@Skyhawk13205 did–

You all are way ahead of us. We didn't use the the canon connections; we used the eyelets with 2 flat washers with a lock washer in the gel and plastic. In modding like this everything we do is a lab test—

Free shipping to our local home depot. Didn't use the bus connection in the odd chance we have to go back. Added the wire ties as insurance. I think they were about $25 each, hopefully they will hold up well—

Our 2003 M1078A1 does on its own cycle to high rpm (though I haven't yet checked exactly how fast) when starting in colder weather. Though it does so after running a bit and doesn't stay there long. Clicking the high low switch always works while in neutral (1,350 rpm) and goes back when...

Removed the LBCD; removed the remote battery disconnect relays; reused the existing wires to directly connect batteries to the alternator and manual disconnect to X1 at PDP and starter. Used gel connections to replace the connections at the LBCD location, Next step: install the 24v AC...

Yes, not in the index, though on the J1939/1587 bus page in both. Once again I bow to you Ronmar. It shouldn't be added to the TM's, my mistake. Let us remove it—

R13?

The previously posted one misses R13 for the later serial numbers; perhaps other particulars?

Done. Thank you—

Two schematics for FTMVA1 trucks by serial number . Appears to include options like: arctice kit cab heater, van, wrecker, wrecker material handling crane, cargo material handling crane, 200a alternator, arctic kit troop heater, j1939/1587 bus, engine harness. Do not recall the source—

Two reasons: 1— It appears I cannot post in the TM's; 2— What I thought was the same revision appears to already there.

Hmmm. We have found the second set, page 21 and on very useful for our M1078A1 18,500+

We dropped the 12v backfeed, though will have 2-banks of 2-31's separated by a battery combiner which will allow the second bank to start assist, if need. We removed the LBCD and battery relay disconnects as you did, though brought the 24v alternator to the battery side of the manual...

We bought this last fall and have already removed it along with our LBCD as we replaced our dual alternator with a 24v 200a unit. Looking to sell our lightly used disconnect. PM if interested—

A 240v 15a unit; what are you planning for power source?

What heat pump did you use?

R12 or R13? is under the PDP; the other R13 or R12 is under the cab below the fuel/water separator. Both are in the J1939 circuit and connected to the ECU/ECM's for CTIS, engine, and transmission. Most likely thing in my limited experience to burn up under the PDP. If one is gone likely the...

Do you have a relay in mind? We found an adjustable under/over voltage relay made for a rack mount for a protected location: ~$25 with shipping. The IP54 rated ones were all over $140, since we splurged on the alternator =/. Planning to mount next to the Victron under the PDP and use the...

Well for 'only' 8x the cost we dropped in a Leece Neville 24v 200a unit. It required modifying the J180 bracket, though used the existing serpentine. Our intended loads add up to more amperage than yours, though I like the small form pad mount unit you have and the thriftiness. Admirable...

I measured the outside bolts, perhaps the insides are 4-1/2". CAT specs more like a 65a for these engines, the smaller footprint may slide right in?
