Tracing the intermittent fault was the first priority and with the console removed I soon found that moving the wiring about caused the fault to come and go. The problem was to narrow it down to which wires. Trial and error revealed it was in the two standard connectors just below the heater that supply live and earth to the radio. Attempts at cleaning the connectors didn't work so I ended up replacing them with modern crimp connections. Not as neat but the fault was fixed. Looking at the old connectors I took off revealed some corrosion in the wires so they obviously got wet at sometime in the past - maybe from a heater leak judging by the location.
