Unplug the little black plug on the harness that goes to the little wires on your GPR then cross the two big terminals on the GPR with a big screwdriver see if you get the same noise

My battery light is not flashing, but pulsing as well as volt meter.
No WTS light.
If I turn the key 3/4 way to start, and go under the hood, I can hear something shortin out. Wires to the glow plugs???
Is the WTS light still out ?

Is the chip possible loose ?...

Is the CEL on also ?...(kind of dim)...

The P/O wire is the ground sig from the PCM. Leave the wire off.
Turn the ign sw to run, then reinstall the wire. It should not operate the GPR.
If it does you have to check for a short to gound. I would remove the PCM connector and test the wire to ground. If wire shows good it could be a ground short in the PCM. Thus the WTS lamp.

You switched the idm relay and it did the same? (noise)
