EDIT - FETs for high current, low voltage does appear to NOT work, I destroyed numerous PFETs and before they blew, the voltage drop across the H-Bridge FETs was around half of the 14.2VDC supply, so I didn't have enough power going to the winch to do what it was supposed to do. The last set of FETs that blew while I was trying to reel in the cable blew in such a way that the cable started reeling out and couldn't be stopped except for disconnecting the supply to them - Back to electro mechanically relays.
I have an off road vehicle and the stock winch control relay failed, so I made an H bridge using 2 PFETs in parallel and one NFET (IRF4905 & IRF1404Z) and I'm thinking of how to make a remote control for it. I was thinking of using one of those dual direction cord reels, but they are only about 8" long. How hard would it be to make an optical or RF remote with only 2 out puts that won't be bothered by bright direct sun light of interference from something like a CB radio. I haven't done anything with either yet, so any advise would be appreciated.
Thanks, Kinarfi
