Electrical Problem

[octopush]

Went to start my aautocruse starblazer 2004 and found that it turned over but would not start I then went inside to see what voltage there was in all the batterys there was no movement on the meater I put a test meter over them, all fully charged went to turn the 12 v lights on and nothing pluged the van into 240 all worked van then fired for a second then cut out.
all the dials on the dash keep flicking up and down.
The van worked ok a week ago.

Any ideas of were to start looking for the fault would be helpful.

I I do not think it has anything to do with the ECU as it is the leisure batterys as well as the starter battery

Thanks Rob

All the batteries probably share a common ground (earth) which sounds like it has a poor connection somewhere.

The earthing points are all good.
it dose look like an earthing problem.

Try putting a jump lead from your van battery negative to a good earthing point on the chassis, this is a quick and easy check for earth faults

I helped a French camper in Belgium who had a similar problem, all it needed was a good clean up of the positive battery terminal. Even though he was convinced that it couldn't be that simple.

I would remove all terminals give the a good clean on both sides refit back on and give a light coving with Vaseline.

???????? That makes no sense.

If all earth points are good how can it be an earth fault ?

Back in the day when I had a Starspirit it was the battery positive terminal that was loose. As it is quite difficult to access I suspect it wasn't fully tightened originally.
To tighten properly you need to remove the battery hold down clamp then disconnect the battery negative and drag the battery forwards so you can get a 10mm spanner on the terminal clamp safely.

It's all sorted now.

It was a number of things.

A 20 amp fuse had blown that was hidden with the leasure batterys
also I'm sure that the vans main starter battery is playing about.
I disconnect the starter battery last night connected it this morning and it started straight away.

Something did go wrong but finding why now it's all working is going to be hard to find.

Can not understand why all the dials flickered and the engine turned over fast but would not fire.

Thank you all for your help.
