Logically, you are absolutely correct. I brought up the current draw possibly increasing from poor connection because of an experience I had with a switch on a piece of equipment (DC circuit but not car) blowing a fuse. Stuck with me all these years and still look for stupid unexpected stuff like that when on calls today.

Looking back after the fact, switch appeared to make/break properly, no shorts, external contacts & connection good but after some use, got warm-- but not enough to smell or smoke as customer didn't notice anything other than it was inoperative.

Don't know why fuse would blow instead of just component quitting other than the contacts arcing & heating caused too much draw. By the time I got there on service call, all cool, replace fuse and seemingly OK for another period. Took a while to find the real culprit but changed the switch and all was well.
