    My question was for the wire leads going to the starter relay (not the starter)-my son took the old relay off without marking how to connect the wires to the new relay.

  • stevgreenart Mar 20, 2011

    OK-we're getting closer. His relay has a total of 6 connectors-2 pair are labled 'on' and are arranged like this: ==. The other pair are labled 'coil' and are set side by side: l l. So the whole arrangement is: l l
    = =
    This model has 2 coils.
    Thanks,
    Steve

    I need a wiring diagram, or picture of the wires that connect to the starter relay for a 1985 Nissan truck. It is a four cylinder engine with two spark plugs per cylinder and two coils. The relay has 6 connectors. and the wire colors are: black, red, white, white with red line, white with blue(or green)line, and brown. Which wire goes where?

  • stevgreenart Mar 22, 2011

    ZJLimited,
    Man this is a heck of a lot closer than before-wire colors too. I'm not sure what year the schematics refer to (no coils?) but I still dont see a six-input starter relay related item.
    Any others?

    jturcotte,
    Wow, this is the closest yet. The only difference is that the unit that was removed, and the replacement don't match real close withyour photo example. The one we have is all plastic, approx. 1/2"X1/2" by 3/4" tall. The spade connectors on the bottom are arranged 2-pair side by side and are labeled 'on' for all 4. The other pair are set at 90 degrees from them and are labelled coil.The top chematic on the repplacement shows on-com and on-com and the seperate pair are labelled coil-coil. The orig was called Niles #25230C9925. The replacement he got is labelled JD141M. Maybe they look different because of manufacturer/year?
    Thanks a bunch
    Steve

Hi, the relay you describe is not the starter relay but the EFC main relay. In the diagram below, the colors match except what you are seeing as a while wire was probably yellow at one time. This is a double pole relay. The wiring is fairly simple, but I would need to know the names of the terminals on the relay to match the wire colors up. There should be 2 terminals for the relay coil and 2 each terminals for the circuit 1 and circuit 2 power and loads. Since the relay coil is usually indifferent to polarity, you only need to get the pairs right. The coil pair is brown and black. The circuit 1 pair is white/green and red/yellow, and the circuit 2 pair is white/red and yellow (or white if yours is faded). Does this makes sense? If you have the old relay and can read the names of the terminals, I could give you a complete match of wire color to terminal. Please let me know if you have questions.

    In the example below, terminals 1 and 0 are for the coil, so they would get the brown and black wires.

    circuit 1 is at terminals 2 and 4, which would get the white/red and yellow wires.

    circuit 2 is at terminals 6 and 8, which would get the white/green and red/yellow wires.

    Hi, sorry I went ro bed and now another expert has been assigned. Nevertheless, you are there on the problem. This picture was just an example. Your relay is pretty much the same though. It is indifferent to polarity, so you can hook it up just as I said above. The brown and black wires go to the coil terminals. Then along the row of 4 blades, the colors would be white/red, faded yellow, white/green, and red/yellow in that order.

There are 4 wires which go to alternator.In that 2 white wires go to battery.1 black wire goes to ground and 1 yellow/black goes to bulb check relay.The starter has only two wires
the big one goes to the battery and the small one goes to ignition system. You can not mix the terminals because the size of the studs on the starter.

    Connect the smaller
    terminal or terminal post marked SIGNAL, SWITCH or IGN to the ignition switch.
    This terminal goes to one side of the magnetic coil inside the relay. The other
    side of the coil is connected to the other smaller terminal which may be marked
    negative or ground. This should be connected next. Normally it is connected to
    the frame or to the battery's negative terminal.


    Make sure the negative relay coil lead is
    connected to ground with the vehicle in neutral.

    It's a blue relay.It has 4 wires going to it with 2 connectors the
    connector with the larger gauge wires power the starter when the relay
    engages.--You
    can jump from the battery to one of the starter relay larger wires , its
    black with pink or black with yellow and the starter should take off.----
    The black with pink striped wire from the blue relay goes directly to the
    starter solenoid
    so jumping from the positive battery post to that terminal
    should make the starter take off .The
    black with yellow wire gets power from the ign switch
    when in the start
    position and the same thing with the black / yellow smaller gage wire the blue wire with a green stripe is a ground
    for the relay when the clutch switch is depressed - the power for the ignition
    switch comes from the fusible link off the battery so check those links
    carefully and check to make sure you have power to the terminals for the blue
    relay when the key is on start for both the black/yellow wires a multi-meter is
    good I like to use a test light for problems like this if you can't get the
    starter to go by jumping the black/pink wire ,if nothing happens then there is
    an open circuit between the relay and the starter solenoid.



    ---------The fusible links supply the
    power for the ignition key and starter you should have 12 volts or a bright
    test light at the black/yellow wire for the starter relay both the large and
    small black/yellow wires have the 12 volts the blue/green wire is a ground for
    the relay that comes from the clutch switch.
    The blue relay color may differ.But in most cases its blue.---

    this should help.Thanks.Helpmech.

    The pair labelled coil.The one connects to ignition switch harness and other terminal of coil pair connects to the negative terminal of battery or chassis.

    see the fig below:---

    also see the diagrammatic view of the relay connections in twin coil :----



    If this above image is very small then.Click the link below for big image view:---


    -----

    In the picture there is one more relay shown, that is fuel pump relay.ignore that relay.Just concentrate on main relay, that is stater relay.

Have you checked the relay in the circuit. You really need a schematic of the wiring diagram. Electrical can be tricky without the wiring diagram.

2003 buick century spark plug wire sizing chart


I doubt very much if you will get a HT length chart to help you, but if they are all various lengths, it usually goes that the longest to the furthest plug working back to the shortest in the firing order.
leads should sit comfortably without strain or being too loose
use lead spacers to keep the leads from touching each other or you run the risk of a misfire as the spark is induced into the lead with the less resistance ( induction stroke where there is no compression)

I have a Mitsubishi lancer 2000 and have taken the wires off the distributor in order to change the spark plug leads without concern of how to put them back on. Any ideas on the order


4 cylinder, firing order normally 1342. Take off distributer cap, set engine with number 1 cylinder on top of compression stroke. you may have to take out the number one plug, turn moter by hand and feel for compression with finger on hole. Look where distributer rotor is pointing and match with distributer cap. That will give you #1 lead position. Follow around cap in rotor direction and you will get the rest.
6 cylinder normally 123456. same story.
if you still have the old leads, they are sometimes marked and normally different lengths. if you lucky, and replace them, you can sometimes pick up which went where by the bends left in them over time. Then start again and mark them. I normally replace leads one at a time. Safer and easier. Or Photograph them with cell.

Need firing order diagram.. wont start


remove the dizzy cap, crank motor over to find out the rotation of the rotor. Remove the no.1 spark plug and bring no.1 piston up to top dead centre on compression stroke, mark side of dizzy body where the end of the rotor points to, replace dizzy cap and see which lead it lines up with.
that will be your no.1 lead, find the firing order and put the leads back on the dizzy cap in the direction of the rotors rotation, run those leads to the corresponding plugs and it should start.

No shift or gauges on 92 Chevy 454


i would first look at the main harness going to your ecm(engine control module) there is a 60 pin connector the bolt that hold the connector is a 10 mm remove the bolt and remove the connector it should be clean with no burn marks to show signs of a short. if there are burn marks not only must you replace the connector but you fried the ecm as well and that needs replacing. also check your relays. often times even though you don't blow a fuse the relay still may short out. this is a good place to start. let me know the results

Need radio wire diagram


join www.kiatechinfo.com.

This website is the technical portal for Kia, for all models it has system schematics and parts diagrams. Only today I rewired my '02 Rio by using the schematics. Just took four hours to cut, crimp, solder and shrink, and gave me a crook neck. Also, on the diagram, from the rear connector, the side that has the black lead - ground - contains the positive speaker leads (R/B, LG/Y, W/G, Y/L(blue)), and the side that has the ACC+ and MEM+ contains negative speaker leads (R/G, LG/R, W/R, Y/R)
