I have a blown 30 amp fuse hanging off the plus pole of the battery. It has burned pretty badly - the fuseholder has been blistered and the insulatio on one wire is melted.


I have no idea what this blown fuse is for.

 

How about tracing wire back to sourse. Is the wire bound in with the rest or standing alone. Just wondering if its a connection for Taxi appliences and the disconnected wire has earthed.

 

I was hoping to avoid tracing the wire as it could go anywhere - hence my post.


FWIW it is a green 30amp fuse.

 

what colour is/was the wiring either side?, can you post a picture?

You need to be very careful about "buckshee" wiring direct from a battery + terminal. No proper auto-electrician would ever do this as a fault could result in a fire destroying the vehicle. Insurance investigators would discover any buckshee wiring and possibly refuse to pay out. Fortunately the amateur electrician has at least put a fuse in circuit.

You should for your own peace of mind FULLY investigate ALL this wiring, and probably remove it. Getting an electric shock is impossible from a 12volt circuit, but starting a fire in a 12volt starter-battery circuit is very possible.
I speak as one who has lost a car (write-off) from this factor. It was a Citroen C4 and caused by the ABS unit under the bonnet/hood. Fault in that case was the manufacturer.

That did not go well. Are new members not allowed to edit posts or post pictures?

Hmm..that's not standard by any means. Remove the wire from the battery terminal to prevent any further chance of a short.

To find out what it was added for you'll have to hand trace the wire or find something that isn't working anymore.

Thanks, the only thing I am aware of that is not working is the AC cooling.
I was hoping I could just snip the wires and replace the fuse and fuseholder, but I think I will follow your advice, Richard, and disconnect it entirely. Quite the puzzle - fuse blown like no other yet pretty much everything works fine.
