Hi guys, I need help with my KE10 Speedo Tacho, it seems to have stopped working completely and i need it working again obviously. :D What ways should i go about trying to fix it? its probably the cable at one of the ends? snapped maybe? Let me know any ideas. + maybe i might just update it to a KM speedo + cabling instead of trying to go the MPH again? Is that possible? Thank you in advance. Cheers Simon.
