2015 Control System Frying Victors

[icecube45]

Hello!
We wired up the 2015 control system on an old drive base (just 4 cims and pneumatics for shifting)

Unfortunately, we've now fried 3 victors with this system, and we can't figure out why.

Each time, a different Victor is fried, all 884s.

From what we can tell from the driver station logs, there is a massive spike of voltage as the Victor fries, 12 volts to ~ 6.5 (this is probably caused by the frying itself).

The driverstation will also get a message about 1 brownout, then continue as usual.

When the robot is disabled, the robot continues to spin in a circle,

we then shut off the breaker.

Any help would be appreciated as to why these victors are being fried.
