No starting Cerb 4.5

[jaydom]

Hello everybody,
Yesterday, after diner, my Cerb hadn't start.
Everything seems to be correct:
- lights are working
- stereo too
When i try to switch, everything is correct
- normal beep Heard
But nothing, no noise except the fuel pump that makes a usual sound.

No click by the starter that seems not to Turn..

I manage to start the Cerb by pushing it.

It drove perfectly.

This morning, nothing again.

I have the battery disconnected but nothing.

I will call the garagist monday but i would appreciate you help me a bit to gave a "clear" diagnostic.
- CAN it be the big fuse?
- is it only the starter that died?it was working perfecly before (only one try AND THE car was starting).

So?

Many thanks in advance!

Tricky one Jerome. I've never had this problem on mine, so it's difficult to offer advice on what to do. Check all the obvious things first, fuses and connections. Check all the connections on the starter motor, and the Big Fuse.
Hopefully someone else may have some better ideas.

Swap the yellow relays around on the fuse board number 52 is the starter, if you have a multimeter remove the panel below the windscreen, locate the starter on top of the bell housing passenger side, find the little ignition control wire (comes from the solenoid to a grey plug with a spade crimp on)unplug it and test for the 12v at the car end to an earth any where on the engine is fine when the starter button is pressed, that or give it a direct feed from the battery which should turn the starter over.

Probably immobiliser. Try holding starter button for 30 seconds.

Best way to diagnose is under bonnet, unplug the wire going to the starter motor solenoid (really easy to get to, a spade connector into a plastic block which will be somewhere near the big fuse). Put a multimeter on it and see how many volts it shows when you hit the start button. It should go to 12V pretty quickly.

If it shows 0V - you'll need to work out why - could be a fuse or something
If it shows a few volts, maybe slowly sclimbing, then it's the 'standard' immobiliser fault.

Thanks to everybody for answering me.
It was only...
A little green fuse of 30amp!
I changed it and everything is ok!
So, as I'm a New owner, im going to buy several fuses to have always some in the cerbie!
