$@#$@#$@#$@#$@#When Innovation FIRST Spikes are exposed to a ground, thir internal circuts will freeze to form an open circut. This will usually render the device into an uncontrolable +12 Volt state.
$@#$@#$@#$@#$@#This is a common problem for teams with a grounded frame. So you might want to check that first. Hope this helps.

: Hi everyone, I met with the engineers on our team the other night to run a check-up on our robot. We quickly found that one of our window motors that uses a relay, wasn't working, even though the relay was signaling properly. After checking the connection at the window motor, we examined the relay.
: The terminal that joined the relay with the wire was very loose. And oddly enough, this was the second faulty relay we had this year. Has anyone else had this problem with the innovation FIRST relays?
