Need ignition switch help

[Seanking4211]

I replaced ignition switch with one that doesn’t have an auxiliary position no gauges work and blower not working but Bilge works it’s 80 model cobia 170 with 4cylinder mercruiaer

The bilge is fused straight from the Bat. The blower normally has no connection to ignition power.

Look for a 20 amp inline fuse on the Red/Purple wire
Also measure voltage on the Red/Purple it should be there always

I/Os usually need ign power to feed the CDI unit or coil. That serves as ign accessory on that ign switch, as they do not have a dedicated accessory wire.
