I'm not saying that low voltage is the reason for clutch failure just saying what he told me. But how do you charge your yellow top? If your pioneer changes it as it gets low and also charges your factory battery which battery gets charged up first? Both at same time? I really don't know because I only have the one battery with no winch etc. I'm all stock. I have roof and windshield. Just guessing on a cold winter day in the snow working a plow and charging 2 batteries I don't think the stock charging system can keep up with 2 batteries.

Many of us are using battery isolators. If my primary battery drops below 12.7 V, the solenoid will break the connection between the two batteries. Therefore the stock battery will not drop below 12.6. I have all the accessories including the winch hooked up to the secondary battery.
When I put a heavy load on my secondary battery like winching, The secondary battery may drop below 12 V fairly quickly but the stock battery will Drop to 12.6 until the circuit is broken and it will climb back up.
After the primary battery voltage is over 13.3, it will reconnect the two batteries so that the secondary battery can continue charging.
These battery isolators a pretty slick and they're pretty cheap considering the amount of protection they give you.
