My 1456 has not been keeping batteries charged. As tractor is used mostly spring and fall for silage chopping, I put a battery charger to the batteries occasionally to keep them charged. The AMP light stayed lit when tractor was running. ( Kept switch off after tractor is running so AMP light not on continuously.) I had a guy check the alternator with a multi-tester and he said alternator was not working. Last week I installed a new alternator. Batteries were weak when I tried to start tractor but I charged them a while with charger and tractor then started. AMP light still stayed lit with tractor running with new alternator. Shut tractor off and decided to get new batteries to replace the five year old ones . Put in new batteries and engine started as it should with strong , charged batteries. However, the AMP light was still on. I took voltage regulator off and discovered that it was bad. Replaced it with a new one, reconnected ground on battery, turned on switch and AMP light did not light up as it should with switch on. I started engine and AMP light remained not lit. Each time in the last week when switch is turned on AMP light still will not light up. Yesterday, tractor starter would not turn over at all, it did not even click the solenoid. Batteries were dead. I took some from another tractor and started 1456, put batteries back on the other tractor and used 1456 without batteries and alternator wires unhooked all day chopping corn, leaving it to idle instead of shutting it off.
