Over weekend was using 1066 to run round baler. Shut off tractor and pulled throttle back a little harder than normal. No biggy but when I went to start 30 minutes later tractor was dead. Batteries completely drained. Come to find out the previous owner had installed + lead from left battery to starter solenoid backwards and throttle linkage struck and stuck to exposed end of cable thus draining system. Lucky I didn't have a fire! Replaced cable in correct position and replaced batteries(needed it anyway). Starts and runs fine but amp meter shows slight discharge @idle and pegs on charge side at 1500rpm. Put voltmeter on batteries and with ampmeter pegged show 14.7 volts. Did I toast something in the alternator?

Nope,
Either your new batteries just aren't completely charged up yet or the air conditioner is pulling more than the system is charging at idle.
Are the alternator belts good and tight?

For sure,
You're just concentrating on that gauge 'cause you had a little trouble with the charging system. :>)
Both of mine will stay down on the low side after starting until I crack the throttle a little and suck in that regulator.
Aren't they just a fine tractor?! :>)

Like Allan suggests it's likely the new batteries simply need a good charge. Running the engine at speed for a couple hours (or leaving a charger on 'em overnight) should top them off and cause the ammeter to run near center within a few minutes after startup.
However your system voltage of 14.7 is a little high on the high side - especially for hot weather. If the ammeter does NOT taper off and the charging voltage remains 14.4 volts there's a problem with the regulator or regulator sense wiring. You'll need to find and correct the cause or risk frying your new batteries!

Hi Bob,
IH internal regulators are a bit high compared to the otherwise "norm". 14.5 to 14.7 volts.
The Red Shop told me that was because of that big pulley they always use on their alternators.
Dunno,
Allan

With all due respect I think whoever told you that is blowing smoke. Only thing a bigger alternator pulley does is increase the engine RPM's where the alternator starts to charge.
Further batteries care ONLY about voltage - not alt pulley diameter, tractor brand/color, etc.

Incidentally we had a CIH 9280 that ruined a brand new set of batteries in less than 3 weeks. Turned out the VR was bad - it was holding system voltage around 15.8 volts. This quickly boiled the new batteries into junk. (However for working after dark the lights were wonderfully bright!)
Replacing the regulator - also replacing an inoperative voltmeter in the dash panel - solved the problem.
