Thank you/ I printed it out and I will give see what gives tomorrow. I have a path I am following now.

So I read how to do this and Guyfang stated if this didn't work to write back. Well it didn't work so I'm back. I put new seals in the filters/ Did as per Operators Manual said /Switches and lights worked as mentioned/ No fuel Afterward I looked on the electrical schematic and decided there...

How does the battery equalizer system work? I'll claim ignorance.

So in the end I have a happy one. After checking battery condition, after cleaning connections from alternator to batteries, I still had not my repair. So I checked Voltage Drop going from Alternator to Polarity Box. The numbers were bouncing all over. Some believe in Divine Intervention and I...

Thank you. I did load test them but tomorrow I will get to work on this seriously, I will swap the batteries and I checked the schematics and as I figured the Alternator is connected on the battery side of the polarity box. Going to definitely check connections.

Thank you. I am going the same route of diagnostics, Kinda sorta. I got to thinking about load and diodes in the box. I am tomorrow going to look at the schematic to scrutinize where the connection is for the power from the alternator to go back to the batteries. One side or the other of the...

In an overall view of what you have posted is it possible to check the alternator by removing the 12 volt leg from the alternator, starting the truck, and measuring the voltage at the 12 post of the Alternator? That is, if is 28.2 vdc at the 24 volt side it should be by theory 14.1volts at the...

Well, thank you for the response. The instruction was invaluable. The rebuke was noted. And to answer your question, No I hadn't looked in the TM's but now I know in which issue to look. Thank you Guyfang, Lugnuts

Thank you for the response and more diagnostic clues. The voltage at the battery of 12.4vdc was the same at the alternator/ The SCRs are probably a rectifier. Please clarify/ I will check the other things and get the year of the truck./ I was wondering about the polarity box and now I know I...

MEP 005A Thank you for the reply

Gentlemen: About 2 weeks ago I had a generator load up with water on the fuel side/ So I removed filters, drained the injection pump, cleaned the lines and checked my diesel supply ie I cleaned the tank/ So I went to start it and it seems I lost prime and need to replace the quad rings at the...

Gentlemen; I have a charging problem and it goes like this/ The Battery configuration is 2 group 31 batteries/ The system has been very functional for over a year/ Now I have the 12vdc side draining while it's running and my charge rate on the 24vdc side is acting like the parasitic draws we use...

I'm in and Thank you

Thank you/ I guess I'll pull it down and take a look. Next task I have is the wiper linkage and that looks like a real chore. The manuals are really difficult sometimes to get the information you are looking for. Happy Thanksgiving.

I'm once again turn to the folks that have worked on these critters. I have a PTO winch that will not work. The problem is electrical. All the switches are good, good power source, and the PTO is engaging and the light on the panel shows it. The problem I am having is finding the connectors to...

Sorry to take so long answering. This is not an involved question but the answer takes some thought and time because this was the early part of my search. First off my board wasn't bad it was a bad ground. The question I would ask you now is do you have the electrical schematics for the A1?? The...

In Please

So here's what I got going. Thanks to Ronmar I have a working Hydraulic Control Box and Air Pump. So I set it up to test flows and what I speculated would happen when I flowed oil. The Controller worked great and gave me a platform to work from for when I get my other Box home I can figure out...

Thank you for the clarification Ronmar. Can I contact you on a personal message as to what you would consider? Thank you for the video link

I am unclear if this is sarcasm or if you have one to sell? I take it is sarcasm but...? If any one has a Controller Box perhaps an extra that they would like to part with then I am most certainly interested! LOL! I would say smart ass but some might be offended.
