Tether heating up!
Today, when we first hooked up the RC to the OI with tether today, the serial cable heated up to burning. I don't think the OI or the RC is damaged by this, though. The entire circuit was hooked up correctly.

here's what we did:
We connected main circuit breaker to the fuse panel, put coinnected power to the RC to the fuse panel and put a 20 amp fuse in there. We hooked the battery up to the circuit breaker, put the tether from RC tether port to OI tether port, and turned the power on. For a few seconds, everything worked, but after a few seconds, someone felt the tether cable get really hot and we saw the OI lose power. We quickly disconnected the tether.

We tried doing this again with another tether and the same thing happened. Has anyone else had this happen to them? How do we fix this?

PS we are now giving power to the OI through the power adapter and communicating with the radio. But the radio is giving us a radio fault and we fear that it might be related to the tether burning up and (if you gus remember) the OI displaying info one digit at a time the other day.

Please excuse any poor grammar, I'm typing very quickly right now.
