What kind of wiring does a Datsun 1200 use?
Datsun 1200 doesn’t use a headlight relay, instead full power goes through the lighting switch and the dash harness. But a serious peformance issue is that the main wiring goes through a 20-gauge Fusible Link . Headlights want a 14 gauge wire for the full voltage to reach the lights.
Where does the wiring go on a Datsun headlight?
From here — depending on the position of the Dimmer lever position — it goes to either the low (DIM) beam of the headlights or the high (MAIN) beam of the headlights. The headlights are grounded via the main wiring harness. Completing the headlight features is the “High Beam” light in the instrument panel.
How do you test a car relay with no power?
If there is no power, the electrical system must be tested starting with the fuse then the relay. If power is present use the test light connected to battery power to check the ground circuit. if these tests check out, the accessory is bad and needs to be replaced.
When to test a radiator cooling fan relay?
If no power is observed at either 87 or 30, the fusible link or maxi fuse has shorted. Example: Testing the radiator cooling fan relay, the cooling fan should be operating. Step 14 – When replacing a relay be sure to match up the terminal location from the old relay to to the new unit.
Are there any fuses or relays in the engine bay?
I should also add that while checking the standard fuses and the 1 relay I was able to find in the engine bay, are there any other fuses or relays to check, which could be shared w/ other accessories?
What are the numbers on the fuel pump relay?
A high current circuit. This circuit can be identified by the wires labeled with the numbers 3 and 4. This is the circuit that delivers the voltage (and thus current) to the fuel injection computer (EEC Electronic Control Assembly), fuel injectors, fuel pump relay, etc.
How to check / verify a / C problems Nissan club?
1. Checked the AC relay in the engine bay – going to swap it with another relay of the same type to rule that out. 2. Checked that the fan works on all 4 speeds 3.
What happens when the relay is not activated?
When the relay is not activated, this circuit is ‘open’, and as such, does not send any power to anything. Both of these circuits are completely independent from one another, since the voltage/current flowing thru’ them don’t mix. To get into more specifics, this is what happens when you turn On the Key and crank the engine:
