JD 1010 RU - 1962 low serial number 12v system 6v coil
I have replaced the key switch with resistor twice. The coil is 6v. The first new switch was bad and had no voltage in access position.
I have attached the battery (B), ignition (I), and start (S) wires to the second new switch. Nothing is attached to the 'F' terminal or the accessory terminals. Tractor will start and run with key in start position. It dies when key returns to run. Voltage at the coil (+) is 3.5v with key in run position. Voltage at the coil (+) is 9v with key in start position. The battery is a little low but tractor starts easily and runs ok as long as key is held in start.
I have studied all of the related posts and tested recommendations, but have not found the answer to this problem. Any help would be appreciated.
