The headlamp control ecu is behind the switch, its all intergral, having checked the circuits and finding that they and the bulbs are good, I went back to the control, disassaembled the unit. main switch is a rheostat, checked resistance, and found that the switch was dirty, rotated the switch to clean the track, and reassembled. still not working, then had an idea !
Started the engine and tried again, bingo lights came on.
Also these cars have a light delay built in, if you turn ign off with lights on, they stay on for a short while, then turn off.
