214 Red wire from battery negative (1993 L reg)

#1 Post by 214CONCERTO216 » Wed Aug 21, 2019 12:46 pm

A short length about 9-10" with a fuse has become detached from the negative. What is its purpose and where should it be attached to?

That sounds aftermarket to me.

Fuses on the Neg side are very unusual for a car, not so unusual in marine electrics, are you sure it's not become detached from the Pos and came to rest near the Neg ? Red wires are usually Positive in Pre-fusebox feed Automotive usage. Various colours are used for various accessories/functions Post-fusebox. Black is Negative.

Usually fused wires direct from the battery are powering something big drain through a relay like Spotlights, Air Horn or Boom Boom Sound System.

A pic would help.

Can you follow the wire to see where it goes?

No. It is completely detached.

So it is attached to the battery but goes nowhere?

Does it look like a facyory fit item or aftermarket? Is there any system on the car that doesn't work?

It was definitely attached to the negative battery lead before it became detached, but it was not attached to anything at the other end. Everything seems to work, because I have tested everything in preparation for the car's MOT.

Is it working? = leave it alone
It’s not working = try duct tape
Did it work? = try cable ties
Did that work? = you didn’t use enough cable ties

If one end was detached already and now the other end is detached too, but everything works, then it sounds like it's not needed
