I have a Renalt Scenic that I have crash damaged repaired. I have rebuilt it, but can't get the ignition to come on. Auto data doesn't have a wiring diagram for me to work off. When I press the start button, a red reylay clicks on behind the dash, but all this works is the heaters, cigarette lighter, abs, stop lights and radio. Is there a start relay, or ignition relay, which needs activating.
