Hi, Greg, nice name, for this scenario you will need your service manual that has all fastener torque specs -fluid capacities and a wiring diagram on the back pages, parts fiche, and owners manual if you can not find the best tool you ever bought for your Harley, despair not, for a mere $15 you can download another one.

Did you overfill any of the fluids you changed?

Check the acc fusing but probably it is a wire loose or off of the acc plug assembly.

It is possible that whoever did the trike conversion did not figure out the sub harness they added correctly, or left something unplugged. Could also be a broken wire inside the insulation. As complicated as a Goldwing electrical system is, you may have to go back to the person/company that converted the bike (if done by a company specializing in conversions) or find a crack Goldwing mechanic that specializes in electric issues.
