MD11SR Fault code 35

[Chris2005]

Hi All,

I am having some problems with a MD11SR with blowing fuse F307 and bringing up fault code 35.

I had a look at the unit about 2 weeks ago with fault code 35 run circuit and found that fuse 307 had blown,

I checked the wiring and found the high pressure switch wire had rubbed through and was touching a pipe,

I repaired the wire and thought that would solve the problem, but today I had to go back to the unit and the same thing had happened again , fault 35 and fuse 307 blown.

I checked the wiring again briefly as it was blowing a gale and pouring down, but I couldn't see any other damaged wires.

Regards

Chris

Have you checked the Fuel solinoid?

[Chris2005]

Hi Moggy,

I havnt checked the fuel solenoid as the engine was running fine,

is it part of the run circuit ?

[moggy66]

Sorry no i was lookng at the wrong diagram,F307 protects the #8 Circiut power ,check Air switch, pilot Solinoid, Thermax Solinoid.

Agree with Moggy66, guess is another chafed wire somewhere. Why do you always seem to get them Chris?

Hi Dave,

I guess I'm just one unlucky MO FO,
But I always get there in the end with a bit of help :)
