[C38] up-grading electrical system

[Max Soto]

Hi Patrick, the modification that Tom just mentioned is also recommended by Catalina. 
I will say it is a mandatory modification instead of a recommended one.... 
This was one of the first mods that I did on Estancia as soon as I bought her..
Regards, max

This charging wire should be fuse or breaker protected on both the battery and alternator ends.

The plug WILL eventually fail with the high amperage of the alternator going through it and it will very likely cause an electrical fire as the plug burns up the remainder of the harness wires causing dripping, flaming wiring insulation into your engine compartment.  This could seriously degrade your day.
