Seems like the solution is finding the best price right now. What have you got for a solution??? I'm listening! My problem is I'm at the beginning of Brush Fire season and Annual Preventive Maintenance and as long as they don't fall off the truck isn't coming out of service! But great...

So I have returned with the report/ After pulling said box I opened up the compartment and found how nice sized a modern day ECM is but with the box open you have the possibilities of repairing itself. I have attached 2 pictures of the A5 Card and I am asking if the R3 resistor would prevent the...

Thank you, that is a start/ Memphis Equipment also stocks them as a whole arm/ I am also try to get the best price/ Do they make an insert?

I am finding as I get older that it is expedient to humble yourself and claim ignorance rather than repair and find out how this stuff is really assembled. On these torque arms I notice that the ends are constructed differently than the M35/ The M35's the Bushing get pushed out and that takes...

When you say the A27 Box where do I look in the manual for the explanation to the A27 Box? Is there a drawing show =ing where the A27 Box location/ Any recommendations on who to contact for a float?

There were 2 floats on it/ and with s2 in run, the s7 in the up position, the CB1 pushed in there was no voltage what soever at the J33 plug that goes into the Floats

Thanks/ Literally on the very back/

So here is what happened with that test Holding the J33 in your hand, stick in the first paper clip into the A&B pins of J33. This should turn on the pumps, if the wire harness is good between the J33 and the pumps. Then place the second second paper clip into the C&D pins. This is the idot...

Damn your good! I will get back down there and try the jumpers on the plug/

That information on the fuel system is great! First off the handle was in the wrong position. I followed the procedure you outlined so well and I did not get fuel/ The pumps never turned on/ So I dropped the strainer bowl and removed the strainer (now in your procedure you said to removed the...

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...
