you guys that ran your own harnesses, did you install a fuse/fusible link inline with your alternator and starter battery cables?

It is good practice to install a fusible link on any high current wire that could become chafed and short. If it chafes somewhere downstream from the power source and shorts to ground, the fusible link will melt and create an open. This should be done at the power source.

My 05 LM7 came with a fusible link between the alternator and the drivers side junction block. Since that did not prevent an issue with the battery from cooking the wiring, I added another fusible link between the junction block and the main fuse panel.

I used the stock fuselink in my turboBuick/S-10 swap and added a 120A circuit breaker in my LS/Maverick swap. Don't think I'd try anything on the starter cable...

for the ls1's, what amperage rating are you guys using?

No fuse or link on my. Just some 6ga (overkill but it what I had) something pretty extreme would have to happen for my wire to touch anything though. Prolly wouldn't be a bad idea if you are at all worried about it.

I replaced the fusible links with in line fuses. There is no good reason to run without one or the other. Have one off the alternator and an one in line to the battery.

You size the fuse/fusible link to match the wire size. Yoiu can find tables of wire gauge amp ratings on line. I did match my alternator fuse to the alternator rating (85 amp) since the wire is much higher rating (4 gauge)

yeah i over killed my wiring... 2/0 gauge for the battery and 4 gauge for the alternator.
