put 24v direct to the starter.
or,
The most common problem when jump starting a lorry is not connecting up to the batteries correctly. If you connect them in parallel rather than series, you won’t get the umph. The dash will light up to make you think everything is the way it should be.
ive had 24v direct starts like a dream 
, but the problem started before jump starting, it did it just turning over on the key
its in at keltruck
So your main power line to the starter is ok if it starts when you give a positive to the solenoid exciter cable.
The starter motor earth is via the housing metal, power 24v via the big cable, and the exciter cable is normally dead, but gets a 24V signal when you turn the key to start the engine. Normally the ECU/relay etc is in charge of sending that signal, after getting the message from the key.
When you give it a cable from the positive of your Anderson plug, your just going direct to source. You could also just short between the main starter cable and the exciter cable. A length of lead and a push switch will be an emergency fix for now.
Follow the exciter cable back - is it broken at any point? Is the terminal corroded? It’s very likely a brake in the cable in the loom where the cables bend into the cab.
When you turn the key to ‘start’ location, can you hear the relay click in your fuse board? Try swapping the relay. Check if the cable from the relay goes live when you turn the key. If it is, you have a cable issue, if not, an ECU or relay one.
The ECU will only send a start signal if conditions are met - they vary truck to truck. Normally you need the cab lock switch active, some need to have the brake on, see the box out of gear etc - any of these signals being lost will prevent starting.
Let us know how you go!
its had a new ecu and starts bang on, but while it was in told them to go over it front to back, its had the full monty, cant wait for vosa to pull me and try and find a fault 
pick her back up monday dinner then down to reading at 3ish, she should be super smooth 
jobs done
diff seal
crank seal
cab mounts
ecu
key set
header tank
new air bags
new clutch kit
night heater fixed
new seat
new bonnet cable
thats just of the top of my head 4 oil leaks all together

with that list, it would have been cheaper to buy a new truck 
its now as good as a new truck for less than 1/4 of the money

That’s main dealers for you they will always try to maintain to new standards if you or you pocket will allow them to, it’s a long and worrying list and shows the difference between the previous hauliers level of " serviceable " and Keltrucks, as an aside I bought a Scania164 580 just over 18 months ago that was a 1 owner driver truck with full service history from the supplying Scania dealer from new, it has never put a foot wrong in 18 months, never had a breakdown or cost me a penny in lost work and has covered nearly 200,000 km in that time, it’s 12 years old with 1.2 million Kms and does almost everything my newer truck do ( non LEZ ), it is still main dealer serviced still using only genuine Scania parts and I feel that’s the main reason for its ongoing reliability well that and the fact it’s a V8 Scania of course 
I’ll tell the sorry story of the XF 480 that has cost me over £11k in repairs and breakdowns in 8 months when I have got over the shock of the diff failure it suffered in Scotland just last week 
, who would be a small haulier eh !!!

Don’t mean squat Si, as you know even an MOT only states that at the said time of the test everything was ok 5 mins down the road anything could happen… don’t count your chickens Si you just know you’ll get bit and since there are Vosa members etc on this site and Know who you are and company and the trucks you have, well just saying fella.
PS when you selling it now you got it fixed then

just means i know the truck is spot on as far as i know, wife hates me because i need every little job doing on the trucks lol, and im just sorting a maintance contract out with keltruck, so all being well everything should be sweeeeeeettttttt

bloody scania
not claiming to be an auto elec but can do a bit the old man f90s used to do this and it was always the main earth mounted on the gear box the bolt just came loose same symptons as yours got to be be an earth somewhere fella by the sounds of it

it was the ecu, its had its 1st run out tonight after all the work and ■■■■ does it feel better, anyone thinking about having there truck remapped forget it, its this that has caused 90% of the problems

Si why or how has the remap so caused 90% of the problems?? maybe you could shed more light on to this please… or could this be Scania talk/fitter blaming the remap to the problem, as a fair few 480s and 470s 6cyl R series scanias have a problem with there ecu"s Scania no this exists but turn there backs on these so called ecu problems, and who did the remap ■■ on the truck,
cheers
It sounds more like the usual “I can’t find the problem, But if i tell you it’s the ECU and charge you a fortune, It’ll give me time to find the broken wire whilst ripping you off”.
Everytime i’ve been told it’s an ECU fault, I run a mile and sort it out myself. Fitters trying to play at being mechanics.
Old scanias have a stupid start control solenoid in the main fuse box that goes goosed.
Mind you scania dont seem to have progressed much. Still a pile of old fashioned crap.

to steep a torque curve, know its back to standard the truck feels miles better, little slower up the hills but just feel better, might just be that mine was opened up to much, 480 to 560, the springs on the clutch had started to break up, on a 1yr old clutch, imho it was putting tomuch strain on the gearbox
when pulling up hills with the old ecu the engine failure light would come on along with the high emmision light once over the hill it would go off, but it started to stay on longer, and then it got to the stag where the emmisions one wouldnt go off
its had 2 runs and still spot on

ive had the best sparky around here on it for a full day even he came back to the ecu , not a broken wire anywhere

As long as you know him and trust him (hard to find). I’m sure you’ve come across plenty of the sorts i’m on about.
