When I went to pick up my new travel trailer yesterday , the brake controller wouldn't work. Trying to diagnose this in the pouring rain is the pits. This was after closing time at the dealer so the shop guys were gone already. The sales manager drove to an auto parts store to get a fuse to try it. Worked!

I've got an assortment of blade fuses on hand, but I clearly need these too, and possibly others. I need a name for this type of fuse.

Thanks all!

 

Cartridge fuse

 

Thanks. Spares on the way.
