    M-1078 Door Handles/ Interesting Topic?

    I used the Toyota 95 - 04 Forerunners as was stated by RonMar and found them to be a very good choice. If you use the stock door locks the you will have to turn the handle upside down. I went back and watched the video that was presented before and saw that a Trimar latch was used and it appear...

    M1078A1 Caterpillar pin outs on computer schematic

    So I tested my wiring and found I had the correct power and grounds. Then I checked to see if I had continuity between my ECM connection and Data Port. I called Caterpillar and found out that they could Bench Test my existing ECM to see if it has life. Now my question is since these ECM's have...

    M1078A1 Caterpillar pin outs on computer schematic

    I really did a search because I had seen where someone had written in about a no start on their engine. I could not find it and I knew at the time I should save it but... So I am asking if I could borrow a cup of schematic for the engine computer so as to check for power and grounds. Please and...

    M1078A0 Parking Brake Diagnostics

    So I got my new Brake Check Valve and lo and behold it worked. Thank you. Now as far as the capped line versus the vented cover, not that I doubted you but I verified it, you are right and the trucks that have a slow release on the parking/ emergency brakes are found not to have vented caps...

    M1078A0 Parking Brake Diagnostics

    The problem is found but not verified meaning I found the check valve that connects the Emergency Glad Hand to the Wet Tank in fact was bad. Enclosed is a picture. I will explain the picture because it is not what I expected. I expected to find a spring loaded ball bearing type check valve and...

    M1078A0 Parking Brake Diagnostics

    Yo Dude!!! You scored 100 percent on that one! Diagnosed just like you said. So then that Check Valve is bad? or can it be repaired? or is it just best to get a new one? By the way, that is a fantastic safety feature all right there. Not too easy to get to but not impossible. Just for grins...

    M1078A0 Parking Brake Diagnostics

    Thank you for clarification. I understood that and my mind went off immediately to prove it and when using these as High Water Trucks for rescue that may come in very handy.

    Niehoff N3030 Regulator/ M1078/ doesn't have flashing light capacity

    I finished my rewire and am quite pleased. Thank y'all for the assistance. My problem with the starter lockout relay is only going to be remedied if I find a way to delay my alternator from starting so soon. I have seen mention on the internet that there are one wire alternators that have a...

    M1078A0 Parking Brake Diagnostics

    Well, by the title it sounds easy!!! By the way, a salute to RonMar on an incredible explanation of the air system in these trucks. Thank you Sir. I have a set of parking brakes that release anytime there is air in the system. Now I can release them if I remove the line on the Inversion Valve...

    Niehoff N3030 Regulator/ M1078/ doesn't have flashing light capacity

    The conversion is going great! And I plan on giving more information when I am done. I encountered another problem and looking for a remedy, I figured and proved that as soon as I bump the starter button, the starter lockout relay does its job. My 24 VDC alternator is a one wire alternator and...

    M1078A0/ Allison MD3070/ Drain Plug Threads

    So in further pursuing this issue I went to Allison and the parts department at Florida Detroit Diesel said that Allison has no resolve for this. I then got ahold of Weller Truck Parts, Grand Rapids, Michigan, pointed me in the direction of their remedy and that is Drain Plug 29510885 (7/8" x...

    Companies used to supply things as such for just these occasions. I think Japan still offers some. Thanks for the thought.

    M1078A0/ Allison MD3070/ Drain Plug Threads

    Gentlemen: I said to myself, why reinvent the wheel?, Come to somebody who has already experienced this. I removed the drain plug on the Controller Box on the bottom of the transmission and drained the transfer box. I changed the filters and reinstalled the drain plugs to find out that I didn't...

    Niehoff N3030 Regulator/ M1078/ doesn't have flashing light capacity

    Please instruct me...... What is in conduit rating versus free air ratings?? I mean I know what the name implies but how does that effect the amp ratings on small wiring such as what we are using? Thank you? The other thing I am dealing with is the unknown future load, incandescent or LED, what...
