KW are great boats but their wiring is kinda sketchy, check your buss bar under the console and verify both positive and negative leads are still on, also check your leads at your batteries.
Could be a faulty circit breaker, are you sure it even has one going to the helm accessories? It could be a fuse somewhere.
Did this just happen by itself? Have seen people change batteries and forget to hook one up when the new battery was installed.
Is your helm fed by a Bussman breaker like this one?
Probably located near the battery. If the little "flag" has dropped down, the breaker is tripped, simply push up on the flag to reset. We have also had problems with these breakers not re-setting, even though the flag has been pushed back up.
