The Murena indicators come off a live circuit not an ignition one like most cars.  The radio is also fed from a live circuit, so it seems you have either disturbed a live circuit, have blown or a bad live circuit fuse, or you have a bad connection in the live circuit somewhere.

Circuit 3 is the live to the flasher relay.  Circuit 70 is the output to both the hazard and column switches, 70A and 70B feed the warning lights in the instrument panel.  The column switch feeds either 72 or 73 (right or left) for indicators or the hazard switch feeds both for hazard flashing.
