Check voltage coming out of the dash assembly and you can do that with hte main four wire plug in on the dash, and by using a volt meter on the pins for each function. You could even hot wire a pump at those dash pins if you would like. To do that you will have to remove the clamp strip on the dash, and the dash from teh actual boat dash. Then you can turn it over to access the functions. As Rlb8s points out, there are drawings and diagrams on the main page for this. We think usually the functions are another issue and not the BP dash, though occasionally it is the dash. On a boat this age you can do a conversation, or you can also run seperate switches for the pumps or features. It sounds to us like a ground problem from the terminal block on the transom, in the sump area. Check all those wire ends in the sump and for continuity through the grounds. BCB
