Don't worry that's the air brake electric schematic I'll post the schematic for the High Pressure (Hydraulic Brakes) later this evening. The resolution on the originals is poor so I'm having a hard time reading it. But nickirl is doing a great job with getting me the correct diagrams.Dam.. I cant make heads or tails of that schematic...

Our 10 reg 6490 pulls like a train and punches above it's weight, however it is not aging well and by the time we get past 6000 hrs I think it will be knackered or the error codes will be stacked so high on the dash it will go into melt down

I run a 6000 hr 04 6485, its a good bus, and it will do a lot more.

Yeah, they downloaded perfect!
The only downside as you say is the diagrams are not good quality even on the originals. I have found the page relating to the brakes and printed the diagram I've the highlighted the path current takes to try and get an idea of where to look should the problem be electrical.
Thank you to everyone for their input and nickirl for his valuable diagrams.

Not gone out to the tractor yet, was hoping my nitrogen accumulator test equipment would have landed for this weekend but no such luck.
Did you change the filters as part of a service, or due to the filter light appearing. I'm just trying to build up a picture of possible causes. As always with a lot of these faults. Check the earth to all the controllers and the battery, you'd be surprised what problems a poor earth can cause. Next bit of advice, don't take a sensors output as gospel, prove it is right by pressure testing with gauges, then you have a better picture of what is actually occurring.

Thank you for the heads upyou two are talking about 2 different tractors
, this changes the above statement completely. As the Dyna VT transmission doesn't make use of the HP brake valve that is used on the 6480 so I shall remove some of the previous post to reflect this.Ok, thanks for that. The filters have been changed due to a whole new gearbox and casting. And it's only done approx 12hrs since it's been back. I will check the earths tomorw and see what's what... Thanks for the reply though.

Just read your MF thread, hopefully the filings generated from the casting wear hasn't spread through the hydraulic system yet again, to knacker the pump or fill the filters full of rubbish. This sounds like a job for the dealer to re-investigate, not sure forum advice is really an option in the case. But I stand to be corrected?
Yea, will be onto them first thing tomorw, couldn't get in contact today. I was just trying to see if the t151 was and could be connected to the light Hyd light etc... Hopefully it will be nothing.

had this fault on a 6475 before found out it was the wiring harness at the rear of the cab that was at fault the corrugated conduit had rubbed through the wires just below the multi plug worth a look this conduit causes many a problem on MF's especially if dust gets inside it there was a tech bulletin issued about it
