it is a 1998 M1078A0. Thanks for the detailed explanation! It greatly helps, where the TM did not. I have yet to look at the polarity box. But now thanks to you and the General, I have a plan. I have a voltmeter and a battery tester. The charger I have is one from PulseTech.

The readings were taken with them installed and hooked up as per the TM. I will remove them, charge again, retest and see if that improves the situation. Thanks!

I am having the same problem. Charged batteries, verified at 12.8 V on back 2 and 12.2 V on front 2. Was running fine until I shut it off and tried cranking it again. Truck has been sitting awhile while I figured out my brakes problem... I get dash lights when I turn on Main Power, but when I...

That is excellent advice, I really appreciate it. I will do the shop supply to the gladhand test before going further, to be sure. Thanks

Thanks Mullaney! I take my excitement in small doses. And definitely not in a 9 ton truck going downhill with brakes and hope fading fast...

Thanks Mullaney and Ron. Good to know! Yes, I recall the first time the air ride lifted the cab, that was an interesting moment for sure, this being my first truck with air brakes, etc. The truck is a first generation A0 with the CAT 3116. I live in an area that has a lot of hills and long...

Progress report... After a lot of debugging, it appears I may have resolved some of the issues with the air brake gauges. I went all over the truck and found a few small air leaks and kinked lines (nothing major though). Then I replaced the two air pressure transmitters under the dash...

Thanks for the info Ron and General. I will see what PacBrake have to offer these days and add to the thread what I find out. Looking forward to Sean's video on how he did his install.

My truck is a 98 A0 with WTEC 3. What exactly would be involved in adding an exhaust, or a PAC brake? Assuming the WTEC 3 is already configured.

Definitely not. Harry

I had no real issues with getting ICBC to insure it, once they saw there are already some M1078's here in BC that have been papered. The insurance agent was very helpful in getting around the red tape. I had to register it as a commercial vehicle (at least while I wait for it to be eligible for...

I will do that, once I sort out my wiring issue. I found the troubleshooting section of the TM which gives the detailed instructions on checking for 24 V sender signals, at the PX4 and PX5 connectors on the back of the air pressure gauges and also how to check the grounding between the sender...

One easy question that the manuals offer conflicting advice on: Which is the Front and which is the Rear air pressure sending units? TM Hi, I am getting conflicting info from a couple of the TM's, on which transmitter is for Front Brake Air and which is for the Rear. See two pages below, which...

Thanks, I better go over the wiring in detail with my voltmeter. I bet I have broken a wire somewhere. Thanks again for your help and especially the wiring schematic.

Yes, she is a real nice rig. I named her after my grandma, Gertie who was also an impressive lady originally of German origins and someone also not be be taken lightly. Yes, I had no problem getting it imported, inspected, licensed and insured. In a year I can request Collector plates, which...
