Matter I: Can any one direct me to a photo or diagram of the MkII Spitfire main lighting switch? I have any old one that has two detents- the first turns on panel lights the second "arms" the headlights, I think.
Matter II: Any photo of the Spitfire MkII horn relay. There are four blade connectors and three wires- purple, purple with black tracer, and purple with yellow tracer. It was1997 when I thook this stuff apart and I neglected to take pictures. T.T.
 
HI Trevor, Don't know about the switch. However,The purple wire for the horn relay coil is always hot.It usually goes directly to a fuse. The Purple/black wire is the other end of the coil's circuit and should end up at the horn button. The remaining wire purple/yellow should be relay switched power to the horn. There may be a jumper missing here--Fwiw---Keoke

I will try to dig around and see if I can once again locate my US version, Spitfire 4 Owners Manual. That is the ONLY piece of factory literature I've ever seen with a CORRECT wiring diagram for the US market lighting setup.

You are essentially correct: the column switch is off /side /head (you DO have a dimmer switch on the floor, correct?) on a US-spec. Spitfire. The dash switch controls ONLY panel lights on these cars and only gets power when the column switch is at either "side" or "head" position.

I'd happily point you to my US-spec Herald wiring diagram (similar situation), but I recall that the Spitfire has a "flash to pass" feature as well. If so, that wiring diagram probably still would apply, but the additional wire your switch likely has (blue w/white?) would patch into the high-beam wiring circuit (same color).

Anyway, see Wiring Diagrams; meanwhile, I'll look around @ home for my Spitfire manual. (The Factory Workshop Manuals are NO HELP here! /ubbthreads/images/graemlins/confused.gif)
 
Thanks... Just after I posted the above, I looked in my wife's MkII owners manual and there was the horn relay question answered and may be the light switch. The car was made in Belgium- my guess is for the European market, the speedometer is kilometers and there is no high/low headlight footswitch. So, now I have to locate a short maybe on the white wires that lead to the fuses and the green wire powering the wiper motor, heater blower, and dash lights, I think. Thanks again. T.T.
 
Sounds like an interesting car! How did it get to AZ: bought and brought over by a serviceman, perhaps?

Anyway, if it is a fairly typical European spec. car, then the column switch should be side / main / dip headlamps, and the dash panel switch should be two positions: 1 pull for "master lighting" on and 2 for instrument lights. If so, then any workshop manual diagram should help you figure it out. If you need info from same, I have a factory workshop manual as well and can look up the connections. But I'll assume that the wiring diagram in that owner's manual MIGHT help, unless it was a US manual! Either way, the horn relay connections should be the same, I think.
 
The horn relay is solved from the MkII owner's book. It indentifies blade terminals that the Haynes does not. The master lighting switch- from the same book may be solved. Turns out the fuse blowing was caused by the windscreen wiper posts being unlubricated. We took the under dash gear apart and the motor ran well enough. One of the posts was spinnning freely but the other was very tight. I had another posts in stock- a parts car and tomorrow everything should go back together without electrical problems- at least on that circuit.
That's my guess that a service man or woman brought from Europe. Years ago there were two airbases in the Phoenix area- Luke and Williams plus the installations around Yuma. The car was complete. Some one had repalced the 1147 engine with a 1500 and replaced the original radiator. We added a single rail transmission with overdrive and rebuilt the engine using the high compression pistons, header, European HS4 SUs with the proper manifold and added electronic ignition. The plan is to drive the car in about two weeks. T.T.
