Fazerrider,
Have to agree with you on the diagram issue. I to have spent years reading electrical diagrams in the telecommunications and IT industry and have to reset my brain when reading motorcycle wiring diagrams.
One of the best places to start is disconnect all the connectors in the box under the tank spray them with WD40 and reconnect them. This is the first thing I do when I get a fazer with electricl issues, it has solved 7 out of 10 of the problems .I have seen cases of broken earths causing strange problems and it is a likely case.
Since you are familiar with electrics remove the Orange and Grey wires from the coils and with the iginition on (and kill switch on) and spark plug earthed against the engine tap the wires off an earth and the plug/plugs should spark. Thay rules out the coils. The only thing common after that is the CDI.
It may be a CDI issues as His Dudeness suggested as it is common to all, but why a bump should cause it is strange as it is mounted on plastic and rubber. I have never heard of one fail, but there is always a first time.
As far as I remember the 02-03 one is a different part number to the 98-99 one, but there are available on ebay.
