I'm stumped. The left sling on my Quicksilver keeps blowing the transistor the second the ball hits the target. Using the correct coil (with no diode, just the one on the right), the diodes (IN4004) on the switches are not blown, and everything appears to be wired up correctly. It doesn't blow until the switch is hit, but then the coil locks on. What's my next step?
PS: top pic shows diodes cut so I could test them w/multimeter
