I just bought the 1 wire power master alt. for the race car. Im assumming the one wire I run goes all the way back to the off / on switch so when you turn the switch off the car kills. My question is "What guage does that wire have to be and does it go all the way to the off/on switch" ? Any options on this ?
I noticed the coronet has the two wire factory mopar alt. 1- field and 1-power. Both wires are not that large at all and have avg. size terminals on them. Why does the one wire power master directions suggest I run 2 gauge all the way back ? I have 20' of one guage cable but that seems like overkill doesn't it ? Any ideas greatly appreciated.
Bring the alternator directly to the battery, unless you have a 4-post cutoff switch with a post dedicated to the alternator. If so, make sure the switch has large lugs and is rated to handle the current generated by the alternator, like the Cole Hersee 75912. That is probably the best and cleanest way to go.
If you go directly to the battery you will be fine, but it wouldn't be a bad idea to keep the alternator from being hot all the time by putting one of these relays between the alternator and battery so that you can sever that connection by turning off the main power. http://www.jegs.com/i/Painless/764/50105/10002/-1
Perhaps our resident electronics guru could hook you up with a cheaper "unbranded" continuous duty relay that will handle the job.
