Thanks all so far. My attempt was a DIY disaster. Just not a handy kind of guy. However, FWIW, the jumpers I made of some Anticables worked out and are quite an improvement over the stock ones. Tried some plain 10 or 12 ga. solid copper house wire. Rolled off the top some. Meh.
Since fuses were mentioned in reply to my post in the "other forum", (and for discussion fun), I am trying some generic (forgot the brand - order from Mouser) ceramic fuses in the 3.7s. A buck or so each. Not bad. And no, I won't get into their direction

. Had used Hi Fi Tuning fuses in my 1.7s An improvement, but not a value.
