It is really pretty easy to do. Are you in the San Diego area? Wiring is what I do and I would be willing to help you wire or just give you some advise. Please feel free to ask all the questions you like stupid or not. Later.
Hi, I also want to do the wiring in my bug and want to take all unnecessary from it, i have never done it before but i want to do it my self and the best way possible. so my question will be what is the best gauge of the wire 10 , 12, 14?
I'm in Tijuana so i can go and visit any of you in San Diego, if you are intresred in teach some triks..
These are Maximum amperages for a 12v system. When operating at 13.6v your equivalent amperage is actually more energy than the same amperage at 12v. I always run at least 1 size larger than needed based on tables like these. and always run a 10 gauge for the alternator. Pretty much everything on a class 11 except probably auxiliary lights are going to be around 16 gauge.... ignition, oil cooler, pumpers, radio all take more juice.
Electric ignition, fuel pump, gps, intercom, warning lights, take very little power.
Remember that when you're running things on the same circuit you have to add up the amperage.
Great info Brenner.
One other thing you migth give it a try, is to have cable thats used for RV wiring, the cable its a bunch of wire 12 + in one pice, this looks really good, eliminated the possibility of breaking cables, easier to install, etc. We purshase some in El cajon in a RV dealer and it works great. Instead of running a bunch of cable from the front to the back and used those plastic cover, this looks much better, plus it comes in gages that can suppport the amperage.
I am going to run two sets of shielded trailer wire cables from under the hood to the rear of the car. A 4 wire, 14 gauge cable to the rear compartment, and a 7 wire (1-8 gauge, 2-10 gauge, and 4-12 gauge) to the engine compartment.
8 - power to the fuseboxes
10 - alt
10 - starter
12 - coil (switch the alt wire to the 12 gauge wire??)
12 - oil press
12 - Brake lights
12 - Running lights??
The alt lead is the exciter, the one that goes through the ALT light. The big wire from the battery to the alt would be well, bigger. Starter is the same, It'll be a big wire to the battery, and a smaller wire to the solenoid itself.
The fan and pumper have really small wires coming off of their motors.. I know the length matters, but hopefully the 14 gauge will be acceptable. The fan is not large on either one.
IS 8 gauge big enough to run to the ignition and fuse box?
