This is more a question directed to electrical guru george kujanski but anyone is more than welcome to chime in as well.


Here is the deal: I am rewiring my last convertible: '63 Lemans 326 V8 engine 2 speed transaxle. I untaped the original V8 engine harness only to find it badly melted, (see photos). Seems the main power supply wires running to and from the amp gauge got very hot. More than 1/2 of the run (Brown wire) starting at the dash harness all the way to the hot lug on the back of the old alternator is completely fried.

My plan is to upgrade this car to a modern 63 amp 10 SI alternator as well as doing away with the amp gauge altogether. I am going to install a "gen" light and possibly a volt gauge instead.

My question is this: I have noticed that nowhere in the original engine compartment are there any fusible links, was this a cost saving measure ?

Should I add in one or 2 as a safety measure as I am replacing most of the main power supply feed wires anyway. Where would be the best place to put them? At the 12 volt "+" function block on the driver's side fenderwell or at the output on the rear of the new alternator? I am going to do away with the yellow wire that runs from the rear of the old amp gauge to the junction block and simply run the 14.2 volt output wire from the new 10 SI over to the junction block on the fenderwell. This is how most modern (1980s era) GM cars are wired, does this sound about right to you?
