How Big Should the Negative Ground Be
I had posted a previous problem about my hard starting 427. I've deducted it is a negative ground problem thanks to your input. My positive cable is 1 guage. How about the ground. I have a 4 guage wire I'm going to ground to my scattershield. Is that big enough or should I go bigger.
Thanks, Ron |
Ground Wire
The smaller wire will act as a choke (restriction) and become VERY
hot. Use the same cable size ie: 1 or 0, as the amp draw with the standard starter is quite high. Consider one of the mini-starters offered by one of several manufacturers. They draw considerebly less current, weigh less and are more powerfull and are smaller. Can't lose. Rick |
Negative Ground
Rick-
Thanks for your input. I will use the 0-1 guage. I am already using a mini starter. Thanks. |
Electricity should be thought of as a circle.If it comes from the battery it has to return. Anything and everything in the circuit has an effect.The smaller cable on the return,ground,has a limiting effect. you can tell if the smaller cable is a problem by the heat and magnitic feild created when in use. The cables should all be cool.The starter also has a limiting factor, making it work. If the current didn't do any work ,resistance, you'd have a big surge and end up in a melt down.The bigger the cable the less resistance.If you use the same size neg as pos and they are ample size the starter and battery become the limiting factors. If you were to keep upsizing the cables eventually you will see less and less of a gain. Point of deminishing returns.
