Hi,
I'm trying to figure out why a 1998 Deere 590D excavator keeps burning up starters. The original starter died slowly after an audible click was heard when the ignition switch was turned and a tap of a hammer got it to turn over a few times. Eventually it died. An aftermarket starter lasted for 10-20 starts until one day we heard a screeching/squealing sound after about 5 minutes of running the engine and shut it down. Upon trying to restart the engine a couple of minutes later we heard a clicking sound of the solenoid but it didn't crank over. At that point we thought that maybe the ignition switch stuck in the start position and the starter was turning the whole time. We also smelled a burned electronics smell around the starter area. So a third starter was installed. The switch was turned to start and deliberately back to run, the engine started and it ran for a few minutes. Then smoke was seen coming from one of the ports of the starter and it died. After that third starter was removed the armature doesn't turn at all.
Any suggestions of where to start or how to diagnose this?
Thanks.
