    What's anyone's thoughts about installing a fuzeable link in the battery wire. I'm doing a new harness and found this may have helped the old ariganal harness from melting.

      Uhhhhhhh.....that's a little too technical for me. Can you dumb it down a little? Thanks

      On a serious note, yeah that's a very good idea.

        Put it where you have good access and won't burn other wires. What amperage fusible link are you considering? 440'

        Fuses are available in any size if you would prefer a fuse over a fusible link. A link should be several wire sizes smaller than the wire you are trying to protect.

        IMO.....fuses are the most common, most reliable and economical method to protect an electric system considering the load device (amperage) and wire size supplying the load. But several factors that should be considered: how many amps will be consumed by the device; wire size, power source and overall voltage of the system. The National Electricial Code is a good guideline for sizing of individual components. Fuse sizing's "rule of thumb" has generally been 1.3x to 1.5x the amps consumed. These would be considered standard interrupting times. A "slow-blow" or time delay types could also be considered but at a lower value, say 1.2x to 1.4x amps. The absolute best type of fuse is the "current limiting" type that is capable of interrupting very high currents from a large power source, in this instance the battery. Look ar the Buss Fuse web site: www.bussfuses.net for sizing and selection information. Or...there is always your next door neighbor's cousin's sister's husband's uncle's best buddy's friend who re-wired his 1939 Huppmobile when he installed a Hellcat drive train....... Just my opinion of course...

        This is good stuff you guys. Not sure what amp link yet or where to install. More thought and study. Thanks for the comments

        Original protection is between starter stud and bulkhead to protect from any short coming after the bulkhead. Anything on car is from that starting point.

        Any protection between batt and the starter relay will require a fuse link big enough to handle the starter motor solenoid ( which is not low ). This would avoid smaller loads shorts what would take LONGER time to burnt for the fuse link and will make a bigger damage where the short happened.

        Not to mention the size of the fuse required for the starter motor wire itself if you are thinking on THAT wire.

        Now you know why is there.

          Once again, totally obtuse, vague, incorrect and meaningless information (?)...... supply some ACTUAL documented information using NUMBERS / CALCULATIONS to support your position.....
