Current revision
Datsun 510 uses headlights that are always hot, but not connected to ground until the Lighting Switch is pulled.
Contents |
[edit]
510 Switched-Earth Wiring
Headlights are not permanently grounded as in newer Datsuns Headlights are permanently connected to HOT via the Fuse Box
Original 1968-1969 6-fuse fuse box One fuse powers both Headlights
1969-1973 Dual-Fuse Headlight Circuit]
New for 1969 8-fuse modular fuse box 'HL' 10A RL Power to Left Headlights 'HR' 10A R Power to Right Headlights
Relay switches ground on for either * High beams (all 4 lights) * Low beams (2 outer lights) Relay does not switch the 12V HOT side Relay switches the GROUND wires Relay Coil is powered by GL wire from Lighting Switch Relay Coil is switched by BR wire from Dimmer Switch * ungrounded = Low beams switched to Ground * grounded = High beams switched to Ground
Dimmer Switch * Only connects to Ground (High beam position) or disconnected * No 12V runs through it
Lighting Switch * controls headlights, park lights, dash illumination lights * does not control turn signals * does not control dash pilot lights (OIL, CHG, P.B)
Dash Illumination Lamps (2) are grounded though Pin 2 Black wire. GW Pin 1 goes to Lighting Switch
OIL pilot lamp is grounded via Oil Pressure switch G Pin 8 goes to 4-way Flasher Switch
CHG pilot lamp is grounded via Voltage Regulator G Pin 8 goes to 4-way Flasher Switch
Parking Brake pilot lamp is grounded via Handbrake switch G Pin 8 goes to 4-way Flasher Switch

Alternate Relays
You can use many different relays if you jump the wires from the harness to the relay pins. For example Nissan 25230-C9900 is only $2 at Pick-n-pull and used by hundreds of Nissan. Or $10 new at RockAuto.com.

Relay Repair
http://www.510coop.com/completed/HLrelay.htmCarefully pry the cover loose. there are four crimps, one on each side. uncrimp carefully with a screwdriver and remove the cover. Now between the contact on the bottom of the plastic piece is a screw. Remove it and carefully lift the guts away from the base and you should see rust on the bottom. Sand that clean apply so dielectric grease, reassemble and you should have a working relay. It's the rust and corrosion that is interrupting the circuit. Be careful of the wiring in the relay. The unit itself is pretty tough but some of those fine wires can break if you get too rough.
So, that's what I did...and now I have headlights! Thanks Bruce!
