    no it does not have a pink wire like the previous wire that I owned. I believe I will have to run a wire to the negative side of the coil. Harley in 2004 started to change things around. thanks for response. olddice

    It was figured out today, tach is working. Here are the answers? You hook up your tach,red- power to ign, blue- to headlight, black to a ground. green wire, you must run a wire to your ecm. there is a slot for a tach. that is the power module behind your battery- mine was slot 3. Harley davidson on 2004- and newer did not offer the optinonal tach read out wire(pink). anyway it slot number 3 in the power module (ecm) will say tach for a 2005 night train. a good crimping tool is needed because you will need a male adapter- doche wire crimper to attach your tachometer read out. It is there and it does work. good luck please notify me for a better explaintation. safe ride to all.

Yeah, that's what I was talking about. No pink wire on the later models but I'm sure they've got a wire for the tach on some the models that come with them. If you had a wiring diagram for one of those it would tell you what color they use now. But, if you only have one wire coming off the coil, that means there isn't another wire for a tach, Uhh. I wonder if the later models get the trigger off the crank sensor or maybe out of the ignition unit rather than the coil.

    Thanks for the information. I was thinking that the later models would have a connection somewhere other than the coil. But, since I don't know a lot about the newer computer controlled bikes, I would not have guessed it would be on the ECM. I would have figured it would be on the ignition module. That's why I don't work on them. I work on 1999 models and earlier. Panheads, Shovelheads, and Evos are my speciality. That's why I've got a picture of my '65 FL as my avator or whatever that picture is called. Now, I'm telling my age. I'm 60 years old. Glad you got it going and thanks again for the information. Ride Safely now.

How to i test a coil on a 1986 H-D Softail?

Disconnect the wires from both ends of the coil. Use an ohm meter to test the resistance of the primary winding in the coils. Put the meter's function switch in OHMS, R X 1. Touch one meter lead to each of the small terminals on the coil. Your meter should read 2-3 ohms. If this is correct, connect the "HOT" wires (the pink ones I think) to the coil. On the other side, take a length of regular wire and strip the insulation from each end. Connect one end of this wire to the empty terminal of the coil. Put an extra set of spark plugs in the spark plug wires and ground them on the engine so that you can see them. Turn the ignition switch on, and MOMENTARILY touch the bare end of the jumper wire to the engine case. When you take the wire away from the engine case, the coil should fire and you should see a spark at the plugs. If no spark or the resistance reads other than between two and three ohms, the coil is bad. If the coil checks good, I'd suspect the pickup in the timer cavity on the right side of the engine.

Thank Steve for this

Blows ignition fuse wont start

If it's blowing a fuse, it's got a short or the coil is bad. Check all the wiring associated with the ignition circuit including the tachometer if the bike has one. Test the primary circuit of the coil. Disconnect the small wires going to the coil. Use a Digital Volt Ohm Meter and put one lead on each small terminal of the coil. Put the meter in "R X 1" postition. You should read 3-4 ohms. If you read zero or less than 1 ohm, the coil is shorted.

Good Luck

Cant find the tach sensor on a 2000 1200 sportster

The tachometer is an electronic tach and gets it's "pulses" from the ignition coil. The older bikes had a pink wire that went to "negative" side of the coil. The negative side of the coil is the side the electronic sensor plate in the ignition cavity on the right side of the engine connects to.

All the original tachometers that I've ever seen had an orange wire and a pink wire. The orange wire was the "hot" or power wire. The pink wire was the 'trigger' wire and went to the negative side of the coil.

Where is the ignition control module on an 1989 totota camry

Toyota Camry 1983-1996 Repair Guide Ignition Module - REMOVAL & INSTALLATION

All engines, except the 2S-ELC, have an external igniter.
  1. Turn the ignition key to the OFF position. Disconnect the negative battery cable.
  2. Separate the wiring harness connections.
  3. Unbolt the igniter.
  4. Loosen the nut holding the wire lead onto the coil.
  5. Tag and disconnect the wire lead.
  6. Lift the igniter off its mount.

To install:
  1. Mount the igniter to the bracket.
  2. Attach the wire lead to the coil.
  3. Connect the harness.
  4. Connect the negative battery cable. Reset any digital equipment such as radio memory and the clock if necessary.

See Figure 1
The internal igniter is only applicable to 2S-ELC engine Camry models. All other engines are equipped with an external igniter assembly.
Review the complete service procedure before this repair. Note position, color of wire and routing of all internal distributor assembly wiring.
  1. Disconnect the cable from the negative battery terminal.
  2. Remove the number one spark plug. Place a finger over the spark plug hole and rotate the crankshaft clockwise to top dead center. When there is pressure felt on the finger at the spark plug hole, this will be top dead center of the compression stroke on number one cylinder. If not, repeat the procedure. Install the number one spark plug.
  3. Mark the position of the distributor flange in relation to the camshaft housing. Remove the IIA distributor assembly.
  4. Remove the distributor cap with the wires attached, and remove the packing. Mark the position of the rotor relative to the housing and pull the rotor straight up and off the shaft. The distributor cap is held to the housing with three retaining screws.
  5. Remove the ignition coil dust cover.
  6. Remove the two nuts and spring washers and disconnect the four wires from the terminals on the side of the ignition coil. The wires are color coded yellow, blue, brown and red.
  7. Remove the four retaining screws and remove the ignition coil and packing.
  8. Remove the nuts and disconnect the pink, white and black wires from the igniter terminals. Remove the two igniter retaining screws and remove the igniter.

To install:
  1. Attach the new igniter with the two retaining screws. Connect the pink, black and white wires to their respective terminals and install the nuts. Make sure that the pick-up coil wires are secured in their clips and that there is slack in the wires.
  2. Install the ignition coil and attach it with the four retaining screws.
  3. Connect the four ignition coil wires to their respective terminals and install the two nuts and spring washers.
  4. Install the coil dust cover and push the rotor onto the shaft.
  5. Place the distributor cap and wires into position. Install and tighten the retaining screws.
  6. Install the distributor assembly and connect the negative battery cable.
  7. Connect a tachometer and timing light to the engine and adjust the ignition timing.


Fig. 1: Make sure you remember where the colored wires attach for installation-2S-ELC engine
  1. Reset any digital equipment such as radio memory and the clock if necessary.

  1. Remove the distributor cap, rotor and di-electric insulator covers. Disconnect the red and yellow wires from the coil and the pink, white and black wires from the igniter.
  2. Remove the igniter. It may be necessary to mark and rotate the distributor to gain access to the igniter retaining screws. The timing should be checked after the distributor is returned to the mark.

To install:
  1. Install the new igniter using the two new retaining screws.
  2. Twist the pick-up coil wires together, install the white wire first then pink and black wires to their original locations. Make sure the wires do not touch the housing generator or advance plate.
  3. Route the red and yellow wires from the igniter so they do not contact moving parts. Connect the red wire to the right coil terminal (with the brown wire) and the yellow wire to the left terminal (with the blue wire). Replace the covers, rotor and cap.
  4. Connect a tachometer and timing light to the engine and adjust the ignition timing.

Hope this helped (remember comment and rated this).

I amcurrently searching for a diagram to wire up my RPM gage but I don't know where to put the wires!!!! I really need help!! thx:)

The RPM guage (tachometer) reads the spark impulses from ground terminal of the high voltage sending unit. I've never had to install a tach on an Accent, but for the most part the wire (on other model Hyundai's) is green and connects to the distributor primary or negative (-) side of the ignition coil. And then to the Tach terminal. Do not connect to coil on If yours is an MSD ignition, do NOT connect to the coil!!. Some electronic ignitions have a tach terminal on the ignition box, the green wire may connect there. Hpe this helps....
