At bottle shop at lunchtime and get back into the car to get back to work. Turn key and nothing.
Managed to start by attaching wire to starter exciter terminal and touching bolt at end of solenoid. So it's not the starter.
Thought it might be the ignition barrel as it has been loose since I bought the car a month ago. New barrel - same problem.
Manually turned knob inside column with barrel out. Same problem.
When I turn key or knob to start position brake light on dash illuminates.
