I have the box - relays and all, but no CB60 or wires in the box, Does anyone know if the A1R have the same circuit/wiring? Wondering if they ECU power is in the harness and not a direct circuit breaker connected line ... OR if this is part of the overhaul they just didn't get to yet. Just...

Searching the TM's, I found this for CB60, which confirmed my suspicion it's not in the boxes - but not much else (could only find the operator and technical manual TM's). From the picture, still not sure exactly where to look for it (or where to install it should I need to...). Suspect it's...

Suspect you are both correct and the name may change across versions (?) ... and I have the typo in there as well. Here's a snip from the schematics that I'm looking at - middle left, the LSCD. I'll run through the Niehoff diagnostic steps (found them after leaving yesterday), and see if it's...

Another update from today - the MMDC is installed, but did not notice anything "lighting up", so I started tracing power from the batteries. Didn't take me long to find an issue - the voltage regulator (called LSDC in the specs) - the 24V and 12V lines from the battery to the LSDC are good to...

Yep, what I was expecting. Think I'm going to try to fit it behind the dash, but will have to do some test fitting and see if running air lines up will work. Will also read up on the air system TM's, as I know there are plenty of leaks and a few brake lines to replace. Good news is - believe...

Received today - manufactured 1/24, so brand new. Now a really dumb question - how do I install it? I can see the 2 plugs that go into it - no issue plugging them in, but I'm not seeing any airlines to connect (which I believe are connected?). Looking through the TM's, and not finding a...

Just to confirm - ordered from Ross, and they had it in stock. Shipping to me now. 1 thing down, a zillion to go...

Thanks for the confirmation! - now to see if I can order one. Will try Ross first, and maybe Medallion directly if need be... Thx!

Think I found it - new MMDC for sale here: https://store.rossairworks.com/default.aspx?page=item+detail&itemcode=7020-20044-01&catlist=12&parent=5 Even labeled “FMTV” … and not cheap. Can anyone confirm? (Annunciator is available there as well…) Thx!

Is there a part number from any you have? Otherwise, I can dig into the TM's to find it - just curious if you have it handy. (And yes, learning more on the J1939 and J1587/J1708 bus functionality. Termination is there for the J1939, but still no messages, so something is still not quite...

Update - progress and a setback ... CAN bus is terminated properly, and got some data from the j1587 (I think - reader did not complain it couldn't connect, just said 'no events') - so believe things are talking on the slow bus. No connection yet on the j1939, will have to chase the wires down...

Can kind of - I know there's a method to the schematics - have to lookup a quick tutorial. More interested in any lines that had to be added/customized (as you referred to in the other thread). The J1939 is terminated properly, but have to check the j1587, as seems quite key to the...

Hey- I have a A0 with a C7 in it that is not running, and trying to figure out all the wiriing (ugh!). I have a post in the FMTV thread - no sure if you'll see this anytime soon, but would most appreciate some guidance! C7 engine (new swap) original tranmission (3070) have 3 different TCUs -...

Writing up an update on some research - just incase anyone is reading along - or has ideas. Dug through the pile of parts and found the old 2 transmission controllers (pic attached), as well as the selector (WTEC III by the look of it). (Please let me know if I'm not attaching pics for a...

Cool - thanks for the info. I'll have to see if I can check the serial numbers for compatibility ... somewhere(?). Obviously, the C7 has a ECU, so perhaps that was the reason for the overhaul replacements (still not clear why all things were replaced, but I digress ...)??? And not sure on the...
