MG Car Repair: 1977 mgb no power in ignition circuit, test light, road map

Question
I have traced the circuit.  The battery is good.  the relays test out.  there is no power anywhere in the circuit.  Can you help?

Answer
John, "Tracing a circuit" is done with a 12v test light. You need a wiring diagram and a test light to trace the ignition circuit. I always start at the load (the ignition) and trace back toward the source (the battery) If you do that, you can not fail to find where the power ends since you know the battery is good. Only check (with the test light) only one joint (connection) at a time. The diagram is like a road map. If you don't have a diagram let me know and I will post one on my web site for you to copy.
