    M1078 Battery Conversion

    One last though I'd like to add since you are Fire Services related, since the truck isn't always running with the extra room you can install on the back wall a small 2 lead battery charger {3 or 6 amp) and install the 110 vac plug where the NATO connection is. If you want an Auto Eject you can...

    M1078 Battery Conversion

    RonMar said well. I personally use an Interstate threaded Lugs/ They have a 1000 crank amps a piece/ Without looking I think the cable is 2/0 on both hot leg and ground/ No trouble whatsoever.

    M1078 Allison HD3070 Shifting Problem

    So the truck is shifting now. The fix was quite easy once you know where to look. The problem was at the KeyPad. After finding that I had an active code on the TPS, and watching the video put out by Ronmar, I found that the TPS was good and that between The TPS and the Keypad I had a problem so...

    M1078 Allison HD3070 Shifting Problem

    I've got to get back out there and check continuity/ Thank you for the schematic/ It is much more concise than the TM schematic/ The other thing I have had happen on trucks is that wires shrink or get stressed and actually just pull out of the connector enough to leave the circuit open while...

    M1078 Allison HD3070 Shifting Problem

    So I went to my truck with the new found information and just knew I had this thing whipped and low and behold I was wrong. The TPS itself is working fine and with in the ranges required so I set about to calibrate and nada. Now this of course leads to more questions and NO, not of yet have I...

    M1078 Allison HD3070 Shifting Problem

    I will give the problem first and then state what I have done for diagnostics. Problem- Transmission when put in drive lights up with 7 gear showing in left window and 2 showing in right window. Drive and will not shift to 3rd even when tached out. Stop- Shift it manual in to 1st- it goes into...

    M1078A0/ Parking Brake Release

    So I wasn't so quick to get back with you how that all turned out. I apologize. It turned out to be the Relay Valve. When I removed it from its perch it was quite plugged. They you weigh it out and say I could try cleaning it but the cost isn't that terrible versus the inconvenience of location...

    Well Sir, you get the Attaboy for what it is worth. Thank you for sharing the information, the videos, the knowledge, the time. I'll let you know how this turns out and the door has been opened to diagnostic playing. Lugnuts

    M1078A0/ Parking Brake Release

    That's brilliant way to check that, thank you. As far as the Relay Valve/ Anti-Compound Valve is there a kit that you can pull the whole valve out and rebuild it or is it a valve that if one side fails you replace the whole valve? The truck is 40 miles from me and I would like to minimize my...

    M1078A0/ Parking Brake Release

    That's a great explanation, thank you. So when the Parking Brake Control Valve is pulled up to release pressure, if you hear the front quick release air exhaust and the lights on the dash come back on telling that the brakes are applied then if your parking brakes are slow to release it must be...

    M1078A0/ Parking Brake Release

    After reading my air line schematics available on Steel Soldiers and after going to YouTube to view RonMars Air Component Video (which by the way is excellent even after the 4th time) I am turn for help for confirmation. My parking brakes are taking 20 seconds to fully release. I suspect it is...

    Gauges and Sending Units Caterpillar/ M1078

    Without looking at a wiring schematic does that mean if the alternator excites that the sensor is good or is there 2 parts to the sender. A ground and a potentiometer for the gauge? Is that sensor also located in the middle of the engine block on the left side?
