## Questions & Answers

**Q: purchased in March and drove car car twice. Stopped working. What is next step**
A: They have a 30 day return policy and we are past that

**Q: will this work with 3 wire systems ?**
A: Yes it will work with a 3 or a 1. The people on here saying it won't work as a 1 wire are ignorant to 12v automobile charging systems!!! They think they know but they don't! It works with 1 wire or 3 if you know how to correctly excite it. You may have to hit it with 12volts for a few seconds to build residual magnetism in the stator. If you don't know what I'm talking about then I suggest you study up before installing this alternator. Self excited still may need to be manually excited for the 1st time. Then depending on how much amp draw and load you may need to find tune the output or you'll be the guy saying " worked great for a couple of months then burned up". There is a lot more to it than most people understand.

**Q: Does this work with air conditioner?**
A: Yes

**Q: What are the connections label r and f for**
A: Supposed to be 1 wire connection, battery + to red bat. post on alternator.  I didn't use the spade terminals. Can't explain terminal R. Normal markings B, battery, A, armature, F, field.

Everything is as very wonderful, put it in a 1967 Chevy nova, looked amazing. The specs in the alternator was right on. Worth every bit of it and more

### ⭐⭐⭐⭐⭐ poor quality
*by T***M on December 10, 2025*

alternator does not put out enough voltage to the battery to keep it charged as well as run the car. I have done multiple tests on it after the vehicle stuck me off the side of the road. So buyer beware. It worked for about a month but past my return period. Now I am out.
