1988 Prostar 190 Accessory Panel Help

Just wondering if anyone has a 1988 Prostar 190. If so, on the accessory panel on the right with six switches and 5 breakers, is the accessory switch supposed to control anything? My auto pump switch works, but my manual pump switch doesn't. How is the three way switch supposed to operate? Does anyone have a diagram of all of this or any know how as to the wiring? Thanks, Ty.

My access switch doesn't seem to control anything either. I don't know have a diagram for the wiring however try the MasterCraft discussion boards

They is usually someone there who can answer any MasterCraft question

Get underneath the dash and you will see labeled wires with butt crimp connectors on them for each unused switch. I wired my Access. to a cig lighter.

FYI, I don't have any 3-way switches on my 89 ProStar.

I have my access switch wired to the stereo. I don't have a 3 way switch on my '88 190, there is one switch for auto bilge, and one for manual bilge.

Thanks for the input guys. I'll take a look at it. Ty.
