Hmm... 14.2 volts is more than a standard lead acid battery can deliver standing by itself. That's the number I would expect to see on the voltmenter if a charger was attached. You aren't testing the battery, you are testing the charger. Either that, or the voltmeter itself is shot.

To test the battery right, unhook it from the charger, let it set for a day, and then measure the voltage across the terminals. That will tell you whether the battery need replacing.

To find an electrical problem I go: battery, battery cables, safety switches, starter motor, fuses. That takes care of most problems.

You're right I did test the voltage while on the charger. The tractor has set for a couple days now so my next move will be to check the voltage. In hindsight I should have checked the voltage before hooking up to the charger. The battery is fairly new and shouldn't be the issue but I will take your advice and start there and work my way down the list. Thanks.
