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 |
Overview
All 1200 used a low-tone horn and a high-tone horn -- except STD which only came with the high horn.
H18 type was used in Coupe and GX Sedan H10 type was used by all other
26310-H1000 HORN-HIGH ALL 26310-H1800 HORN-HIGH Coupe, Sedan GX 26330-H1000 HORN-LOW Sedan DX 26330-H1800 HORN-LOW Coupe, Sedan GX
Location
The horn relay is bolted to the right strut tower, under the coil.
No. 3: horn relay
The high horn is bolted to the radiator Core Support panel.
The low horn is bolted to the right Hood Ledge just in front of the battery box in early cars. The bolt is used as the Body Ground Point.
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 hub. If this outer ring improperly lubricated. the horn can have intermittent problems. The Horn Button on the steering wheel connects this ring to ground/earth.
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 'H' wire)
* S - connector for Switch (in steering wheel)
The late relay can reportedly be used on early cars, but the wires are labeled differently. Wire colors are the same.
Late Relay 26321-G1600 7510-
* S - BG (wire Black/w Green stripe)
* R - ?
* IG - ?
