Dave,I stand corrected;The blue and white wire connect to the main or high beam and the red /white is the dip or low beam.They connect to the 87 terminal on their respective relay.Sorry 'bout that; Was half asleep last night.

Larry

Dave,If you have a bad ground somewhere in the system the current will find it's way through other lights, gauges or anything that is grounded.The black wire is the chassis ground wire in all cases of the original wiring.The blue with white wire should connect terminal 87 on the low beam relay to the low beam terminal on each light.The red with white wire should connect terminal 87 on the high beam relay to the high beam terminal on each light.The black wire needs to connect to a GOOD ground (for the H.L.'s do not use the Lucas type multi connectors)If possible, send me a diagram of the relay connections of all the headlight relays.

Larry

Larry, thanks.
 
  
 
This is a car I had converted to LHD, so my driver’s side is on the port side of the car.  Looking at the driver’s side headlight, there is a connection for the low beam (outside light) that has 1 black wire, two Siamese blue with white striped wires and two siamese blue with black (or maybe red) striped wires..  The passenger side has 1 black, 1 blue with white stripe and 1 blue with black/red stripe.  On the bonnet support pieces there are three what looks like relays on the driver’s side and two on the passenger side.  One on the passenger side looks like it was a replacement, it is much larger than the others. I can’t get close enough to see any markings on the black boxes.  The wires to the boxes come straight out of a wiring harness, so I haven’t traced the wires yet.  On of the black boxes on the driver’s side has some wires that are blue with various colored stripes.  At the firewall there is a yellow box that looks like it was added on at some time, that has numbers on it that are 30, 85, 86, 87 which match the numbers on a wiring diagram I found on line that said it was for a headlight relay kit, but I can’t see behind the relay to see the wires coming into it.
 
  
 
Excuse my ignorance, but if a light works then it has both power and a ground, so how can working in the opposite direction be a ground issue?

Evening, Dave,
 
Wiring those high power lights into the INVENTOR OF DARKNESS electrical system requires some special wiring and really good ground connections. Can you determine if they were installed using relays for there control.
 
The system has defiantly got a ground problem.
 
I am not familiar with the 1991 model, so do not know if it uses the wiring system as the early models.
 
If you would look at the colours of the wire that connect to the lights and let me know, maybe I can help you.
Regards,
Larry

I’m settling in with my newly acquired 1991 Mantula.  I have an issue that is puzzling me.  A previous owner installed aftermarket HID low beam headlights.  I have not tried to drive at night yet, so I only recently tried to turn them on.  The first time, they flickered quite a bit, but came on.  Now the low beams don’t come on at all..  I asked Rory about it and he said that the engine needs to be running and my previous attempts were without the engine running.  Yesterday I started the car and turned on the lights.  As soon as I got the switch into the position to run on the “parking” lights, my tachometer stopped. When I turned the lights off, the tach started again.  Also with the lights on (mind you I haven’t even gotten to the position to turn on the low beams yet), the turn signals don’t work, but turn the lights off and everything works again.  Still even with the engine running, the low beams don’t work.  The high beams do work, but the little blue light on the dash which should indicate the high beams are on is actually working just the opposite.  The blue light is on when the high beams are off and the blue light is off when the high beams are on. Are there any electrical experts out there that might point me in the right direction?
 
 
 
Thanks,
 
Dave
