    2014 V7 ECU Dead short

    I mean, sure. I could. But as you said, why tempt fate. The bike is running, the sun is out, the money on the new ECU is already spent. Why take the bike down to remove the ECU and open it up? Id rather be riding!

    2014 V7 ECU Dead short

    Possibly. I'd first have to ID that component and unfortunately the manufacturer's markings are all faded and right in the middle of the damage. I'd have to have an electronics expert reverse engineer what it is, then find a suitable replacement, then replace it on the board. I already have...

    2014 V7 ECU Dead short

    Just in case anyone is curious. I found the culprit upon disassembly of the ECU to inspect the PCBA. Failed component circled. Also, note the screw to the right of that component. Thats a mounting screw that holds the PCBA down to the cast metal enclosure. When that screw is snugged down...

    2014 V7 ECU Dead short

    Correct. I meticulously labeled and photographed the main harness connections, routing, every zip tie I cut, etc. All in an effort to get that harness back in exactly as it came from the factory. It was past midnight when I made those last few connections and being tired got the best of me I...

    Oh man, you guys will never let me live this one down... I had the temp sensor and injector connectors swapped. All good now. Runs like a top!

    2014 V7 ECU Dead short

    Update time! New ECU is in and the harness is installed. Fired it up and it runs! Not well, but it's running. One step at a time I guess. Now I've got a P0115 (engine temp sensor) error code. Some more diagnostics in my future I see.

    2014 V7 ECU Dead short

    Anyone know if after installing the new ECU I'll have to do any sort of flashing to my specific serial number? Or can I just swap it in and do the throttle position calibration courtesy of my GTM flash tool?

    2014 V7 ECU Dead short

    Yep! Did that as part of the tear down and diagnostics. Checked that circuit from the fuse to the ECU for continuity, shorts to power, ground, or other circuits. As far as I can tell the harness is solid.

    2014 V7 ECU Dead short

    My new ECU arrived yesterday, a day ahead of schedule. Woo hoo! The moment I had it unboxed I checked for an electrical connection between pin 9 and ground/pin7/pin23. Nope. Nothing. So 100% confirmed my old ECU is internally shorted to ground. Now the big question: Will my new ECU go...

    2014 V7 ECU Dead short

    Thanks Todd! Let them know that ECU Pin 9 (12VDC input) is directly shorted to the ECU housing AND to ECU Pins 7 and 23 (ECU Ground). Super interested to hear if they've seen this.

    2014 V7 ECU Dead short

    Oooo! I've moved up to "pin" status! Cool! Thanks for the feedback Todd. Agreed, I've found the failure but I've not found the cause. That's what concerns me. Will I plug in my brand new ECU only to smoke it the moment I turn the bike over? You can bet I'll be monitoring the regulator...

    2014 V7 ECU Dead short

    ...and the kiss of death.... Pin 9 (12VDC in to the ECU) is shorted directly to the chassis of the ECU. It's toast. Wish I would of thought to check that before I yanked the entire harness. LOL. Found a brand new ECU on E-Bay for $149! Woo hoo! Should be arriving about the same time I get...

    2014 V7 ECU Dead short

    Ha ha ha ha! What dealer? My local dealer pulled up shop and disappeared last year. I'm on my own. Yeah, I'm like 99.9% certain it's the ECU. Maybe Todd will chime in with some sweet wisdom and convince me otherwise, but I agree, it's not looking good. Here's the last thing I tried. 1)...

    Ah, found it. it's pin 9:

    2014 V7 ECU Dead short

    Sorry for the confusion. The fuse only blows when the ECU plug is connected. I removed the entire harness so that I could rule out any other connector or component as the culprit. With only the ECU, Battery +, and Battery - connected on the main harness, that fuse blows. Wire color is orange...

    2014 V7 ECU Dead short

    OK, made some progress but still no diagnosis. Heres the fuse that keeps blowing. It's the 5 amp fuse that the service manual says powers the ECU. I took the entire main wiring harness out of the bike. Like totally out. I then connected ONLY the ECU connector, battery + and battery -...

    2014 V7 ECU Dead short

    No other way around. Short to ground when the ECU is connected. Short goes away when I pull the ECU connector.

    2014 V7 ECU Dead short

    Why is it so dang hard to get proper wiring info on these bikes???!!! I have a 2013 V7 schematic from Carl Allison that contradicts the 2013 V7 service manual, and neither of which match up with my actual bike with is a 2014. There seems to be zero 2014 specific info out there. This is NUTS!

    Ugh, harness extraction. Lame! LOL. Thanks for the advice (even if it's not what I want to hear. :D)
