Hi. I have a bailey swift 490xl. I recently had a bulb go on the left cluster. Replaced bulb and now I have no power to the cluster at all. What is strange, I have power to the right. Checked the fuses, all ok. Replaced the connectors to the cluster on the left. Checked power from car. All good. The car is a 7 pin. And the van is a 12n. Have a connector. Any idea,s pls.
