Picked up a M35A3 from GL back in July. Drove truck to the farm and started and drove it every week or 2 and it always fired up with no issues until the one day when I tryed to start it and there was nothing. Tested batteries and 1 was bad. Took both batteries to battery mart in town and they tested both batteries and confirmed that one was bad. Purchased new 6tl and took off for the farm. Installed batteries and turned the master switch on the low air light blinks but does not stay on. Removed master switch and tested with ohm meter and switch seems to be good. Appears ot have 2 24 volt feeds that plug in the line side of the switch. Two lines that plug in the load side of the switch. When messing with the connection the buzzer and light came on intermittently but very briefly. Sometimes when messing with the switch the back of my hand would hit the heater blower switch and it would come on also intermittently. Another observation that I have made is that when I turn the blower motor switch on and it does not fire up the 24 volts I previously had at the switch goes away. When I turn the blower switch off the 24 volts at the switch comes back. I thought it seemd like a ground issue so I cleaned up the ground where i attaches to the frame. It did not seem to make any difference. I tried bypassing the switch and it still makes no difference. Does anybody have any troubleshooting advice? Is there a troubleshooting manual that I can download that would steer me in the correct direction? Thanks in advance for any help.Mark
