This ole machine is as ragged as it gets. When I first looked at it,the motor would fire right up,even on cold start but temp gauge immediately pegged with alarm sounding and after about 15 seconds,motor shuts down,cycle the key and engine wouldn't turn over twice and it was running perfectly... Kinda jacked up deal but to make a long story short,another repair company had diagnosed it as a bad engine wiring harness BUT WHEN they showed up with it,our pm guy was here servicing other units,they got mad and after disconnecting half the harness,decided to wash their hands of it and left....I got the pleasure of installing the hacked up and partially removed engine wiring harness THAT DIDNT fix the prob....I did go back this morning and wiggle test the dash wiring harness and found the prob,internal short in the harness at the bend coming off the firewall across TRANS
