It's possible that a couple duds escaped any testing they're doing, but for a team to go 0 for 2 on semi-random pulls (we'll assume there's a degree of randomness with Amazon's fulfillment network that picked and packed your Sparks) would surprise me.
(Full disclosure: REV donated four Sparks and a Digit board to Team Cockamamie's Robot in 3 Days build this year, and Greg and I have known each other for some time. I'd say the same thing about any brand of speed controller, though.) |
If I were going to venture a guess based on the limited information in the initial post, I'd say they have their PWM wire or their power wires plugged in backwards. My only complaint about the spark was that the white molded "B" to signify the black wire on the PWM connection didn't jump out at me when I was looking for it. I had the same complaint on the old victors too.
