Expert 240Z Ignition Wiring Diagram Help: 71 240Z Dash Wiring, No Start Or Lights. - Trouble Shooting - Boy, did i chew off lots with this one. But, these three circuits all come together on the hazard switch, so i chose to take at the mission and examine them suddenly. I used the 72 fsm as my guide. I'm together with a pdf of this analysis as nicely. Holy crap. Properly, one smooth fix is that last photograph... That is the piece that connects the horn button to the horn relay wiring... It mounts on the left facet of the turn sign transfer, facing in closer to the driving force, and the little spherical contact point is spring loaded closer to the steering coupler, so that it can maintain a touch and permit a connection to the horn. Make experience?. It has a msa fusebox hooked up by way of p/o. Uncertain if set up is correct. Two white/purple wires are coming in and connecting to right facet screw submit. Single (white and blue?) Wires are linked from one facet to the opposite at the fuse field. I am uncertain if that is oem or no longer, however these yellow, yellow/crimson, pink/blue, and inexperienced, wires appear to run collectively, is that this accurate? I accept as true with the yellow wires have something to do with the gauges?.
For the alternative stuff... I might suggest replacing a lot of your wiring. Also, i'd advocate reading the factory service guide wiring phase, together with the sprint wiring, and specially the entire wiring diagram for the car. Once you understand it with the aid of heart and might perceive what every wire does, simplest then must you in reality begin hacking away on the harness. There is a lot of stuff previous owners have performed that isn't always in the fsm, and you will have a hell of a time figuring it out. Also, it sounds such as you probably have a few corroded connectors somewhere, if you are best getting .2v off the key. I might begin at the ignition transfer, and paintings my way from there, cleansing all connectors, the usage of a few dielectric grease to ensure an excellent touch, and checking them, separately... Until you die of vintage age. Holy crap. Properly, one smooth repair is that ultimate photo... This is the piece that connects the horn button to the horn relay wiring... It mounts at the left facet of the flip sign transfer, dealing with in towards the motive force, and the little round contact factor is spring loaded towards the steering coupler, so that it could preserve a touch and permit a connection to the horn.
