the trike and used the 90 degree Philips to mount back on he trike
Works like new! Cost me ~$2.50 to purchase a package of resistors. Saved about $180 (light is $155 + ~$25 shipping to order a new one from Champion.)
Tools needed for this job...Small soldering iron, solder, flux, micro screwdrivers (Phillips for the small screws and standard to pry the lens off the back), small Phillips (to remove frame screws), 90 degree Philips (to get between the back tire and fender to remove tail light from trike), wire cutter, wire stripper.
