Yesterday I got out my 1200 for some weed spraying duty.Started up and ran just fine but when I hooked up the sprayer I noticed the amp meter was one full notch over towards the "D" side.I got done spraying and I turned on the lights without the sprayer hooked up and nooticed it was doing the same thing.I've never noticed it doing this before.Does this mean its not charging? Please say it aint so.
