Honda GX630 ignition switch failure

Yesterday was one of those days where NOTHING went right and everything broke. Surface cleaner handle wouldn't release pressure from the gun so I had to order a new gun. Water issues. Not enough hose issue. ((Yearly customer we do but forgot I needed an extra 100ft for the job, but all our extra hoses were on the trailer that was stolen)). ANYWAYS, back to the GX630, it died around 5:30pm. Nothing. Nada. Switch was DRT. Wouldn't show a engine hour (has a built in hour meter) and switch did nothing. Battery was full. No loose wires. Took it most of the way off, but found out it was under warranty so I stopped from going further to not void the warranty. Took it to the shop and it turned out to be a blown 30amp fuse inline under the switch in the housing. WHY they hid it there, ill never know, but basically took the module off the engine, undid the plate, disconnected the choke cable, and undid the housing with one bolt on the bottom of the casing that holds the 2 plastic pieces together. THIS IS NOT COVERED UNDER WARRANTY so I thought I would pass this along if any of you have this issue to check that fuse.

Yeah, I never understood why manufacturers want to hide a fuse. I've replaced many in the Honda twins. The worst is a Generac generator. The engine doesn't have a charging system built in to it, you have to use a cell phone type plug in charger to keep the battery up. The incoming voltage is fused, and the fuse is inside the control panel which, even with the numerous times I've done it, takes me 1/2 hour to get to it and put it back together. The first time I have to replace a fuse for a customer, I splice the wires and lengthen them so I can get the fuse outside the control panel for future ease of replacement. Another one is the Wagner paint sprayers. The fuse is under the motor cover, which takes a bit of work to get off.

Russ, I already told myself if it happened again I would lengthen it to be able to change the fuse out in 10seconds

I remembered this thread yesterday when rewiring the burner to the new motor, touched the wrong with across a connection and blew the fuse... knew exactly where to look, managed to squeeze some space and had it changed out in about 5 minutes... skinny fingers, needle nose pliers and a sprinkle of patience help!
