Doug,
The best bet would be a separate in-line fuse.
I have had engineers from Bluebird school bus call and ask me what the
length should be and I have looked in the SAE specs and have found that it's
a lost art.
Fuseable links require a measurement of ampacity vs. length of wire. You
would also need to figure the guage of the wire in the equation. Best bet is
an in-line of some amperage to handle the high beams.
Just my .02

Subject: Fusible links for a Spit?
I was meditating on my Mk IV's wiring diagram, and I
noticed that the the headlamps are completely unfused
(except when you use the hi-beam flasher on the stalk).
In fact, there is a lot of wire in the harness that is
unprotected, where a short would cause an immediate meltdown.
So I was thinking: It would be nice to have one or more fusible links
as close to the battery as possible. Has anyone seen a good product
or design for doing this? I was thinking of some sort of block
mounted on the firewall just behind and above the starter relay,
where a short wire would go from the battery post of the starter relay to
this block, and the various circuits would all connect to the
other terminal of the block. Does this make sense? Would one fusible
link (50 amp?) be enough? What about the alternator connection?
Thanks,
Doug Braun
