Turn your ignition switch on, using a test light or volt meter, see if you have power to the coil. If you do, you should have power to your ignition unit. According to the wiring instructions from Crane, the power for the unit comes from the same wire as the power to your coil. The trigger wire goes to the other side of the coil. Then there's a wire for the VOES but this would not have anything to do with the unit functioning or not.

If you wish to test the "Run/Stop" switch, with the test light or voltmeter on the coil, and the switch in "Run", you should have power to the coil. Fllip the "Run/Stop" switch to "Stop", the voltage goes away. Some bikes will allow the engine to turn over with the switch in "Stop" position or if the switch is defective. On some bikes, the switch does not disable the starter.

Now, check your coil. Using the DVOM (digitial volt ohm meter), disconnect the wires on both sides of the coil. Put the meter in OHMS, R X 1 postition. Put one lead on each small terminal of the coil. Your meter should read between 2 and 3 ohms, with 2.7 being a typical reading. If it reads more or less than that, the coil is probably bad.

In the event you don't have a meter, there's a simplier way to test it. Leave the "HOT" side of the coil connected but disconnect the red wire from the ignition unit. Disconnect all the wires from the other side. Now, make up a jumper wire and connect it to the negative side of the coil. Turn the ignition on and MOMENTARILY ground it on the engine. When you take the wire loose from the ground, you should see a spark at the spark plugs.

I hope this helps.

Good Luck

Mobility scooter stops dead. I turn key off and back on it will go again then stop

Check your battery terminals are tight. It sounds as though they have come loose, or you didn't do them tight enough when you changed batteries. Perhaps clean the terminals both on the leads and the batteries, and finish with a wipe of Vaseline to keep water at bay. Good luck.

1984 Yamaha Venture Squealing somewhere towards the front end of the bike.

Unhook the speedo cable at the wheel and zip tie it up somewhere safe so the cable doesn't fall out of the sheath, and test ride. If the squeal doesn't go away it's the speedometer gear or something else at the wheel. If it does go away the bearings in the speedo itself are drying out. You'd then have to pull the cluster, fit a pipe cap with a grease zerk threaded to it onto the back of the speedo, and grease with appropriate bearing grease which I believe is moly grease.

I changed the oil in my 2000 XLC 883 Sportster and when I started it up the oil/dip stick blew off and oil spilled out. I put three litres of oil in - same as last year. Could it have been an air bubble?

To begin with, the capacity of your Sporty's oil tank is 3 quarts, not 3 liters. A liter is slighly more than a quart and the oil tank on the bike is designed to hold three quarts of hot oil. Oil expands when it gets hot. If you notice the marks on the dipstick, the lower mark is "full cold" and the upper mark is "full hot". Never overfill a Sporty.

Now, if the bike had been sitting for a while, they have a tendency to "oil sump". Oil sumping is a condition where oil seeps past the check valve in the oil pump and builds up in the bottom of the crankcase. Any Sportster and any Big Twin prior to the Twin Cam that has the oil tank located higher than the engine will do this. That's why the older Harley's would "puke" oil out of the breather when restarted after sitting for a while. If you had a half quart of oil in the bottom end and then poured three quarts into the oil tank, you were overfilled. That's one reason to always start the bike and run it until it's at full operating temperature before you change the oil. The warm oil drains easier and there is none left in the bottom end to play a nasty trick on you. This event happens quite often. You are lucky in the fact that the oil plug didn't blow off while you were riding down the road. When that happens, you get covered in oil. Not something anyone would like.

Good Luck and Ride Safely

1990 virago 535 starts and runs great for about 3 or 4 miles

Pull the float bowl caps off the carbs and then spray carb cleaner into the main jet and all other accessible ports on the carbs. Chances are there is a build up of water condensation in the carbs.

2009 Street glide idles poorly, strong gas smell, stalls

The 09 models come with a "parade" mode which causes the rear cyclinder to quit firing when idling in traffic etc to combat over heating. You should be able to kick it on by rolling the throttle grip FORWARD for 5 to 10 seconds. Have you changed the pipes or air filter? If you have and never had the EFI adjusted (either factory download or fuel tuner installed) your bike could be running extra rich causing the over heating and eventual engine destruction. New Harleys run rich from the factory, any changes to the intake/exhaust system without proper fuel injection management will cause overheating. Try getting your bike into parade mode by rolling the throttle forward to the stops for a few seconds, that will cool things down.

My honda cbr 600 is struggling as if it keeps running out of petrol. whats happening?? Having a similar problem. I've had a 1996 CBR600F (50 000km) for about 14 trouble free months until recently. The...

It all seems to be leading to fuel starvation. Have you checked the tank breather is not blocked which can be a small hole in the petrol cap or a tube from under the tank. It could also be a blocked fuel filter. There should be two. One inside the fuel tank under the petcock, another before the fuel pump. Here is the workshop manual where you can find all info you will ever need for this bike.

Thanks and good luck.

95 sporster speedometer

The timing of the plug change is probly chance Your speedo is a cable run from your front axle spacer between fork tube and Bering a spark plug or a wire could only put out the speedo light not affect the speed sensors caus there isn't one one a 95 sporty I only know cause I took off every thing on my chopper but headlamp tail lamp and starter switch and I had to make a custom spacer to take the place of my speed sensor slash Bering after I ditched my dash years ago on my 93 evo sporty

99 vstar 1100 quits when put in gear

couple of things to look for.

1. when you're putting it in gear, is the kick stand up or down. if down, most modern day bikes have a kick stand safety switch which will not allow you to put the bike in gear with the side stand down. this little relay may have failed. its usually located near the kick stand.

2. clutch disks may be stuck together. it happens on my old bikes from sitting too long (over a winter). when i pop it into first gear after i start it w/ clutch lever pulled, it will buck forward and die. i have to repeat a few times to get them unstuck.

good luck

Carb issue

are you running the stock airbox??? stock jetting? i dont think those stock needles were adjustable. (i could be wrong on a 79) so they may be aftermarket needles. how many turns out do you have the air/fuel screws? how does it run down the road? does it run better on the high end or low or just bad all over? or can you even ride it?
