Can you turn the motor over with a wrench on the crank pulley? If so, it appears something in your wiring is bad. A quick drain down of your new batteries indicates a serious short or leak to ground. You might try:
1. Disconnect all the wires on the hot side of your battery
2. Test each with with an ohm meter to ground, they should all be "open", no reading on the meter, unless there is something turned on with diodes in it, if so, turn the item off or un plug it. The wire to the starter solenoid or directly to the alternator may show some reading because of the alternator
having diodes in it. I don't think it should be a low level resistance reading, however
3. Isolate any wire, either at the battery, or at the fuse/breaker buss that shows a resistance reading
4. Make sure the wire or wires from your alternator are re-connected to the hot side of the battery before starting the engine, do not run the alternator "open".
5. With everything but the alternator wire(s), or the wire to the starter solonoid removed from the hot side, use a heavy jumper cable to connect battery to the starter terminal. If it turns over but won't start,
jump to the glow plugs for about 5 to 10 seconds, before trying to start again.
Disclaimer: I am not an expert on anything, only relating what I would try on my own engine. Use this information at your own risk. If you are not fairly knowable about electrics, I strongly suggest you hire a good reliable licensed electrical tech to help you. Let us know what you find.
Forgot this. If your engine has pre-combustion chambers, & I think it does, I have read that using ether in them can cause heap big damage. I used just a small whiff in a VW diesel once and got away with it, but I only did it once.
