The only way to fix these problems is to wire the relay fuse or breaker

Scott, couldn't agree more - your comment made sense so I dug up my ol'
manuals for N235SP (an early 235) and checked out the recommended gear
schematic, which would have been the way I wired mine. And guess what?! All
of the power for the entire gear system (except the green down-and-locked
lights) go thru the gear breaker in my manual (and therefore, on my
airplane - I checked). From what you recommend, it must be assumed that
somewhere along the way Lancair "updated" their construction manuals and
changed that little detail.
Also, as an aside, don't know what relays are now being supplied for the
gear pump but my kit came with two of the same type contactors used for the
main bus on/off relay - in my opinion, a good thing as they are designed to
make/break fairly large inductive loads. Using these contactors, the only
diodes needed is across the coils to protect the gear toggle switch.
