Roborio 6V Short

[Team1339]

Hello, I have a RoboRio with a short on 6V.  Disassembly and inspection did not turn up anything obvious for the cause.  Can someone please help with troubleshooting or a hardware RMA?  Thanks much.

Hello Team1339.

A short is almost always caused by a metal shaving getting between pins or inside the case. Did/would you try cleaning it with a can of compressed air to try to knock anything loose?

[Team1339]

Yes, we did try that. Not having schematics, it's somewhat difficult though to focus on target areas for the 6V circuit.

The "relay" pins are the ones that use 6V, so I would suggest blasting the whole thing, and focusing there.

Unless something changed, the relay ports use 5v. PWM center pin is 6 v, so that's where I'd concentrate.
