I've had a 2005 CAT 247b for a little over a year. It has 1050hrs and is in good shape overall. It was running fine, then parked for 2 weeks and won't start.
Turn the key and no lights come on, hour meter goes blank, no crank
Tried jumping with cables
Replaced battery with new AGM
Cleaned battery cables and checked for loose connections
Checked for blown fuses, haven't found any.
Replaced ignition and safety switch on bar in cab - no change
Have 12.5v between battery posts
Have 12.5v to starter, main breaker and positive jumper post near relays/main breaker with key off
Have 3-5v to starter, main breaker and positive jumper post with key on
Sometimes the dash lights will come on with the key and it will get 12.5v everywhere until I go to start it. Then the dash will go blank and the voltage will drop back to 3-5v when checked. The starter will only click once, no crank.
Any recommendations? I'm at a loss.
