Hello.
I just bought a 1986 K100rs. It ran perfect for 2 weeks, but one day i just stoppet. And it would not start again. I bought a second hand ignition module, air flow meter and EFI computer. Mounted all of them, but the bike would not start. Plugs are wet, but i only have sparks on nr 1 and 4 spark plug. So i checked the coils. The primary coil, and it was 2,5 ohm on both coils. The high voltage output was 10,2 k ohms on both. Then i checked the spark plug wires. Nr 3 was a little bit "fucked up", but i fixed it so now every cable is ca 5 k ohms. When i measure the other conections on the coils i get 12V on all of them (not the brown), when the ignition is on. Blue/red: 12V, Black/red: 12V, and yellow/green: 12V. Is this normal? I also measure the same from the ignition module. Pin 9, 10 and 14, all shows 12V. I am running out of ideas. Glad if someone could give me some tips. (Inge K. can you call me, or send me a message? 48082445)
