Howdy,
Just wanted to throw out an idea in case anyone else felt the need. My #7 fuse was burnt to a crisp when I received my DMC. I replaced the entire fuel panel but wasn't very happy with the idea of a marginal circuit capacity on #7 possibly damaging the new fuse board. I have mitigated the risk elsewhere by converting to LEDs and low current fans etc. I also liked the idea of an easy means to interrupt the fuel circuit, either for troubleshooting or immobilization purposes. Longer term I would like to replace the entire fuse panel with a CB panel but space is a constraint. Would probably have to create a remote harness and move the CB panel to the rear bulkhead for an aircraft style aesthetic.
Anyway at the risk of irritating the purists LOL here's what I did. Klixon pull-to-interrupt 20 amp breaker from Aircraft Spruce. Tefzel MS22759/16-16 wiring (would have used brown but that's not available ). Aircraft grade crimp terminals. Made a small L-bracket from some stainless stock on the bench-top brake, and used a 90-degree pneumatic drill to make mounting holes as shown. Riveted the bracket in place, and used silicone boots to insulate the terminals. It will clear the lock modules once I replace them.
In case anyone wants to replicate here's the BOM
Klixon 20 amp circuit breaker $20.80
16g Tefzel wire, about 4 feet $2.68
#8 crimp terminals 2 ea $0.60
Window butt splice 14-16g 2ea $1.50
Silicone boots, 1S 2ea $2.30
Sheet metal L bracket- whatever you have lying around
2 x 1/8" rivets
