Looking to add a couple small 200 watt heaters (12 v) to my Wolverine dash to help keep my window defrosted. They plug into the cig lighter. I have a full cab system. I'm waiting to have a complete heater installed thru my water but the company hasn't made one yet for the 16 Wolvie. Need to know if the Wolverine stator will be able to take a combined 400 watts....or should I just tie the heaters direct to my battery?
