electical problem

Thanks for your suggestions guys all good points to help solve the problem . Was workin today so no time to look . Herman fuse 30 looks good also fuse 6 which supplies power to management relay power on both sides .Itomis good battery holding 12.8v terminals are clean and tight. Atomsplitter I'll check what you suggested tomorrow. Something I was thinkin is it an earthing problem somewhere in circuit ? We'll see .

Also , its a little pain to check....Where the relays plug in under the side covers, check the tension of the slide on connectors inside the loom plugs....i've had a few loosen up over the years....also check for discoloration of the relay spade pins.

I've swapped the relays before, has anything changed? I also tend to believe that there is a bad contact somewhere. All that remains is to find this place.

I'd be swapping relays around to see if the problem changes, better still replace them one by one with new.
Also checking condition of pins on ECU plugs, could be poor connections due to green rust etc there giving weird problems and codes
