Wiring problem gilera sc 125 motorbike (derbi gpr 125)

hi thanks for getting back to me!

i really do appreciate it



the rev counter (which is one whole unit with the digital speedo, the digital petrol gague and 4 lights for netural, high beam, temp and oil) is connected at the back with a 12 or more pin white connector block then from that 11 (a guess) wires are taped togetha to make a loom and fed into the main bike body to connect to another, bigger electrical connector that makes up the rest of the wiring loom. along side this 1st loom is 1 wire (the troublesum one) on its own, and rarther than taped, its in a plastic tube but gose in the same direction into the bike.



the wire is then just bared off at the bike end rarther than having a connector on it or spade connector etc.



I have had the bike stripped down to a frame and bare components and i can assure you that there is NOT ONE connector block missing a wire OR component missing a wire i.e. a connector connected to sumthing yet no wire



i have spoken to the garage where i bought it from and he said to me that thee las who sold him the bike mentioned the wire and said "it just earths to the engine to make the rev counter work"



now going on this advice i have tried earthing the wire to the engine in nemorous places and all that happens is that the red oil light comes on



inside the back of the rev gauge etc as regards your question, its just one big circuit board that looks completly fine...and, like i said, when earthed to the frame the rev counter dose flicker



i am lost... i am inches away from putting my dream bike on ebay or breakingit and selling the parts!! hi thanks for getting back to me!
