Major Fuses and symptoms.....

[ChazUwe]

Right in my quest to be prepared I have a long list of spare fuses , relays etc. But I was just wondering if someone could confirm the likely symptoms if one of the 3 main fuses go:

100amp fuse under airbox - Are the symptoms similar to a failing alternator or dodgy battery?
80amp fuse in passenger footwell - Issues with power to the dash etc?
Fuse in battery box - Failure of PAS?

General strange running/electrical issues - Often caused by bad earths in the battery box, passenger footwell and engine to chassis behind front d/s wheel?

Also could someone be kind enough to message me the resolution should you get locked out due to flat battery or other alarm/locking issue! Better to be pre armed with the knowledge rather than messaging when stranded somewhere particularly inconvenient!

Thanks for any guidance

Great thanks guys, at least if I have similar problems I will know where to start! Have plenty of spare normal fuses and midi fuses, just hope I don t need to use any

Thanks Shep, although wouldn't be impossible to get hold of the spare in the boot of the T350 I would rather just keep a more accessible spare in the glovebox! Very good tip
