I tried fitting after market projectors yesterday. When they were plugged in the was light ad mains did not work only sides and the 30% power on the headlight that these have.
So I have test with a multimeter at the head light multiplying and I'm getting just under 12v
All the fuses are ok too, and relays are clicking when they should.
Now to try and see it's a bad earth I rigged up some test wire, first just to test I put a straight live and earth from the battery to the bulb and it lit up brightly! Lol. So it be. Put the live pin on the bulb into the live connector on the multi plug and attached my direct earth to the earth pin on the bulb hoping it would work brightly, however it didn't??! It just did the same dull light.
So I'm at my wits end I don't understand why it's doing that if it has a direct earth to the battery and is plugged in to the
live of the multiplug which is getting just under 12v
My car is in bits as am I lol
