Gear display missing gears

Hello

Firstly my partner has just brought a Giantco Hunter Sport 125 and me being a dab hand with cars and electronics I have the duty of repairing its faults. With parts seeming rarer than a day without road users swearing at each other I have some wrench time ahead.

Now the one fault that niggling at me currently is to do with the gear display. A simple one block led analogue display which displays the gear your in. Now there is another green light that shows when your in neutral but the led display shows when your in gears 3,4 & 5 but doesn't show when your in 1 or 2. Not an MOT failure I know.

I know how these LED displays work as I have wired them and even programed there driver chips before and I came up with 3 ways in which I could make the very system work. However my 1st guess was wrong as I thought some of the chopped wires behind the fairing whore the signal wires. Its seems every wire seen to be going into the "dash" unit hasn't been cut.

Before I rip the whole bike to bits and go over every wire with testers do you guys know what this may be or how the system actually works?

I have brought the Haynes manual which seems to suggest most Chinese 125cc bikes having the same rolling chassis and engine? but the book is still in the mail.

Cheers in advance.

Does this gives you some idea:

Hello

Yes thank you. It works as I thought. I shall do a second look over the wires and if nothing ill see what its like inside.

Thanks for the link on parts but im unable to read the language.

Google Chrome had "auto" translation.

Well I got the gear position switch out and ran the tester over them and its fine. Traced the wire lome back a bit and found by one of the 6way connectors one of the cables had snapped off and two more had corroded to point of powder. Ill just cut and install a new 6 way an inch further up the lome as there is enough slack.
