I have a shunt between the + battery pole and the inverter, I hook up a digital multi-meter set at 10a. I measure battery voltage before a run with a digital meter. I’ll call the two lines out of the inverter line a and line b. I hook up a meter to lines A and B for voltage; this is 120v ac from the inverter. I put a clamp meter on line A or B, always about the same.
On the alternator side I have lines 1 and 2 from the motor, I can measure voltage there or anywhere across my cap bank, always about the same. I put a clamp meter on ether line or down the row of caps, always about the same.
Line 1---- ---- ----- ---- -----
cap cap cap Bulb Bulb (light bulbs are 100w, 120v)
Line 2----- ---- ---- ----- -----
Where I have the bulb is actually two bulbs wired parallel for a total of 4 bulbs. I put the meter for voltage on any cap switched on or where the bulbs hook onto the caps. I use a clamp meter anywhere along as it is about the same.
Again I am using a 10hp, 1725rpm, 3 phase junkyard motor, wired for 480v as PM. For alternator I am using an old 120v single phase 1/3hp 1725rpm motor wired for 120v. They are mechanically linked with a belt, the alternator is slightly over driven.
I have wired the alternator for 230v and have had a VxA of over 4000, no load other then caps.
Interesting is I have a higher voltage and amps between lines 2 and 3 on the PM then I do coming out of the inverter. I am going to build some sort of bedini extraction devise to see if I can charge a battery with the extra voltage.
