Saturday was a tale of one man, one Triumph Scrambler, one multi-tester, and one hidden in-line 7.5a blade fuse. Luckily, after hours of where curiosity turned to frustration and then anguish, the moral of our story is that blade fuses are cheap.
Quick-connect dongles for battery charging systems are fused, I knew but didn't think of that. Sometimes those fuses get tucked behind things and you don't realize they are there. Should that coincide with you deciding your battery must be charged... always check the battery first.
Luckily, big boxes of assorted fuses are cheap and easy to have on hand. They do not give you lost time back, however.
