[Healeys] Headlamp wiring

[Oudesluys]

Terry,
You can use the existing original wiring, headlight and dip switch to 
switch the relays, these primary circuits are very low current. The 
secundary circuit will switch the head lamps straight from the battery, 
starter relay or similar point with HD wiring. This secundary circuit 
will be additional and needs a much thicker gauge wire to keep the 
Voltage up and the heat down.
It is easiest to fit one relay for each dipped light and one relay for 
each main beam, so 4 in all.
As the original circuit now will only carry very low current, the 
Voltage will stay up, the heat down and also the load on the switches is 
very little thus saving them from burning out.
The fuse can be fitted anywhere in the wire between battery and relays
Fit the relays near the headlamps (if inside headlamp cowls, insulate 
well) for simplicity and looks, as you wil not have to cut the original 
harness.
You can of course use one relay for both dipped beams and one for both 
main beams, the relays can easily handle that, but than you have to 
modify the original wiring.
