what would be proper wiring for your alternator if you are running stand alone and no stock harness? this car will be driven on the street so it needs a alt..

ive searched and all i found was that you have to run 12v to the alternator and person who said it worked for them told me in pm that he fried 2 alt before giving up and continued to run battery only..

any help would be great..

I wired mine up just like the factory had it and have not had any problems. What ems are you using?

thanks man that is how i wired it up today and while running i was getting 13.4-13.7v on my laptop from the alt power wire i was seeing around 14v so i guess its functioning.. im going to keep any eye on it and see how it goes.. im going to buy an actual guage for volts so i can see it when i dont have my software running..


i am running a dtafast E48 for now.. i also have a dtafast S60 which is newer and has a lot more features but for my all motor build the e48 is simple and works fine.. i like the dtafast sytems because i do not have a distributor..

What gauge wire do you have from the alt to the batt, I was also at 13.7~volts, when I upped the wire size from the alt to batt it went to 14.6~14.7v...

I'm not sure the exact size but it's prob a couple sizes larger than oem..

I was getting about 14v at the alternator at idle..

Anything 14V and higher is perfect at idle.
