2004 Cummins ISL 400

[Don Colapietro]

we are working on a 2004 Cummins ISL 400 which died on its maiden voyage. running just fine, then shut off... no spitting or sputtering, just shut off and would not restart. plenty of fuel at the filters. it has a brand new ECM and now shows a code for speed sensor. getting tired of throwing new parts at it. we know just enough to be dangerous. some of the DC voltages at the ECM seem to be low. HELP !  where do we look now?  Don Colapietro 239 940 6199  Thanks

Since you indicated possible low voltage issue I'm assuming you've checked all chassis battery connections , especially ground wires. One suggestion would be to start the generator and get a charge going on the batteries - that should raise the battery voltage enough if you happen to be just on the edge of a low voltage issue due to wiring problem.
