Strange O2 sensor readings

Hi All,

Wondered if anyone could be of assistance. Trying to work out some possibly strange behavior with my O2 sensor readings on my 87 turbo 16v.
When idling, no fans cycling, no headlamps on I get an O2 voltage cycle between 0.8v and around 0.2v. As soon as the fans come on or the side or headlights are turned on the reading drops to 0.03v and stays there until the electrical load is taken away. (Headlights off or fans turn off).
I'm a little stumped by this. The reading suggests a lean situation, anyone know what could be causing it?
