If I install an external regulator, I will be able to charge the batteries but will it also enegize my engine control sensors?

 

i have a question...i have a flip switch hooked up to my fuel selenoid. i accidently left it turned on and i lost my charging system and all gauges... i manually pulled up the fuel selenoid and drove the truck none of the gauges are working nor the charging system and my flip switches for tc lock up and overdrive flip switch do not work... Does this sound like i blew my computer??? my cps sensor is brand new from cummins 2 months ago... remember that i accidently left power going to the fuel selenoid and once it shorted out everything stopped working

 

Start simple check all fuses and relays, then trace wires to make sure they are still good. Far as a computer there is no ECM on a 12v there is PCM tho.
