My local small fire department purchased 2 MEP-806B's from Federal Property Surplus. Both were not running and had fluids drained. 1 unit only had 6 hours on it, in hind sight this should have been a sign. The other unit has 6965.2 hrs on it.
1. Filled up all fluids, new filters and batteries.
2. Unit with 6 hours will turn over (crank) but not run (start).
3. 2nd unit engine was locked up, found out later the exhaust cover was missing and it had been rained on . Pulled turbo out gallon of Marvel Mystery oil in exhaust and valve cover. So now have an expensive paper weight and parts machine. May put time into it later.
4. So on low hour unit ended up running a jumper from S1 switch 24volts to Fuel Actuator. After reset and little starting fluid started right up, only problem no voltage.
5. Went throught trouble shooting guides, followed Magnetic Pickup procedure for removal, cleaning, installing and testing. No voltage from MPU of 1 to 1.5 volts as manual suggest.
6. With or without jumper I get Backplane (28 LED 5 red) lite up. Low voltage to CMOS.
I have read through the post and have tried several of the suggested fixes. I am not having any luck, any help or pointers would be greatly appreciated.
