The word from the Motorola shop that we got the repeater from was that a lightning strike is what hosed it. We tried to bypass the toint were the 9.6v comes in and then stops via the ribbon cable bit all it does is get real hot and burns up the jumper. The 5v supply is working at 5v unloaded but when the jumper is put back in it drops to 3.2v. The SSCB tries to boot but the test panel just shows FF and nothing else works. Tried applying 9.6v to the test point but nada.. it musta been a st. elmos fire that nailed it. There is no external indication of a lightning strike as in anything blasted apart or anything else.. It would seem that just the SSCB bit the dust.

Are you just missing 9.6V on various ICs, or has that foil actually shorted to other layers?
