Joe, I've done this - my time, it was my Alinco DR-119 mobile, my only ham radio at the time, reverse polarity, _no fuse_, to a gel cell. I wept.
Anyways, you're probably looking for a smoked diode near the DC input. Can you get ahold of a service manual? Google might assist on that. I'll look this evening to see if I can sort something out.

Hi All: I'm afraid that I reversed the DC Polarity to my FT-847. Needless to say, "the smoked leaked out", therefore, the 847 has ceased to operate.
I understand that the 847 has protection for careless hams like myself.. I was hopping that someone on the board has had this experience (no need to reveal). Or if someone could let me know what may need to be replaced to get my radio back in working order.
Many Thanks,
- Joe Westbrook, K7ZT
