Carb and misc. other wiring, 73' 610 wagon


610StaWag

Recommended Posts

I noticed wiring coming from multi-wire connector box (near what looks like wiper motor) running along firewall. When it gets to behind the carb, two wires branch off (both are green with yellow stripes). These wires go to a plug/connector and then as one wire, goes to the clear cover box.

 

Here is the carb wiring  issue I am dealing with right now: There are three wires I am unsure of. #1) Green with two black stripes= this wire terminates in a slip plug fitting and then becomes a thinner plain green wire. this wire is cut and dangling. #2) Turquoise, no stripes. I have wired this to the fitting that I believe is a heated choke controller (?). #3) A thicker diameter light green wire. There is a non-original looking crimped on fitting that converts this single wire into two wires, one is red and the other looks like the thicker diameter light green wire. Both wire ends are dangling. Shouldn't the loose wires plug into something?

 

Below where the coil is, there is a green wire with two yellow stripes. There is a round plug-in connector at the end, but nothing is plugged into it. Should these plug into something?

 

Below the washer fluid bottle there are two loose wires not connected to anything. One is red and green striped. The other is black with a yellow stripe. Should these plug into something?

 

Behind the headlight (driver's side) are two loose wires, i.e., not connected to anything. One is red with a green stripe. The other is solid black.

 

I was told that our "Datsun 1800" (the emblems on the rear quarter panels) might have been a Canadian car. If it is any importance, the coil is wired: Negative= Black and Black w/red, Positive= Black w/green stripe, Black w/turquoise stripe.

 

There is a short with the lighting system, but I don't know if any of this relates to that.

Early 610s had the Datsun 1800 emblems. The '74 had an L20B so they were changed.

 

'a short in the lighting system'....  a short will blow fuses. Does it blow fuses or simply not work? This does not help much. What lights blow fuses or do not work? Parking lights, headlights Hi or Low beams??? Dash lights???

 

Cut wires? Or loose.. unplugged??? 5Red/Green stripe is likely the power to the high beam. Black is the ground for Hi and Low beams. See if the headlight is not plugged in.

 

 

Black/Yellow might be for the washer motor. Is the washer motor plugged in??? Should have Blue/Red and Black/Yellow wires.   The Red/Green might be for the left side fog lamps if equipped. 

 

 

Maybe post pictures of the carb and the coil wires.

Regarding the “…a short in the lighting system…”.I was just told by an auto electric guy that there was a short. But this is the same guy that, when he worked on another of my cars, said: “there were a lot of extra wires so I just cut them out….the wiring didn’t follow the wiring diagram so I re-did the wiring the way it should be done.” It took me a month to fix the “repairs”.

 

Car does not blow fuses, simply doesn’t work. On a very close visual exam, fuses look ok, but since the car is old, I will be removing all the old fuses, cleaning/checking contacts and installing all new fuses.

 

The car is in primer awaiting color coat painting so tail lights, sidemarkers and turn signal lights have been taken off.

 

Headlights: Low beams (outer most lights) work ok. When I use the steering column control to turn on the high-beam circuit, the blue indictor in the speedometer turns on and both headlights on the driver side turn on but on the other side, the high beam lights up but the low beam turns off.

 

Dash illumination does not work. The brake lights in back did not come on so I had made a jumper from the brake pedal’s switch to the rear brake lights (so I could drive the car on the street during daytime.

 

Radio does not turn on. Horn does not work. Rear window defogger dash indicator (blue) did illuminate when switch is turned on this morning, but now does not.

 

Turn signal dash indicator arrows do turn on (but do not flash on driver’s left, it does flash on the right, I guess because the lights have been removed).

 

No fog lamps installed on car.

 

Wiper motor is plug in, but nothing happens when I turn on the wiper controls. The washer fluid bottle has no wires plugged into it

There is a bare two prong plug on the bottom.

 

I will post photos (carb and coil).

 

I just noticed that, after the ignition key was turned on for awhile, the coil was too hot to hold.

Description for prior photos:

#2987 The Coil.

#2988 There are no wires plugged into the bottom of the washer fluid bottle (the connector are two male flat blades, what color should the wires be? Below the washer fluid bottle, note the two unconnected wires coming up from the lower right corner of the photo. Near the upper center of the photo is a unconnected red/green wire. A bit hard to see is another unconnected wire directly below. The loose broken fitting if this wire is over the left edge of the white plastic connector box.

#2990 Same as 2988, but at a different angle.

#2992 Connection to carb and a loose unconnected red/green wire.

#2994What is the cylindrical device attached to the side of the carb? It has two broken connectors, and nothing wired on. What wires are supposed to attach here? The device is loose and wobbles.

#2997 Side of carb, should the second vacuum port have that cap on it or is there a hose that is supposed to be connected here?

 

I am sorry that I have been unable to learn how to properly use the photo programs, PhotoBucket, Flickr, DropBox, etc. I have read the numerous posts (going back to 2009), but I still have not figured it out. I know Datzenmike said: "If I can figure it out , anyone can." Ah, if only that were true. I ask myself, "Is it possible that I am not the sharpest bulb in the drawer?"

The photo above shows the electrical connections I am unsure about. Does anyone know which wire goes where? The blue "OK?" with the red arrow below is pointing to the wire (that I drew a dashed blue line on); is this wired correctly?

As for the 1, 2, and 3, for each wire, there are red arrows pointing to what wire I'm referring to; but I don't know where these wires are supposed to be connected.

This above photo shows a device attached to the carburetor (a red up arrow is pointing to it). I don't exactly what this device does. The other red arrow points to a loose wire, is this wire supposed to be connected to this device?

 

The car starts perfectly and does run, but it runs a little bit rough.

 

Does anyone see any wrong wiring here? This is on a 1973 Datsun 610 Stationwagon with an L18 engine.

 

Thank you ... all help will be very much appreciated.
