head light wiring

[360rangie]

Does anyone have a wiring diagram for a 1986 RR. My headlight high and low beam have died, no blown fuses and can't check relays, I dont know which one is the h/l relay. FYI still have parkers.

There are no relays, there are fuses for high beam and fuses for low beam but if you have neither then either the light switch (most likely) or the dip switch (usually High beam goes first) are O.O.O.

Thanx heaps, I've checked the light switch and that seems to be working fine, (power in and out, parker, low and hi) might try the dip switch.

Does it matter that I can flash high beam with the d/s or is that on a diff circuit?

Forgive me for my ignorance, but what is O.O.O.

Out Of Order.
The high beam flash should be a seperate cct to the main supply from the light switch. If you are getting power from the light switch but not into the dip switch then the fault is between them, maybe a wiring connector is dirty or melted.

FOUND IT!
There was a break in the wire between the light switch (powering the low beam) and the fuse. I Just run another wire.

The HI beam drama was loose rivets in the HI beam switch, sorted by repunching the rivets.

Thanks much for your help

Might be a good time to make a new loom with relays with power straight off the battery.

You took the words right out of my mouth. Just finished wiring up the lights this morning. Thinking of using the current wiring to the headlights as a switching wire and have a separate relay for each light. Maybe even with those fang dangled HID set ups.

I know a few mates who have wired their main line powering the lights from the alternator, mind you its 120 amp jobby. Does anyone know what would be the pros and cons of direct off alt or from batt? which is better and why?

Noticed on ebay there a seller who sells pre made spotlight/headlight relay setups for around the $10 - $15 mark. There about 4 metres long all up. So plenty of length to get around the engine bay and up under the dash if need be.

Im running 90w/130s with hella 30 amp relays. I picked up off the back of the alternator purely because it was more convenient. Even with standard globes, running relays makes a huge difference to amount of light u get.

My 93 rrc was down to 10.5 volts at the light with the factory setup, it now has between 12.7 and 13.5 depending on alternator rpm.

Good relays are easily available cheap eg., off a VB Commodore there's a set of three on the passenger side inner guard that do beautifullly for headlight relays fon a Disco/Rangie etc. They are 30 amp and are conveniently plugged into a mounting block that can be used as one, two or three relay units.

You can also buy a 30A spade fuse block to suit, cost 12 dollars from Bursons/Repco. Just insert the relays in the wiring that leads to light units. The third relay can be used for spotties. Wire direct from battery to the spade unit and on to the relay. Takes all the load off the switches.
