-----Question-----
OK.... There was a mistake, the batteries of my RV were mistakenly replaced
by 12 volt instead of 6 volt.... so the Aux. Coach part (there are two sets of
batteries) of the batteries got 24 instead of 12 volt. I saw the leads becoming
Red Hot and immediately disconnected
the batteries. Now.... After replacing them with the right batteries... i start
the engine, it ran for 2 minutes then died. It looks like the Fuel injector does
not get any power. Theres no fuel going into the injector. Solenoid is closed?
Computer Fried? I checked all the fuses the 5 fuses harness. I think there
must be another fuse..... How do i reset the computer.... Think i need a
diagnostics computer....? I am in Destin FL.... nearest Cummins Service is in
Mobile.... Have to tow RV? Any suggestions? I Already replaced the Liftpump
and all Filters. There is some air in the lines....but the fuel level stays where it
is...no advance. . The Solenoid? Where is it Located?
-----Answer-----
No solenoid on ISB.The ECM controls voltage to everything on the
engine.Check the 23 pin(round)connector pin A for key switch ON
voltage.You can remove the ECM
Answer I got my wiring diagram so you will need to check pins B,C,D,M,& S for 12V POS & pins E,F,H,P,W,& Q for ground.There are 5 fuses somewhere for the ECM,three 7.5 AMP & two 10 AMP.Most of the time there near the batteries but not always but they will all be together.If the "CHECK ENG" & "STOP ENG" lights do not come on when key is turned on then thats the first place to look.
