Grumble snarf. I was tempted to purchase some marine AC breakers on sale a couple of months ago. Melted ice-cream, now.
Finding -anything- in this dust bowl burg is impossible. No cartridge 120-240 volts fuses of any kind. A breaker? Yeah. Buy a square D duplex box and breaker. Thirty dollars.
But your response halted me from doing a sneering Hannibal Lectur on the Whiffie. I'm angry enough at myself for not buying several feet of de-soldering braid when I was north. But I checked a couple of years ago and Radio Shed demanded six bucks for eight feet of braid. And it was gar-bagh grade.
A 15-amp is a pretty hefty element fuse. I've seen 3-5-7.5- and 10 amp fuses open because of age but a 15 is new to me. I left the Whiffie cooling it's heels at 13.20 volts when I went north several weeks ago. Came back to a 12.49 Lifeline (LED meters, and other assorted bleed loads).
I might try a 25 gauge (solid wire, unloaded), as a fusible link. If it smokes then the game is over. Shouldn't blow with no-load inrush (I hope). Man the vents and fans!
