Low voltage alarm keeps going off intermittently. It seems like it has always done it when I extend the unload auger until it's extended. The air conditioning blower also has an effect on the voltage gauge.

I had the alternator and batteries checked. They checked good.

Check all grounds, especially the one in the bottom of the electrical compartment in the cab. Access by removing the lower RH panel on the right outside of the cab. These things can be frustrating... sometimes running a ground wire from the cab to the frame helps... Worn pulley(s) on alternator allowing belt to bottom out and slip ? Bad Solenoid ? I'm sure others on here will have additional advice

Make a heavy jumper to jump the two large solenoid terminals (the one in the console door in front of the hydro lever). If it helps, the solenoid is bad.

Apparently, NAPA's tester doesn't check current. I put the alternator back on the combine and checked with an ammeter and was getting very little current at the alternator and the battery. Going to put a new one on tomorrow. The solenoid under the fuse panel was HOT.

TNalfalfa, went thru similar problem with my new N6 a couple years ago. That included a 'hot' solenoid/relay replacement. Wireing looked great, alternator, batteries checked, ground boltand rings at lower right cab cleaned and looked great. Still had the problem. I noticed the wires were 'stiff' for about the first half inch at the ground rings. I cut off about an inch from all ground rings and installed all new rings. Instant fix and no problem since. Dang thing had 'bout drove me nutier than I am already. May or may not be your problem but if you get as desperate as I did it's something else to check or do. Might add those wires and rings showed no indication of rust or corrosion they were just stiff.
Good luck with that electrical problem especially when you've checked everything and it all looks and checks good with the problem still existing.
