Jay,

I am building my electrical system for an all-electric ship and I had concerns about wanting to know if any of my battery bus fuses had blown. I didn't want to be merrily flying along on my backup fuel pump or ignition without knowing it and making a concious decision to continue. I have LED indicators for my battery bus loads on a visible fuse panel, but they are at the far right of my cabin so I wanted a testable/resettable master flashing LED right in front of me. I posed the this goal to an electrowhizzie forum and got this design and commentary from a senior member. Hope it helps.

John

Hey there John,

Thanks very much for this- pretty complex looking for a fuse checker! But I understand your requirements and they have merit I think. My fuse checker is very simple and does not give you an alarm when a fuse blows- but this I think you will figure out when something goes wrong- although if it is on a cct that feeds an essential item like an ECU, via diodes, you are right in that you may not know about a single fuse failure. Hmmmm…

Thanks for the info and cct diagrams!

Jay
