This is what I'd do... https://www.ebay.com/itm/11-13-Ducati-Monster-796-ABS-Engine-Control-Unit-ECU-ECM-CDI-Black-Box-Module/114027911663?epid=15021768337&hash=item1a8c97d9ef:g:lG0AAOSwM~dd~-4o There's a bunch listed for short money. You haven't said if your bike has stock exhaust.

Figure what it will cost to get a trailer, take it to the dealer in a month, pay the dealer to diagnose it. Then if you have them repair it it will cost you a thousand, or more if race exhaust, for a new ecu.

Your call.

How much of a plug and play would it be to get that installed and the bike running again? Is it simply replacing the existing box or would I then have to reflash the ECU etc?

You'd probably have to have it flashed to eliminate the immobilizer.

How does the effect of the immobilize demonstrate itself? I know everything points to a fried ECU but every post I read on that has at least lights come on and some  life in the bike. Mine behaves as if there was no battery in the bike in the first place, there's no spark it anything. Is that really the symptom you u would have after a fried ecu?

Seems steep too but a new ecu and flash  etc without having confirmed that is indeed the issue here

You are correct that the lights should come on without an operating ECU, which means you missed something somewhere.  Did you check the main fuse?  The fuse for the lights?  Not just visually, but with a meter.  Did you test the battery itself?

No local shop that has some Ducati experience?

Got to get my head back in the fuse box, I only did occular inspection. No local shop with ducati experience, that's what you get when you decide to move into the outback :(

I'm trying to figure out where I could have done something wrong. The battery is fully charged, both connection cables per pole is properly attached, I haven't unplugged any cables that I can think of and yet it is completely dead.

I'll go through your suggestions one by one today

>>>I connected red (minus)first , did not get a spark or anything. But I did have a incident where the battery was turned the wrong way round so the terminals where swapped for a bit. This had the little servo engine to the top right of the battery run with a low vibration until I figured out the mistake.

You need a voltmeter.

I do have that. Any suggestions on where I can read up on how to test fuses using voltmeter?

You can watch this video...

Or Google How to test a fuse.

Another thought along the Diagnostic lead.... a cooperative dealer or tuning specialist might be willing to receive the ECU by mail, test it by itself or in another bike - the return it to you.

The ECU doesn't power the gauges or control general power supply, it is simply powered from the loom.  If there is no power at all anywhere, the problem must be upstream of those components.  Get a test light or multimeter and see where the power stops.  Is there a fuse at the starter solenoid where the white 4 pin connector clips on?  I thought there was.

Which is not to say that the battery connected the wrong way didn't kill some things.  You'll need to assess that when you get the power back.  But I wouldn't buy an ECU at this point of time.

Found the problem. Indeed fuse but not in the main fuse box but a separate box with three fuses right next to battery. Seems to run great now. Thank you all
