I just realized that I should share some usage shots of MSD-ICE kit for this thread. Nothing in this post should be new for anyone that already read the "what have you done to your HMMWV today..." thread.
The setup:
In the above photo, you see the second revision ICE Box (green in color instead of black...it automatically detects if it's being powered through the STE/ICE connector or NATO plug). It's connected via W1 cable to the STE/ICE connector of the HMMWV, which is providing power and obviously the main diagnostics. On the back side is the serial cable, which also has a branched cable off of it to provide power to an MSD Miltope laptop from the vehicle. The red cable seen is the test probes, which I had connected to the alternator at the time to do a test to verify there was no voltage drop in the cabling. Unused in this picture are two ports to support simultaneous use of various transducers and a contactless ammeter, as well, the nato power connector is unused. There's also a port on the other side that resembles a parallel port. I don't recall off the top of my head what it does.
Standing Voltage tests:
These are all occuring simultaneously, live. Nothing out of the ordinary here except the starter solenoid voltage. This was with the vehicle switched off, so this may be my pulse charger in the PDU, a failure in the solenoid circuit, or simply the ICE Box may be providing an invalid measurement. I'll be exploring this more later!
RPM Tests:
The idle speed of a 6.5L engine is supposed to be at 700 RPM, -+ 25 RPM. It's a bit high here. I originally tried to tune it down to 700 RPM, but that would allow the engine to stall if I was at high RPM and let go of the throttle.
Around 720 RPM was the sweet spot. Still well within spec, plus the engine RPM never dropped below 359 if I accelerated and then released the throttle. Still to be tested is how the engine behaves once under load. I suspect that I may have to do some work on the injection pump.
Maybe I'll make a video of hooking the system up and using one of the electronic technical manuals to diagnose a failure, should there be some demand for it.
