    Mateo Thanks ,but I don't comprende 'trigger' -ie; one wire needs to connect to power amd the other needs to connect to points. I work on the theory that male plugs into power and the end product(points) plugs into female ??(just like a regular extesion lead)maybe I make up my own rules?? Just for the record I'm adapting these coils to a'74 Moto Guzzi with pointless ignition simple really ciao an dthanks Dutch

My 2002 Yamaha Road Star Midnight has no spark

Hi, Jeff orange wires are usually, but not always, power wires and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and CDI box.
5. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose, check for spark leakage in the dark.
6. Faulty ignition coil, pick up coil, trigger coil or CDI box testing needs to be checked with an ohmmeter at 70 degrees Fahrenheit
7. Faulty safety switches clutch, kickstand, neutral, off/on etc.
8. Faulty ignition switch.

How to disconect evs11 security system?

First look for a t harness. Disconnect at ignition switch and follow the wire down until you find the second connector. It will be possibly close to the evs11 or far down the wiring harness.You will need to follow the wires. you will find a connector down harness looks exactly the same as the one u pulled off the ignition switch. make sure it goes to the evs11 and to the car. Disconnect the female connector. Pull the male lower connector up to the ignition switch the t harness will look like the image. The two connectors are a male and female to the right of the picture. With a red locking tab that pulls out toward the part of the tab w lip.f433671d-bc09-475e-a5ad-cf995aa69ef7.jpg

I have a BG55 Stihl. I am replacing the coil. There are two blk wires w/female connectors. One attaches to the coil. Where does the other go?

It is most likley an earth return wire, it will fit either under one of the ignition unit screws, or there will have been a male spade connector under one of the screws for it to connect to.

How does the ignition system work on a 1969 CT1? I have no spark but the coil only has one wire and it seems to be a ground?
If the coil only has one wire (apart from HT lead to sparkplug) it will plug into the loom to the same color wire with the appropriate male or female connection. The hard mounting of the coil to the frame provides the ground in this case. This provides the continuity of the circuit from the contact breaker (points) behind the flywheel magneto. The site above has all the sections of your bike in exploded views with all part names. Cheers.

Vw camper T2 bay ignition problem

Please re-post your question as it sounds like you are talking about the later vanagon and not the bay-window type 2 since the bay-window units did not have fancy idle control and stabilizer units.

I have a yamaha yfm 350 moto 4 the stator was goosed so i ordered a second hand from ebay when it arrived the wires were a different colour on the bike the wires are green ,brown blue/white,red/black and...

MMM, fun... for a start the 3 whites should be right no matter which way they go, the other 4 i'd look at whether they have male or female conectors if possible, if they're bunched together etc, two should be from the ignition, and I think the other 2 are pos. & neg for the coil or coil + and one for earth, depending on the wiring of your bike

There was an old security system in my truck prior to me buying it and ive had it for six months and today i tried to start it and it wouldnt even make a noise turnig the ignition except for the radio and...

is the alarm factory or aftermarket?

If aftermarket - the brain will be under the dash attached somewhere near the steering column.

Look for an 10 or 12 Gauge YELLOW wire that has been cut.

This is your starter wire.

one half goes in one side of the brain, and the other comes out the other side.

either solder or use crimp-connectors to return this yellow wire back to factory.

If you no longer require the alarm - you can do the same for every other wire on the brain.

Here is the color code chart for your vehicle...

Constant 12V+ Red Ignition Switch Harness

Starter Yellow Ignition Switch Harness

Ignition Pink Ignition Switch Harness

Ignition 2 White Ignition Switch Harness

Ignition 3 Brown Ignition Switch Harness

Accessory Orange Ignition Switch Harness (Heat/AC)

Tach White Coil

Brake Switch White Brake Switch

Trunk Release Brown Switch or Driver's Kick Panel

Trunk Pin DIESEL- Glow Connector Blue behind Instrument Cluster

Parking Lights Brown (+) Light Switch

Head Lamp Yellow (+) Light Switch

Hood Pin n/a
