L4330 not turning on

[kallnojoy]

No reason to replace your battery until you clean the terminals thoroughly and clean up/tighten the ground connection to the frame. If the problem persists after that the battery is very likely bad but still, as Diesel85 said, have your parts store load test the battery. If the battery tests bad then of course replace it.

This. Remove, inspect, CLEAN anyway and reattach the ground cables - especially wherever it grounds to the frame.

Had the same problem recently on my L3800. Didn't bother removing/cleaning the ground because it looked just fine... a couple hours of frustrating debugging later I finally cleaned it and *poof*, back in business.

Where do you live that you need glow plugs in June? …though some diesels are just really cold blooded.
12.7 volts (or 2.1 volts per battery cell) is normal for a resting battery. But voltage, doesn’t tell you how many amps of charge it can deliver. Voltage might be good, but not enough electrons available to flow (amps) for any length of time. Only a battery load tester ($20) can test this. Battery can be tested with battery installed in tractor.
As noted, clean terminals first.

@CobyRupert I don't need glow plugs now. I was just referring to the various lights that were turning on.

Regarding the removal of the battery, this is what someone else on OrangeTractorTalks said about the same issue:

My battery died in the L4330. I know some say it is problem to replace. That is not correct. Problem is a major understatement. My tractor has a cab and air. The air conditioner line lays on top of the battery and the check glass is against the battery. I took out the grill and removed the battery hold downs. I see no possible way to remove that battery. I can't lift it up over an inch as the AC line is there and the hard metal elbow connector to the check glass cylinder is over the batter so of course can't be bent. It cannot be slid sideways as there is a metal brace of some kind on the side requiring that the batter come upwards two or three inches.

Problem solved: Thanks guys for the advice. I was able to get the battery out of the L4330 by removing the grill wing nuts. Then unpluging the headlights,,,, it is locking connector that I finally got loose and iifting the grill upwards and out. I then removed the mounting bolts to the transmission cooler. At least that is what I think it is. I was able to move it from a vertical to a horizontal position as the hoses were rubber. After laying it down I was able to move all the wiring harness that is directly above the batter and the AC line to the rear as much as possible. This allowed enough (barely) room to slide the battery foward enough to put it out. It was not possible because of the hard lines nor would have helped to move the AC check glass unit.

I took the battery out and had it tested at the auto parts store. The battery passed the load tests, so I guess that isn't the issue. Now to start running down other issues.

Are there easy ways to test the starter and solenoid?

Come to think about it, the problem doesn't even get to the starter. When I turn the key after not touching it for a few hours, I see dashboard lights for a couple seconds. And then they go away for good and nothing happens when I turn the key.

Problem solved: The contact point between the battery cable and chassis was corroded and prevented a solid ground. I replaced the old cable and then ground down the contact area on the chassis with a rotary rasp. No problems with the battery; it was checked at Auto Zone.
