First post here, wish it didn't have to be in the troubleshooting section.
Here is the short version of my issue:
Reinstalled Integrated taillights (lights work but not blinkers)
Headlight doesn't turn on
Fuel gauge blinks outwards
Bike cranks but fuel pump doesn't prime
I bought a use 2005 CBR600rr recently upgrading from a cbr250. The bike already had integrated tail lights installed but some of the LEDs were out, so I decided to get a new one, the same exact one. All the wires were exactly the same, I removed the rear fairings and discovered the previous owner connected all the ground wires for the turn signal to this yellow "ground" dongle thing and then the other end is connected to the lights. I didn't think anything of it, my idea was just disconnect the wires and reconnect the new ones, and don't mess with anything else. So I did exactly that, turn the bike on tested the lights everything seems to work fine. The next day I tried to go out for a ride, the bike started up like normal everything was fine. I tried to test the tail lights again, I saw that it was flickering and doing weird things. So I turned the bike off but then I wanted to start the bike up again so I can move it into the garage to work on it. This time the fuel gauge start blinking in a outward pattern and the fuel pump doesn't prime, however the taillight seems to be on, but not the headlights, turn signals doesn't work either. I have been reading this forum for the last 12 hours, trying to find anything that might be wrong, so I found the post about the Magic yellow ground box that seems be a the route of all problems. I saw this box when I had the fairings off and someone definitely messed with it in the past, one of the wires was cut and attached to another wire. anyways I looked through the forums and didn't find any mentions about blinking fuel gauge with my symptoms. I also disconnected the lights and still can't prime. I will check the yellow box tonight.
the post below talks about the magic yellow box. hopefully someone can provide some additional insight. Thanks for the help in advance.
