No it is protected with circuit breakers and spade fuses. I'll email u a picture of the schematics for all 379 model peterbilt that was about a 15 yr run so more than a few. Mac KW Freightliner all of them r void of this converter added board of protection we r discussing.
I quite electrcly ignorant so I'm still trying to wrap my brain around isolate power source from dedicated power.
What protection does that board and relays provide that a circuit breaker and possibly a diod would not?
Please enlighten me yoda sparky.
