We are trying to re-wire a my uncle's Challneger with a Painless kit. I tore out the plastic box that was built into the fire wall, and had the original guages re-built. The problem is the hot stroker that is being built has an alternator that runs 140 amps (single wire) and we need to not have the entire load run through the anmeter guage. Mopar Action said that we can run the another wire parallel from the alternator to the starter cut the amps. At best this is only going to cut the amps down in half (in wiring theory). I've heard their was a kit that could do this? I really hope to be able to finish this wiring project on Monday. Thanks for the inputs. |

If the bypass is made of heavier wire (try 6 AWG) it will have lower resistance and carry more of the current. This is going to sound harsh, but don't you keep claiming your household is made up of engineers? No one at home understands Ohm's Law? |

yeah,a bit harsh Josh,particularly when they are trying to measure amps with an "anmeter". gotta get the right tool for the job.  regards,Rod

Don't let the kidding-around get you down; "Painless Wiring" makes a catchy tradename, but as far as truth in advertising goes, it's a little...um...lacking. Could be worse, though, if they'd marketed it as "Super Quality Wiring".  It can be made to work. And yeah, 6shotvanner's got a point...remember, mechanical engineers build weapons, and civil engineers build targets.

Well, my uncle is a graduated Construction Engineering Management. My father is a police officer who wants me to graduate from college since he wasn't able to go. I'm studying to be an Civil Engineer... so how are we a household of engineer's? Is there a quote from me somewhere???? I've studied Electircity in relation to physics, Ohm's law is child's play next to Kirchoff's law and Bio-savart. So.... have fun with that. Painless isn't bad we bought a brand that is American made, and comes with thicker wires. The kit isn't bad for what I used it for was to replace the OEM harness that kept springing up shorts. We are messing with the car, wiring, electronics so much that it isn't near stock. Would like to know more options if people have any. |

yep. " Is there a quote from me somewhere???? " Jan 9th thread re prices for roller rockers. see below: " I'm an engineering student, in a house of other engineers, and we've been ...." so Joshie you are vindicated. runsvs - hope your project all works out,I mean no harm,just being picky. I will butt out now.  regards,Rod

Oh! The house full of engineers as in the house I live in Corvallis where I go to school at OSU and live with 5 other guys, 4 of which are studying engineering. I understand where it comes from now... I thought they made a kit that could roughly do what I was talking about cause of newer v8 engines. I guess I'll keep looking. |

Got to love that Kirchhoff. As a CE student, you should have gotten the subliminal message from the EE prof. that your branch of engineering dose not cope well with electrons. Don't feel bad it is normal. Kirchhoff, Wheatstone, Coulomb, Faraday, et. el. were put on this third rock from the sun just to confound CE students, never mind that chemistry black magic crap... It has been many moons since I have had to think about any of this electrical stuff, and I may be experiencing a bad sector or major brain fart here. So someone please feel free to correct the following miscellaneous ramblings if I have misguided the lad. I belive that the flow of electrons, juice... what ever someone here advised me won't fill my trunk, will follow the path to the load proportionally to the size of the load. I refer you to your old buddy Kirchhoff's treatment of parallel loads or resistances with respect to current. Remember the voltage is limited to 12 or so volts dc, and your loads have a given resistance so the amperage will be controlled by these constants. I = E/R Unless you have some killer stereo, nematic contraption operating the suspension, neon lights, air conditioning, or rear window defoger, most likely the full 140 amp output will not be utilized. In other words, the 140 amp rating of your alternator is a peak output for that device. If you do run a conductor over to the starter relay be sure to size it the same as the conductor going to the amp gage. likely it would be a #12 or #14 gage. |

Why?

The harness people came up with this idea. I probably wouldn't bother if the car is mostly stock in its electrical current requirements.

Because someone said so. Great. If we ignore the resistance of the bulkhead connector and ammeter itself another 12 AWG wire (assuming stock is 12 AWG) would carry the same amount of current as the existing wiring. Potentially that's 70 amps and too much for any 12 AWG wire. |

Yeah, Kirchoff and Faraday really wrote all those papers just to piss of the CE students that would trickle down through the years. Actually I enjoyed my Physics series despite the late nights. The sum of the project was a success and what we ended up doing was building a shunt which I can find the webpage which told us how to do that in the near future. The biggest problem was the engine wasn't finished yet, the A/C kit was kinda flimsy, and the electirc fans could probably push the car if we mounted it on the bumper. I will repost with a more techincal finish soon. Thanks for all input and ideas! |
