Re: No power at fuse box
As I mentioned in my earlier post - the diagrams I have don't have any detail so I can't really help. Generally, the Maxi fuses handle the larger power inputs from the alternator and the battery, then into the engine fuse box for distribution.

Re: No power at fuse box
Well that would certainly cause charging issues, but if the battery has enough power in it, then it should supply power to the engine fusebox and then on to other components. An example - my alternator / accessories belt snapped, I was unaware of it until after about 18 miles later the steering felt a bit 'notchy' and the battery light indicator came on. So my electro power steering system operates on battery power alone and so did everything else without the alternator running.

So a faulty earth in the alternator should only really affect the charging circuit, not the power getting from the battery to the fuse box.

Re: No power at fuse box
Are you sure that the cable to the alternator is an earth cable? The alternator is usually earthed by being bolted to the engine. The big cable(s) to the alternator are usually live battery feeds, and if there is no voltage, there, indicates a problem with a maxi-fuse.

Re: No power at fuse box
Well if it's a Type 1 Board as per that link, then that would indicate the Engine Management ECU (30A). You won't start the car and will get immobiliser issues if that isn't working. So have you changed the fuse and tried it then?

Re: No power at fuse box
just found this
Over the last 3 months it has been used less frequently maybe once a week for short journey, 15-20miles. Don't know if that is significant or not.
However, it was used one day last week with no problems and the following day I wanted to remove from the garage..upon trying to start it the error message "Engine Immobilizer Fault" appeared on the dash. It will not start but turns over ok. From what I can glean from various websites and a conversation with a Peugeot technician, this issue is related to the car not seeing the correct key. Is that correct??
I've tried several things;
New battery in keyfob [both keyfobs exhibit the same issue]
Disconnected vehicle battery and reconnected using 3 minute rule and following the BSI reset process at least 6 times
Tried to jumpstart from the Vauxhall Vectra
Flattened the battery and recharged to full
New Peugeot battery
.....all with no luck
The keyfobs all work ok and appeared to be synch'd as the central locking will operate correctly
The position is now that the car has gone into "Economy Mode Active" and still will not start. It doesn't display "Engine Immobilizer Fault" anymore but I suspect that it is hidden behind the Economy Mode message. How do you get the car out of Economy Mode Active to get back to my original fault message
fault fix
Trace multiple wires as per a previous posting on this site for a No comms issue to the ECU.
Turned out to be the wire in the previous post. Engine bay fuse box: black plug; pin13 gets switched to earth via pin 3F2 of the ECU. This tells the fuel pump etc to fire up. Put a temp wire in to see if it cured the fault and fired up first time!!!
At the very bottom of the wiring loom within its plastic conduit beside the bottom of the air intake, this red/white wire was broken. Reconnected through and all ok!!!
