6993Fried It I think
- Oct 6, 2012OK, so despite the ever so clear warning about connecting the grounds on the earphone jack and the chassis ground, I did what any good ham would do to eliminate a ground-loop hum -- grounded the whole thing, including my audio hardware (yep, and the earphone jack) to a common ground.
Well now I've damaged the radio and cannot power it externally or charge the batteries through the radio. I think I may have damaged the voltage regulator.
When I hook up external power, it takes quite a long time to do anything, but eventually a message comes up that says "illegal voltage".
Obviously, something is amiss here.
1. Why is it wired that way? You might imagine someone would tie the grounds together.
2. What would the repair cost?
