Originally written by Broken Bit on 2006-12-23 9:50 AM My question is weather or not a diode should be put in the "hot" wire before it gets to the deep cycle bat. on the trailer so it will keep it from backfeeding to the truck. And if that is the case, what kind of diode should be used? And what the heck is a rectifier for? I was lookin' at some diodes on the Radio Shack website and seen where some diodes have a rectifier built in with it. I would recommend a "Diode" be installed. This site will answer a lot of your questions. It has a wiring diagram for multiple batteries. http://www.e-marine-inc.com/products/alternators/isolators.html A diode will act as a rectifier (which converts alternating current to direct current) by blocking the flow of current in one direction but allowing current to flow in the other direction. So a diode and rectifier basically perform the same function. |
