A few weeks ago, my lights started turning off. I'd come back later and they would work fine.
I thought it was the lighting column stalk, so I put in a temporary switch taking over from the stalk in providing an earth. However, they continued switching off.
Then, I happened to open the bonnet (at the front) and the headlights switched on (I'd left the light stalk in the on position). All the lights worked fine but when I closed the bonnet, the headlights' relay clicked the lights off again; I heard the distinctive click.
The under bonnet light switch seems to be the culprit as I the lights went off when I depressed the switch nipple, simulating a closed bonnet.
I'm not that good at automotive electronics and can't understand how a switch can cause the lighting relay to switch off.
Can anyone explain why this is happening?
