Now when you Pv Cable are installing multiple car amps in you system the procedure is somewhat pertaining to. You have the main fuse within 12" belonging to the battery. The rating of that particular fuse are going to determined by all the fuse ratings of all of the amps you are installing. So let's say I added another amp to the system above that also amp had 3) 20A fuses. So that would give to us a total of 60 amperes for the amp as well as the 25 amperes for the opposite amp to obtain total of 85. I'd want my fuse along with battery for 85, or most likely rounded up to a 90A join. Now I also need to fuse each amp as well. For this you would use a distribution section. A distribution block is just what it sounds like; it distributes the particular Power wire to smaller Overhead power line wire which go to the person components.
Before you start to that offer regulator, pull the circuit fuse to make sure the motor won't start when you least expect it.
