100 Amp fuse - quick verification
Discussion
Convinced this is the case as it's similar to what happened the last time this thing went, just want some verification before I tackle tomorrow:
Battery flat, jump starts fine and runs whilst connected to another car via leads. Remove leads, car dies within a minute - Power Supply error and 7 volts.
Clearly the battery is OK as it charges from a charger or another car, but not the car itself therefore the alternator isn't charging the battery - hence the fuse theory.
Or the alternator could be shagged...that'll need some probing. Check the 100 Amp first?
Any easy way to check this without removing the airbox?

No its an airbox off job. There is another 100a fuse in the footwell against the bulk head that is easier to check but this is not in-line with the alternator. Might be worth replacing with a 125A upgrade as well as moving the fuse holder to the wing so its not a PITA to get at.Battery flat, jump starts fine and runs whilst connected to another car via leads.

Excellent. The only other possibility I suppose is the alternator has failed or the drive belt to it has failed...?
The power steering has totally failed as well (which happened last time) - is this electric btw?
Done the 100A before, on the side of the road 200 mtrs from a campsite at Le Mans...

Yes the PS pump is electric. The 45A relay is in that grey holder by the oil tank. Its fused (80A strip) in a holder in the battery box. There is also a fuse for the PS relay on the main fuse board I think its a 12v switch feed but I need to check. If you remove the PS relay you can check if you have juice to the supply side of the relay with a multimeter. If you unplug the connector to the PS pump you can check the load side of the relay to see if the pump is kippered or not.The power steering has totally failed as well (which happened last time) - is this electric btw?
