I saw a circuit for a FET full wave bridge and used it, so I figure a FET battery isolator would have the same advantages over a diode isolator, lower voltage drop. What I am seeing on Spiced is that once the FET are turn on, they stay on. I tried to set this up so it had to have alternator voltage and ignition voltage in series to turn on the power PFETs to pass current to the batteries, and if either the ignition or the alternator voltages go to zero, the power FETs turn off, isolating the batteries. Any ideas why the "junction" is not going to zero?
Please don't suggest a relay, anyone!!!! I want to make the FET isolator work.
Thanks, Jeff
