I set my trailer up with it since the backup assist came with the truck. It is actually pretty neat and works well. But I never use it. My trailers are 16 - 24' so they are pretty easy to backup.
Disconnect the wire in question and run a temporary bypass for that wire (don't run through the tunnel) and see if that changes anything. If it does, you know the problem. If it doesn't, just reconnect it.
I use 2 different mini hoes (they are not Power Trac models) quite a bit. They definitely put a huge amount of stress on things the way I use them when digging through our hard clay and shale. The swinging one can put some sideways stress especially when using it to pull logs sideways out of...
I am currently welding an 1850 adapter to a 1445(?) 4-in-1 bucket (I wanted the width to be as wide or wider than my tires).
Does the bucket bend if you hit a stubborn rock while cutting in reverse?

If they are cheap and aftermarket, they are single coil. I do not know if the two coil ones are made any more. Some Deutz distributers were selling single coil the last time I looked.
An additional pair of hydraulic circuits is an upgrade that I use a lot especially with my V-plow and swinging mini hoe. It is also very nice not to have to keep undoing the auxiliary circuit when using hydraulic attachments. I definitely do not regret doing it.
I have one that came with my tractor. I have never used it but you are welcome to stop by and try it or borrow it for a few weeks since we have the same attachment plate.
