SOURCE: Following my bike's fall, the bike will not start ...

Hard to say depending on how hard the bike fell etc. If you damaged the stator in the fall that would be one explanation for it not starting and the battery not holding charge. If it's got fuel and spark it will start. If you have a reasonable amount of fuel in the tank the petcock won't create a problem unless the fuel is off, but there should be enough in the carby bowl/s to get it to fire and run. Any problem of excess fuel in the combustion chamber after a fall should dissipate in a few hours. Try and ascertain if you have a spark by taking a plug out, reconnect to the lead and put it against the head so it earths and kick over. Don't touch the plug - nasty current and dangerous, especially if it's CDI. You will soon see if you have spark or not. If the spark is OK it will be a fuel problem. Also, if it has a kill switch check it wasn't accidently bumped into the off position in the fall. Good luck

SOURCE: My horn doesn't work(my bike's

To fix your horn is easy, there are some excellent pills out there.
The bikes horn though is different, you will need a small test light or multy meter,
Check if there is power to the wire plugged onto the horn, ignition on
The horn needs direct power to one terminal, and the other terminal shorts to earth through the button.
If there is power and the other wire connects to earth, when the button is pressed you probably need a new horn( not that expensive)
If there is no power check the fuse
If the second wire doesnt connect to earth when the button pressed there may be a problem in the handle switch.
There can also be a problem in the wiring if it has been damaged in the steering stop etc
Sometimes the horn can just be stuck and a small tap on the horn with the button pressed can start it.
If the horn button it a bit corroded in the contacts, hold it in and wiggle it a bit, can clear the corrosion.

Sometime easier to just check the fuse then buy a new horn, before chasing down the wires and switches

When i kik to start the bike inside the engine slipping


The most likely problem is that the kickstart gear has worn. It shouldn't be difficult to replace as it should be on the outside to the gear cluster. You should be able to get at it by removing the casing and it should be visible. To do the job (or maintain any motorbike yourself) I would suggest that you buy a manual. They only cost about 20GBP but if you follow the instructions in them they will save you hundreds. And make the next bike easier to work on. The Hero is based on the CG125, a very reliable and useful machine.

      Make sure the key and kill switch are both in the "on" position. Ensure that the proper starting procedures for your bike are followed. Is it in neutral? Clutch pulled in? Gas in the tank? Then try to start your bike. Does it turn over? If not, check to see that the battery is properly connected and the terminals are not corroded. If they're loose or dirty, clean and tighten them. Then, using a voltmeter that measures ac/dc and ohms, check to see that your battery has enough charge to crank the engine. If not, replace or charge your battery and try again. If it still doesn't turn over, there may be a loose connection between your battery and starter; a bad ignition or starter switchl or a bad safety relay. Check a repair manual for proper testing procedures for your bike, as each motorcycle differs.

      If your bike turns over but doesn't catch, check to see that it's getting fuel. If the bike has a fuel petcock, make sure it is in the "on" (or, on certain bikes, "prime") position. Then remove the main fuel hose and check to see that fuel is flowing freely. If fuel isn't getting to the carburetor or injection system, your bike won't run. If that's the case, your problem is likely something in the fuel system. If fuel is flowing freely, reattach the lines. If it's not, check to see if the fuel filter is clogged, if a line is pinched or if the petcock is working properly. One way to determine if the problem is in your fuel system is to put a few drops of fresh gas into each spark-plug hole, replace the plugs and turn the bike over. If it starts and then quits, the problem is likely in the fuel system.

  • If you're getting fuel and the bike turns over but still doesn't catch or start, check the spark plug or plugs. Start by pulling off a spark plug wire, then removing a plug using the spark plug socket supplied in your bike's toolkit. Now inspect the plug. It should not be wet (usually caused by fuel, when the plug is not firing) or coated in carbon/burned oil deposits. Now check to see if the bike is getting spark. Although you can get a special, insulated set of pliers to hold the plug, there's a "quick and dirty" method for this: After reattaching the plug wire, lay the threaded part of the plug against the engine (not over the plug hole, as the spark could ignite any fuel that is blown out when you try to start it). Now, making sure you're not in contact with the engine or plug, hit the starter. You should see a nice blue spark. If you don't, make sure the threaded portion of the plug is touching the engine (but the electrode is not) and try again. If you still don't see a spark, you either have a bad plug or a problem with the electrical system. Check to see that all the ignition wires are properly connected and that you can't see any cracks in the wires. If the wires are cracked, they should be replaced. If you're still not getting spark, it's time to consult a repair manual or call a mechanic.

    If you've got fuel and spark, ascertain that your bike is getting enough air. Start by pulling off the air filter. If it's too dirty, you won't get the proper mixture of air and fuel in the carburetor or injection system. If it's clean, check to see that the air box is properly connected-- a loose hose or air leak can feed too much air into the system. If your bike is equipped with a choke, ensure that it's able to move freely and is not stuck in the "on" or "off" position.

    If you've followed these steps and still can't get your bike to run, call in an expert. If you think you've narrowed down the source of the problem, describe the steps you've taken to point the mechanic in the right direction.

    Might be a faulty side stand lockout switch. They're subject to a lot of wear, tear and grime and tend to wear out. So your bike thinks the side stand is down when it isn't locking your bike out so it won't start. Failing that it may be a faulty neutral switch, again the bike doesn't know it is in neutral so doesn't start.
    I am going to state the obvious also, is your main kill switch turned on?

    How do I test the starter switch on a 2001 Honda Shadow 750 ACE Deluxe


    Maybe I am missing somethtg here ... you press the start switch and one of 2 things happens - the bike starts or it doesn't. If it does, your start switch is definitely good. If it doesn't ... well there are a couple things to consider. Are you in gear? Will not start in gear unless the clutch is pulled in. But, if the clutch is pulled in and you are in gear and the side stand is down, it will not start. So, if you move the side stand up, you are in gear and you have the clutch pulled in and it doesn't start ... well ... could be the key is not on (silly but true) and/or the 'kill switch" may be in the off position causing your bike to not start. If the clutch is pulled in, the side stand is up and you are in neutral and the kill switch is in the run position and the key is on - (or some other very similar arrangement as I have described) your Shadow should start. Nothing here has ruled out a bad switch nor, for that matter, a good switch.

    You bike will still not start - so what else to look at/for. How is the battery? Have you checked it recently? Your battery MIGHT still be the original in which case I would be suspect of it being 10 years old. Maybe you or a previous owner has replaced it ... still, have you checked it? You will find it under the seat.

    Battery good and still will not start? Find the start solenoid. With a volt meter, measure the voltage at each of the large terminals. One shold be 12 volts (battery side) the other should be zero volts (starter side). You will check the smaller terminals later . Key Off? No volts on smaller terms. With everything in a normal start condition (key on, bike in neutral, kill switch in run position), measure the voiltage on the other large terminal on the start solenoid. Should be zero. Press the start button. Do you get voltage? No voltage = the solenoid is either not receiving power to energise or it is energised but not making connection.

    What happens is when you turn on the key you supply power to potentially anything that can be turned on. When you press the start button, you should be powering the start solenoid (an electric operated switch) That should allow power to flow to the starter and start the bike. If all that is happening, I would suspect the starter. If everything is OK but it doesn't start, suspect the solenoid and lastly ... the switch. I think I would consider jumping power directly to the starter to see if that actually runs before looking at the switch. The actual start switch is pretty tuff compared to other parts of the system.

    Let me know what happens ... good luck. I think you will find something simple.

    Thanks for your question @ FixYa.com

    Voltage issue. With the bike running, remove the negative terminal off of the battery. If the bike stops, it's the alternator. If it doesn't, have the battery tested. Possibly dead cells in the battery. If that still doesn't work, let me know the model year and we can go from there...

    Check your manual. I'm not sure what year they started putting them in, but there is a gas shutoff safety that will activate when the bike is on its side. It is re-settable.

    Cutmaster 81 plasma cutter when turned on, starts normal but air solenoid keeps going on and off. What could be the problem?


    Hi:

    Sound like you have a faulty start cartridge, probably you used the torch handle to bang a metal part to make it fall. This is a common problem when using the gun as a hammer. Just replace the start cartridge. Before changing it; check the cartridge's lower end, this must move freely up and down.. If you did replace the cartridge already then probably your output power pc board it's damaged.
