So I started using my flake feeder this last week. Just supplementing the cows. Mainly figuring out the feeder. Things weren't working right. I was on the phone every day to the man who makes them. He said the battery in the remote must be weak. Got a new battery. That didn't fix things. When I fed on Wednesday it sounded weak. The system is a battery powered hydraulics. When I got home from the sale I put the battery charger on the battery. The needle jumped way up. I am standing there looking at it scratching my head. It is plugged into the truck. The feed truck is a '97 F350. It has an old 5 prong trailer plug. I had an adapter to the 6 prong on the feeder. Hmmmmm. While looking at it from 20 feet away I notice the flapper cover for a trailer plug up under the back of the truck. A closer look the 5 prong had been disconnected and a 6 prong installed facing down up under the back of the bed. Standing up close the the back of the truck you can't see it. Removed the adapter and vertically plugged in the feeder. Now every thing works great. The wife bought this truck new in '97. I asked her and she said her son must have done this but she had no clue.
