Disconecting a battery - how long?
Discussion
I have an issue with my headlights. Basically, selecting full beam only illuminates the dipped bulbs. So I have no full beam at all. Otherwise the lights do as expected.
I've been told that disconnecting the battery should reset the ECU and everything should go back to normal. I tried this at the weekend but it didn't make any difference. I only disconnected it for 2 or 3 minutes. I'm now thinking maybe I should have disconnected it for longer. Any ideas?
