Ecm replacement...

[Kid Rock]

   UPDATE:

Been tracing down a lot of J1939 wires...

If the 2250 ecm gets its power straight from the battery via an inline fuse, I think I may have found the culprit...

*major symptoms have been, no primer pump, J1939 failure, CAN NOT hook insite up through the 9-pin or the dutch ( won't communicate ) ... motor won't start *

Found out;

[from the battery]-The positive wire, with in line fuse (30 amp), was in bad shape;
- the fuse was blown/corroded
- the fuse holder was corroded
- traced the wire up out the box, it was corroded and broken from the wire that goes up into what I think might be the ecm
- rewired it with all new wire, new fuse, new fuse holder

But on the ground side of this (ecm power?) circuit, I found a weird piece. It looks like an inline fuse or maybe a holder for a resistor? ... well it's corroded too and whatever was supposed to be plugged into is missing. Tomorrow we go to hunt for this piece so we can finish the circuit. And hopefully restore power to the ecm

Does anyone recognize this piece? It would be real nice to know what this is. It just says "AMP" on it ...
