Datsun 1200 used dual horns (Japan STD models used a single horn). The horn system uses a three-connector relay, which is bolted to the right-side strut tower just below the ignition coil.
Contents[hide] |
Location
The horn relay is bolted to the right strut tower, under the coil.
The horn(s) are bolted to the radiator Core Support panel.
No. 3: horn relay
Horn Button
The horn contact is part of the turn signal switch. If this tab is bent, or electrically burned, the horn won't work. Ditto if the T/S switch is loose.
The horn contact touches the underside of the Steering wheel. If this outer ring improperly lubricated. the horn can have intermittent problems.
Wiring
Horn wiring schematic:
- Fuse 'H' is in the Fuse Box
- + battery voltage is supplied by the horn relay. The horn button switch earths the relay, causing it in turn to supply voltage to the horn. As the horn is a high amperage device, this keeps the power wires out of the steering wheel
- Earth (ground) for the horn is just the fact that it's bolted to the core support panel
- Earth for the horn button goes through the steering wheel hub, which is bolted to the steering gearbox shaft, so it is earthed via the metal of the steering column/gearbox.
Relay Wire Colors
* Green: to horns * Green/white: to 15A fuse in fuse box, Battery side * Black/green: to steering column connector (for horn button) * Case bolts to body (earth/ground)
Early Relay
Stamped on the relay case are:
* H - connector for Horns
* B - connector for Battery (through fuse box)
* S - connector for Switch (in steering wheel)
Late Relay 26321-G1600 7510-
