Hi, Here is one probably not too complicated but I am puzzled. Changed today the H1 dipped and main beam bulbs. Just followed the instructions in the Owners' Manual, because opening the covers varies from car to car. Well, a bit of a pain really, but managed. Checked the lights after the change, without the engine running. Now, what a surprise... Tried to start the engine, it coughs and makes a funny noise. Turning the key to mid point lights up the warning light test as usual, but when going to turn to start the engine, it makes a really "electrics not right" noise and the engine will cough but won't start. I haven't seen this before... Any ideas anyone?
