Note that at first half video the voltage out of fwbr when looped is about 19.8VDC and battery voltage dropped to 11.93 However second half of video there is 22VDC from fwbr when looped while battery voltage does not drop and stays at 11.99VDC
Perhaps the trransformer has the backemf currents from rignt side secondary reinforcing the left side secondary (and vice versa) while bypassing up and over the primary core leg - as those shunt bars are supposed to do. (??) This would explain (somewhat) why voltage goes up to 22V from 16V when rectified secondaries are "loaded" from the connection to the 12V battery that is also running the invertor same time.... the secondaries are "reinforcing themselves" with the opposite secondary's backemf magnetic currents.and its the two secondary core-legs that "recieve" the extra magnetic currents, then this induces into the secondary windings to increase in voltage.
Doug, what is the voltage of the battery before you start, so nothing connected, no terminal no nothing. Than hook up all the stuff and disconnect after say 10min and chexk again the voltage. A second battery would be better clearly
Hi Hans It was 11.99 before anything hooked up, sorry I had no time not even 90 minutes yesterday but letting it charge or drain battery for 90 minutes good way to check if anything good is happening so will do that today I hope
Sorry no idea but maybe charge a second battery instead of the loop see how it performs. I thought you were supposed to measure current as close to the ground as possible in DC?

I fixed the invertor, it needed a MUR 160 diode replaced.

good idea to charge separate battery , also could measure currents at the ground of battery too
Thanks
