[QUOTE="JimGore, post: 1084018, member: 3"] Check the voltage at these points and let us know what you see: 1. After the transformer secondary (AC), 2. After the rectifiers (DC), 3. If any kind of regulation is done, then check after the regulator circuit Do all 3 tests with the load connected (A), and then with the load disconnected (B). So I want to see those voltages like this: A1: A2: A3: B1: B2: B3: Kind regards, Ian. [/QUOTE]
