Help with 99 Interstate trike LCD display

[Karen]

It started with a rear left LED tailight on my trike that worked on turn signal & brake, but not running. My subwoofer stopped working, and the usual fix (disconnect one of the speaker ground wires) didn't work. I poked around the taillight connections, and checked stuff under the right side cover, put it back together, and now only the fuel gauge is active, and my radio doesn't work at all, no clock display, etc.. The taillight works on a couple of the leds, but no longer works as turn signals or brakes. The fuses are good, and I checked the current to the radio at the blue connector; it looks OK. Anybody got any suggestions/ideas? Thanks for any input, riding without tunes is painful, thanks,
Karen

You blew a ground somewhere........    These bikes are wired butt backwards of an American bike.    Everything is wired hot, and when ya ground the item it works.......  I assume the conversion company keep the ground wire GREEN, so start chasing the green wire from the taillight forward.... 

Another quick place you might look is under the right side cover, there is a ground to the frame there.   Make sure it is getting a good ground/contact, no corrosion and or rust......   Take it off,clean it up good and put it back on.   Test the stuff no workie now, if it still no workie, then head out from the last taillight that worked..........
