1993 Dodge Caravan hoodopener

Since there is pros and cons for both system its good to have both then I guess. But I just got my dodge, and its been standing outside for 2 years before I bought it with the unavoidable corosjon on electrical equipment. Now after a few months of use, only the computer in the ceilingconsole inside does not always work.(The one that show fuelconsumption pr mile and some other optional infoes)i need to know where its connected?I meen what relay or fuse supply its current, and where its located on my 93 model

My alternator had worned down brushes, and altso a fracture between the threaded poles sticking out and the brushes themselfs. In norway I cant get that plastic part containing those brushes, only the whole generator wich cost more then I paid for the car. For now I broke the sides of the plasticholder, fitted new brushes, and softwelded cables directly from the brushes wires and then led them all the way around and out, connecting them directly to the cablegrid in the enginecompartment. Altso had to make plasticlids to prevent then brushsprings from popping them out sideways. It works, but I wonder if the part can be ordered from the states?And costs of it if?
