Roof light wiring diagram - Please examine: most of the wiring diagrams posted on this page are scans of original ford diagrams, not aftermarket reproductions. These have been scanned and published as very big files, to hold their readability. The 1969 diagrams and all others marked with a crimson asterisk (*) were despatched to via 1ec5f5ec77c51a968271b2ca9862907d from various assets, so their first-class and/or size might not be as precise or as certain, however i nevertheless gratefully well known folks that took the time to ahead them for posting. Eventually all diagrams posted right here will be hello-decision for simpler reading. Lighting fixtures managed by using forestall lamp transfer and flip sign indicator f100 via f350 vehicles are ready with a mechanical plunger prevent lamp switch that's established on the brake pedal arm. This transfer is designed for maximum loads generally much less than the fuses or circuit breaker within the circuit, however enough for everyday stop lamp hundreds. The maximum load is 12.Five amps and under no circumstances are masses in excess of this fee permissible.
If the total load on both headlamp circuit breaker exceeds the breaker score, the headlamps or taillamps will cycle on and stale indicating the overload. If this happens, a part of the introduced lights ought to be stressed out via a relay, feeding the relay coil from the headlamp switch. The feed from added lighting to be controlled by using the headlamp transfer must be terminated in a male bullet connector and be related to the girl bullet take-out (brown wire -- 285 circuit) on the left-hand aspect of the instrument panel harness (close to the emergency brake). If the car has roof marker lights, this bullet will be occupied with the aid of the feed from the roof wires. In this case fabricate a "y" jumper to permit each connections to the single connector.
1) the headlamp switches on all 1970 ford vans (besides "w" fashions) hire two fundamental circuit breakers, one 12-amp for the headlight circuit and one 15-amp for auxiliary circuits. Connections to any factor within the circuits controlled by the headlamp switch will be on the auxiliary circuit breaker, except connections to the #12 circuit (headlamp hello-beam, green twine/black stripe), the #13 circuit (headlamp low-beam, crimson wire/black stripe) and the #15 circuit (feed twine to the the dimmer switch, crimson twine/yellow stripe. Connections to the 12-13 or 15 circuits (headlamp bulb circuits) ought to be averted.
