Hmm... that's a very specific question.. could be anything! probably better off checking a forum specific for your bike.

google for "yamaha xj 650 forum" and you're sure to find some fellow riders who would know.

No spark from coil to distrubuter


Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

Batteries don't last


Check the battery connections to the wire ends for corrosion and tightness. Take the wires off the battery and remove any obvious corrosion. Take a knife blade and make the wire end shine and the same for the battery terminals. Reassemble the wires to the battery and tighten.

Why do my spark plug wires I'm my 1994 ford


Probably not seated well on the plug. When you push the plug wire boot over the plug, you have to make sure the wire end terminal's ring end snaps onto the spark plug. It is not connected tight until you hear the wire's end terminal snap or click onto the tip of the spark plug. If you can't hear the snap, the end of the wire may not be seating onto the spark plug tip. Push the boot back away from the spark plug wire end to investigate-the boots can get very stubborn with age-keep twisting it and pushing it till you get it moving back from end of wire. Examine the metal end tip of wire-trey to snap a spark plug down onto it now-if there is a problem with the end terminals you will see it-it may be too big to snap over the spark plug tip and hold securely, or if the ends are bent, use pliers to straighten them out. If these are aftermarket spark plug wires, the end terminals may be too small to go over the spark plug tip. You would then need a new set of spark plug wires.

I suspect you just have not pushed the wires down far enough to seat them on the plugs-push the wires onto the plugs until you hear them snap or click. Then they are seated firmly, and should not be popping off.

Kia sedona problems starting


Kia Sedona known for electrical grounding problems. Before spending any money, follow thick wires from battery negative terminal to body and to engine block. Disconnect and clean each connection, use oscillating sanding tool and #400 grit to polish the surface where negative wire connects and to polish the terminal end of the wire too. If unable to find a negative battery wire to engine block or transmission, buy one at Walmart $8 and install. You may need to replace your negative battery terminal to accommodate another wire. Most likely by cleaning the grounding or providing an express engine ground, your original electrical problem will have disappeared along with many others you may not have noticed. Be sure to remove and clean both battery terminals and connectors too.

How to replace freeze plug on 1998 dodge ram pickup


Use your crescent wrench to disconnect the positive and negative battery cables. Be careful not to touch both battery posts together with your wrench, as this will damage the battery and possibly harm you.

Use your spark plug socket to gently grab the insulated end of the spark plug wire; pull it away from the tip of the plug. The spark plug socket looks like a regular set of pliers, except that the jaws have rubber inserts to grip the insulation without damaging it. The plug wire itself looks like a 15-gauge wire with a rubber boot on each end: One end is connected to the spark plug present in each of the eight cylinders, while the other end is connected to a coil pack terminal, usually located on the right rear side of the engine compartment. The coil pack is a square, black, solid-state component that has eight terminals for each of the eight plug wires.

Use your spark plug socket to gently pull the coil pack end of the plug wire away from the terminal. Repeat the last two steps until all eight wires are removed.

Consult the service manual for your vehicle's year model and determine the exact firing order. You will need to connect each new wire to the numbered coil pack terminal and the corresponding engine cylinder. Failure to replace the wires in the right order will result in failure of engine operation.

Use your crescent wrench to reconnect the battery cables (black wire to black terminal, red wires to red terminal).

Start the vehicle and make sure it is running smoothly. If you hear misfiring in the engine, use the spark plug wrench to make sure all the connections are properly seated. If the condition continues, you will need to further diagnose the electrical system.

Hi Bennymullins, and the usual suspects are:
1. Plugs in bad condition, wrong type or number or partially fouled.
2. Spark plug cables in bad condition or leaking.
3. Spark plug gap to close or to wide.
4. Faulty ignition coil, module and or sensor.
5. Battery nearly discarged.
6. Damaged wire or loose connections at battery terminals especially the ground cable at "BOTH" ends, ignition coil, or plug between ignition sensor and module.
7. Intermittent short circuit due to damaged wire insulation.
8. If your bike has a CKP sensor you must leave both plugs in
head and check for spark with a 3rd plug. Good luck and have nice day.Harley Davidson Wiring Diagrams and Schematics

1997 VW JETTA DIESEL GLOW PLUGS


The glow plug relay is responsible for the duration of glow plugs, this needs to be the starting point. You should get a 12v out for so many seconds when ignition is switched on.
I have taken the cover off relays in the past, cleaned up the internals, sprayed with circuit cleaner and got plenty more years out of them, worth a try.

The thicker negative wire should go to the engine for a ground. You should be able to move the wire around to different points on the engine and you should find where it broke off of the end terminal.

Does the car seem to be "turning over" slower than normal?
