This is really weird, everytime i test the circuit i get a different test reading on the volt meter,i just put a link between the 3rd rectifier down and the + bus bar and then tested all the readings on them and it seemed to be correct as i went to through them the voltages went up to 34v at the top 1, i took it off and then tried it again to double and i just wasnt the same, i tried again quite a few times but still i didnt get that test result again, is there a link missing from your diagram, or do you thunk i have a faulty component somewhere, there is nothing loose i have checked everywhere, i want to ask, if i was to start again ,is there any way i can check and test it as i go along whilst putting each component in place, if so then please tell me what is the procedure.
