Video of problem: [url]https://www.youtube.com/watch?v=oG6Yp7SGR14[/url]

I recharged the battery for 12 hours at 2 amps but it did nothing to fix the problem. No change.

Two things: Load test the battery. To do this put a voltmeter set to dc volts on battery terminals and while cranking make sure the volts do not drop below 9 volts. If the voltage falls to 9 or below, clean the battery connections or replace the battery as needed.

If the battery is good, remove the metal cover and then the four screws and spring washers holding the control panel down. Lift up the control panel and you will see a black relay with 4 wires on it.

Leave the smaller blue and black wires (0 & 56) attached. Turn off the gas or pull the plug wires.

Pull the other two wires off and connect them together for a couple of seconds (with some metallic object, paper clip, jumper, whatever). The engine should crank. If it does not crank, then it is the battery or starter. If it does crank, then it is the relay.

When the controller wants to run the starter, it applies 12 volts to wire 56 which will pull that relay in which will energize the starter's solenoid. 0 & 56 is the relay's coil, and the other two wires is the wire to the solenoid.
State your problem, not your diagnosis.

Make sure you have less than 1 ohm to the negative battery terminal from the engine and the ground post behind the controller.

It was the battery

I was quite amazed. I was going to do MacL's procedure but I first wanted to try replacing the battery with one of several in the garage I have been reconditioning and I used one of those to replace the generator battery.

VROOM it started right up.

I took the failing battery back to the garage and slapped on the load tester. It read fine on pure voltage but when I applied a load it dropped to 0, it literally pegged 0 on the load tester. Never seen something like that.

That was a new battery 6 months ago. So the generator has been through 24 cranks for weekly tests plus 3 power outages. I can't imagine one battery being able to do that without the trickle charger working.

I see them "peg" 0 (instantly slap 0 when you press the button) more often than to creep below 9 volts in the ten seconds. Glad it was that simple. Hopefully you can return the battery and have most of the cost of it refunded through a pro-rated warranty on the battery.

Without a charger, the battery would be dead in a week, even with no crank attempts just from running the control panel. Hopefully you have proper charger in there, however, one with a 2.5amp output. I don't really like the typical charger that is acquired from Wal-Mart, but only because they are nasty installations and sometime hard to know if they are working since their output usually stops when they are disconnected from the battery.

The control panel should stay up when the battery is disconnected, if the charger is working. The output ideally is 13.53 volts, nothing less and not more than 13.80. If you disconnect the battery you should be able to read the charger's output on the battery cables. You may have an older style charger in there that most of them have bitten the dust. Those often fail by putting out too much voltage, such as 16 to 19 volts.
