Have94 chaparral 5.7 unwrapped boat ,turned keyno movement of gauges run switch on,shifter in neutral no click at starter.everything else works bilge, blower, navy lights ???
Could be key switch contacts corroded a little over the winter or just plain wore out.
Try it a few times and if its still not working you may need to check that the switch is working and also for 12 volts with a DVM. If you need advice on how to do that let us know.
