Several people have responded to the alert message sent out about the need for a fuse in the Instrument Panel Circuit, so now we need to flush this out a bit. No circuit in the boat should go unfused, for reasons pointed out by Dick Bishop.
This one got left out, when Siltala transferred the Lehman control panel to the boat design. According to Siltala this was caught and corrected by 1984, so boats after that year should be fused in that circuit.
It would be worthwhile checking, by looking at the back of the start switch and tracing the wire leading to the instrument panel. If there is no fuse, add one.
