Motorola Spectra fail 1/90!!!

[HAFD_CADET]

OK, so I have a Spectra VHF low power with A9 control head. It was working fine until it was shorted out, and now it displays Error 8/10, then fail 1/90 when I turn it off, then back on. Well, the 8/10 error is showing because the PA board got completely fried, but I know the radio can still work without that board. So now I'm trying to find out why it displays fail 1/90 and I have taken the ENTIRE radio apart and have found nothing wrong with it. I checked all the connections and made sure the control head / radio were both getting power, and I also can't get my computer to read the radio in programming anymore. The control head displays "programming" when I try to read the codeplug, but it just gives me error codes not allowing me to read the codeplug. I also checked the programming cable and all conections, plus the battery in the RIB and everything was good. So I'm starting to think that there is something wrong with the command board, and that it will have to be replaced.

What do you think???

Thanks, Alex

"shorted out"? What exactly do you mean by that? You can correct the 08/10 error by modifying the codeplug to turn the PA off. The 01/90 means that the head is not communicating with the radio, which could be cause by a million different things.

Shorted out as in both power wires touched while it was plugged in, and there was no fuse on the cord. I'm not worried about the 8/10 error right ow because its not causing any problems. I already know "Fail 1/90" is general hardware faliure, but it can also mean that the command board needs to be replaced. ALL connections are good in the radio. I spent a TON of time taking the entire radio apart and putting it back together.
