I'm having problems with the tachometer and speedometer on my 21 ft maxium not working. I have the wiring diagram for the boat and it shows the circuit comes off of pin # 1 on the ignition switch and then back to the force Outboard motor terminal block. This is not a fused circuit, so anyone ever have simular problems? It's either wiring or problem with the ignition switch I would assume? I think the force is a magneto type ignition; but not sure? Motor is a 1990 120 HP.
