guess the radio was not on your radar... if it had or has not worked for years it is understandable that would maybe not be considered.    sure glad you found the reason for your problem.

Yeah Floyd, radio was the last thing on my mind. Very glad to have finally found out what was killing the battery. Thanks

Seen a lot of aftermarket electronic add on equipment direct wired and not ignition switch powered kill, or deplete batteries over the years. 

Worst one I ever worked with automotive related was an early Audiovox remote start system nobody knew was installed onto the vehicle. The receiver portion was buried in the roof and the power wiring was run down the inside of the driver's side "A" pillar and under the dashboard. A little stub wire antenna was affixed to the rear view mirror behind and could not be seen from the interior of the car. 

Owner fought that for quite a spell before dropping it off at my place to finally have it diagnosed and repaired. Took a couple of days as the installation was very good. This would have been highly suspect right out of the gate had the owner known about it but did not, nor had any remotes for it. 

It was removed and problem went away.  
That's All Folks!

Charged up the 4 year old battery to 12.58 volts . Unplugged charger and let battery sit all night . This morning it's 12.31 volts . Guess I need to keep an eye on it and see if it drops anymore ? Was planning on putting it in my D 15 . Any thoughts ? Thanks !

If it REALLY was fully charged and not just a surface charge, it should maintain over 12.5 for quite some time.... You may want to monitor it for a few days... charge one more time and then long term test again...

Thanks Steve , that's a helpful chart . I'll check it again tomorrow and if it's still 12.3 volts I'll put it in the D 15 and see what happens . It usually starts right up .

Put this 4 year old battery in my D 15 this morning . Tractor started easy and voltmeter was on about 13 at idle , 14 at half throttle . Just checked battery and multimeter reads 12.82 , so I'm thinking that's good . Maybe I can get a couple more years out of this battery ? Thanks !
