Derek,
I understand the idea of putting in what is basically a separate power feed for the brighter bulbs, but am unsure of the following details...
a) what type of relay to use or rating
b) where the battery earth point is / how do you find it
c) where the headlight ground is / how do you find it
Do you have any schematics you could either post on the site, or email me ?
Thanks in advance....  |
No Problem Ugly.
a) The relays are general purpose switching relays, available at any car accessory shop - cost about £2.50 each.
b) The battery earth point is the black cable from the -ve battery post where it attaches to the frame at the L/H side of the airbox.
c) The headlight ground is the black wire from the headlight bulb connector. Replace this with a heavy duty one to the above mentioned battery earth point. You could take it straight to the battery -ve terminal but there's no real gain and that's just another wire to get in the way every time you remove or refit the battery.
I used 4mm2 loudspeaker cable for both the ground and supply wires. It is very flexible and carry a very large current, far more tha than the headlight needs.
I have a modified wiring diagram at home showing the relay fitment, I'll try to remember to post it on the site tonight.
