Hi dear community, have the problem that I have retrofitted this tachometer and connected as follows… Rot tachometer -> red cable at the ignition lock tachometer brown -> black cable at the ignition lock tachometer black -> mass, at the frame tachometer white -> sensor, clamped between CDI and ignition rinse to read signalSwitching diagram of my scooter Despite this installation, which is hopefully correct, the 10A fuse flies out of me, then have a 15A times I also drove with the 15A fuse, after the visit I wanted to drive off, did nihcts on the scooter. Everything remained dead, so the fuse must have flown out as the scooter AUS true! Do you probably notice a tip or a mistake of my installation that I am looking over? AND ? Could I also clamp mass directly to the green cable from the ignition lock ? (see circuit diagram) Thank you already Greeting Ranra
