I have tested R1 with ohm meter and get 0 to 954 ohms from low to high on adjustment no jumping around as I adjust it was smooth. Volt reg board I bought a certified one to replace the one I had for which now I think is good also. I had a electronics buddy test items on board of old one and he thinks is good and I get same values on new board. Because I know the old one give me correct voltage how it was adjusted I did not play with that board. I forget now without looking at the diagram but the two adjustable resistors on the volt reg board I wrote down the ohm readings before I adjusted them so I could get back to original. Nothing that I change on those two resistors or R1 has any affect on voltage output so I am thinking something else before or after volt reg board might have me. Just for kicks and giggles I was going to check T1 and T2 however not tonight. Wife’s car was hit with a falling high voltage line about 1 mile from house because beside her someone took a pole out and line caught her mirror wrapped around car and axel. She is not hurt, car did not fare as well. Anyhow that knocked my power out at the house so we are in the camper currently, clamping in the front yard. Thanks for your time, any other ideas to try or which direction to check?
