Every now and then, when I either indicate, turn the heater fan on or flash the headlights on my Mini - the radio goes off ? I've no idea what is causing this - any suggestions would be much appreciated.

Look to see if all of those items use the same main fuse. Take some time and clean all your main fuses and most of all fuse holder clips. Then check all your wire end connectors (spade) on the fuse block.
Did you put the radio in or was it done in a shop?

Thanks 'notamini' for your reply. I did replace the radio with an identical Rover unit when the old one stopped working and had it fitted at a audio shop. This was done some time ago, and the problem has only recently started to happen. I'll check the main fuses and clean up as you have suggested - Many thanks again.

From memory heater and indicators are on the same fuse (ign switched live), but not the headlamps - Though I might be wrong about mid 80s onward Minis. Check the battery connectios as well (and the one from battery to starter solenoid, as that carries the main live to the rest of the system). My stereo has developed a habit of glitching off when I flash the headlights, but it turned out my earth lead had come loose (on the Metro). Tightened it, and so far things are behaving properly again. Which is handy when you want to remind idiots pulling out on you, and then dawdling, that you happened to have right of way... |

You're right in that.
It has been said the biggest electrical problems in a BMC are due to poor grounding. Anything that carries heavy current at any time should be monitored for corrosion and tight hardware.
I can see where your 'alternate' grounding circuits would try to take up the slack when a major 'artery' has been weakened. Smaller wires have higher resistance. Higher resistance results in lower current. Trying to force higher current thru results in loss of voltage. Today's radios do not always turn themselves back on when power is lost.
