On my John Deere 6620 combine I see the electrical gauge drop and drop the more the electrical demand increases. I believe the gauge displays voltage rather than amperage. With no load and the engine running at high idle the needle can be straight up and down in the black zone of the gauge - pretty much the center of the gauge. Probably shows around 12 volts.
Then turn on the fan and air conditioner clutch and the needle drops in to the lower center, below the black, to the lower green, near the orange/red zone. I am also running an Ag Leader yield/moisture monitor. I should also mention that this combine is a sidehill which takes electricity also. All of these thing might drag the voltage closer to 10 volts.
By the time it starts to get dark and the lights come on the gauge is in the orange/red zone. I noticed last night the sidehill wasn't leveling. Take something off of the electrical load and it would level.
I noticed that I am starting to push trash at the cutter bar. Can low voltage affect the automatic header height?????? Combine is dial-a-matic. Platform is three wire. The head and combine are hooked up with the Deere adaptor wire. Yield monitor this afternoon wasn't accurate like it had been. Shut it down to clean bean dust and it wouldn't start without charging the battery. That only happened once in a week. When the lights are on they seem to stay bright, but the gauge is way low. Battery year is 2013. Is the alternator going south??? With all of this demand should the alternator keep up??? Is there an alternator that is an upgrade or is the OEM alternator OK? Thanks. Andy

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
