Thanks a lot for your help. I will have a close look this week.

If both tanks are full, yes, they hold the pressure. Or let's say, they keep the pressure for 24 hours. Thanks for the hint. I will have this week a close look, didn't have time the weekend. I will post the results.

So, I had a close look at the two one way valves. Strange think, in one of the valves wasn‘t a spring. Just to get sure, this is the problem, I switched the valves. But the problem remains the same. Anyway, I will get to two valves and will see what happens.

Thank you, I will check it

Hallo, I have a strange problem and wanted to know, if this is normal, or what could be the issue. For the tests, all air tanks are filled up. 1) If I drain the primary air tank, the secondary air tank keeps it's air (I guess, this is how it should be). 2) If I drain the secondary air tank, the...

Normally 2 batteries are parallel to 2 batteries in serial (I hope you can understand it). The 12V worn down between it. So 2 batteries are getting more discharged then the other two's. I know the truck is equipped with the Niehoff Battery Control device. But in my opinion (and the opinion of my...

Why shouldn't it be a good idea? The M1078A1 has an alternator with 24V and 12V. So with the 24V I charge the two big batteries (2x12V serial) and with the 12V I charge the small batterie. And for the truck it isn't a problem neither. Both systems are getting charged without a problem. The...

I diveded the 24V and 12V circuit. I wanted to get rid of the 12V drop of between the two batteries. The charging of this system works without problems. And I never unload the 24V system with the light or radio.

Nobody?

Hallo, has anybody the serial number of this Nason oil pressure switch. It is for a M1078A1 (2003) with a cat3126b engine. Thanx

So, I send my ECM to a repair shop and they can repair it. They said the internal power supply is damaged. Looks like I got a voltage spike from somewhere. And now I come back to my first question. Can it be, that this piece right from the ECM it there to protect the ECM?

Sorry, that is not correct. My ECM is in a repair shop an the internal power supply is damaged, not the battery. And this happened as one of my 12V batteries had an internal shortcut.

Thank you. Interference filter for what? To protect the ECM? My ECM is dead, because of an internal shortcut from the batteries. I know interference filter with AC current, but not with DC current. Does anybody has the serial number? Then I would try to find a technical data sheet.

Hallo, sorry to ask you. But knows anybody, what this is? It is right from the ECM and it isn't connected to anything. I mean this thing with the serial number MFR-.....??? Thank you

@fuzzytoaster Just another question. Which number of the ECM do you mean. The serial number should be 206-2700-02. And under this number, I can find other ECM in the internet. And it is clear, that I must programm the ECM new.

Yes, it isn't easy to find one in Germany. Perhaps I am lucky, otherwiese I have to oder one from the States (cheaper anyway!). Can anybody recommend a good service?

So, I know more. The EMC is dead. Nows anybody a used one for my truck?

@Ronmar If it isn't a fuel solenoid, what is it else? I thought it's for shutdown the engine. So I should be under power, if you want to start the engine. @fuzzytoaster I use a Cat Com 3 Adapter (317-7485) fron China and ET 2015A. On Monday I get an Cat technician and he try to read out the...

The circut breakers I allready checked. They all worked. I also checked the power in the harness plug of the ECM. I get there the 24v DV.
