I installed a new 1314-200 Sure Power battery separator to replace a very old one I think had gone bad. Two reasons on the old one. First, I've stopped hearing the distinctive clicking of the solenoid clicking open and closed. Second, I'd turned off my truck (senior moment as I have ALWAYS left the truck running with the air compressor in use...in the past) and aired up two trucks with my compressor at the end of the Monache trip. That killed both the aux battery and my main battery. It shouldn't have killed the main battery. It should have disconnected.
I ordered and installed the new one wired exactly as the old one. I got two distinctive clicks when I connected the main battery cable to the separator, and nothing since that. Ground wire was already attached when I connected the main battery. Both batteries read 12.1 with the engine off and 14.5 with the engine running. Drain on the main battery when starting the truck went down to 11.2. Running Optima Red Top batteries. They are 8 years old but voltage shows they are still good.
Do I have a defective unit? Aux wires to stuff in the truck is wired both to the Aux side of the separator and directly to the battery in the case of the compressor and winch. Lights, ham radio, etc. are connected at the separator. It's been that way for years. Original separator has to be over 8 years old as I had it before installing the Optima Red Tops in April, 2015. Good life out of the Red Tops, but part of me wonders if the separator isn't working due to age of the batteries, despite the voltage numbers looking good on both batteries.
I'd love to solve this soon as I don't want to get stranded with dead batteries from just the fridge running if the batteries aren't truly separated when the voltage on the main drops below 12.8V.
I am in contact with the seller of the separator and they are contacting the manufacturer on the issue too.
