Might want to inspect all the contacts, mate and break the connections to buff them shiney, might want to spray contact cleaner in there, allow plenty of time to air dry (or use a hair dryer) and inspect again to make sure they are shiny. Use dielectric grease to protect contacts from corrosion/moisture.
Also check back the wiring, especially where they past thru the metal bracket/clips that prevent the back tire from catching them...you may have cut insulation and when you moved the wiring, temporarily un-grounded the exposed wires. Several layers of electrical tape should do the deed or heat shrink tubing, if you can get it on to the exposed area.
