A 50W headlamp will limit current to 5 amps or so.=C2=A0 Just about any wir=
e used in a British car harness will carry that easily enough.=C2=A0 If you=
 are concerned about the wire size you can place two headlamps in series to=
 limit current to 2.5A.=C2=A0 A short to ground will just look like a groun=
d connection to the headlamp.

 Dave,

This is brilliant (figuratively ANDliterally) 8>)

But is this safe? =C2=A0Couldn't itmelt wires if there is a short?

This is a really great idea I neverhear of, so thanks for sharing!

Best tip of the year!

Moose

The trick I learned is to replace the fusewith a headlight. =C2=A0The short=
 will cause the headlight to glow fullbright. =C2=A0Once the short is clear=

 now it is safe to reinstall thefuse.

OK, I'm sure I'm missingsomething here, but I figured I'd ask.

My Jeep had a short circuit and blows a fuse if I turn on the lights.

So I remove all bulbs on the circuit and try again. =C2=A0Blown fuse.

I take some other items off the circuit and try again, blown fuse.

Moving around and trying different things, blowing fuses all around.

I found the short, fixed it and all is well.

My question is, is there a way to do this without having to blow fuses?=C2=
=A0I'm guessing a meter should show 0ohm resistance if there is stilla shor=
t, but I was not getting a open circuit.

Any ideas so I don't have to go through a hand full of fuses next time?

Thanks.=20
