[QUOTE="jondle, post: 756545, member: 2598"] I think you should focus on the problem first, before looking for the solution. By that I mean, you don't really know what you need to implement yet, just some speculation. First things first, test, test, test. You need to figure out what is going into the diff. Then you need to know what each of the wires does over time. There are probably two wires, a hot and ground. Measure the volts and amps going across them in all situations you can think of. Try to correlated the voltage drop to an event; the event could be a certain amount of time or when the diff is actually locked or something I'm not thinking of. Once you have that information, you then know what problem you are trying to solve. Your problem would be something like, "I need 13V with 5A for 30 seconds and then 5V with 5A continuous." Plenty of people on here can help with the electronics once they know what you actually need. There are many ways to drop voltage. You probably want something that is more of a regulator than simple diodes or resistors would be. Remember, 12V is a rough estimate for automotive voltage and it normally is between 13 and 14 with the car running and closer to 11 when it isn't. Again though, the actual electronic components don't need to come into play until we know what we want the electronics to do. [/QUOTE]
