Manta again Posted October 19, 2011 Share Posted October 19, 2011 Ok the head lights don't come on with the switch and full beam won't stay on but hey the side lights work. All fuses seem intact. Any suggestions where to go next? Quote Link to comment Share on other sites More sharing options...
taylorblue5 Posted October 19, 2011 Share Posted October 19, 2011 I'd try the earth wires in the engine bay etc. Every Manta iv had has weird wiring, check the connections are clean against bare metal. Same for the relay next to the fusebox, its mostly just trial n error cant give a definitive answer as im not sure what the standard setup is as things r fixed n bodged over the years etc etc. Quote Link to comment Share on other sites More sharing options...
mantasrme Posted October 20, 2011 Share Posted October 20, 2011 If full beam works when you pull the indicator arm (to flash the lights) then the wiring, and bulb are ok Its possibly a faulty light switch in the dash. To check pull the headlight switch from the dash and get a voltmeter out. Find the power into the switch then turn to sidelights and find which other wire then has power. Then turn to dip and see if one of the remianing wires is then live, if not you have a dodgy switch. If you do get a wire that becomes live on dip the switch is working and the problem is further down the line. Follow that coloured wire to the next connection and see if there is still voltage. Continue doing this until the voltage disapears, whatever the thing is between having voltage in the wire and not having voltage is faulty Might be a connection/ relay/ fuse box etc etc I'd bet on the switch if your headlights work on flash, and if you need one and don't have a spare PM me your address and i'll send you one Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted October 20, 2011 Share Posted October 20, 2011 power from the headlight switch in position 2 goes to the dip/main stalk.check you have power going in .ive know these to have a broken lead ( one lead off will give no lights in position 2 but flash will work & sidelights will work ok).normal square headlamp types have no relays its all fed throu switches Quote Link to comment Share on other sites More sharing options...

dynamytedan Posted October 26, 2011 Share Posted October 26, 2011 isnt there a dimmer relay in the passeger kick panel that stops the lights from working full power with only ignition on ? ....its a rather big black box relay i think ....never seen one tho these go a bit faulty and stop it all working compleatly . just a simple unplug it ,bin it , and agro is no more .

Manta again Posted October 27, 2011 Author Share Posted October 27, 2011 I'm pleased to report that a new headlight switch resolved the problem. Thanks to all who replied and especially Dave for supplying the new switch. One problem solved more left to do. Quote Link to comment Share on other sites More sharing options...
