Motorcycle Ignition Coil –
Testing a motorcycle ignition coil is critical specifically when you install a new ignition switch. You will want to know if your installation was successful and that you aren’t possessing extra electrical issues. The great news is that you only want one gadget to aid you figure this out. An ohmmeter, also recognized as a multimeter, sends out a really low powered electric charge through a wire to measure how a lot resistance there is to the charge this is measured in ohms. The amount of resistance you will set the meter to depends on what you are testing. An information manual about particular testing for all kinds of resistance will usually be accessible in an automotive shop. Choose one particular of these up and head on outdoors to begin testing.
Tip: These information manuals can be really helpful for testing wiring in not just autos but most appliances inside the home.
Step 1 – Charge the Battery
Make certain your motorcycle battery is completely charged. This will guarantee the accuracy of your ignition coil testing simply because if you battery is not completely charged, it will be difficult to establish if the coil is the problem and not just a dead or weak battery.
Step two – Open the Coil Housing
Access the wiring for your ignition coils by opening the housing. Initial, turn of the engine ignition switch and make sure the ground cable for the battery is disconnected. Then, eliminate the fuel tank, and maybe even the bike seat, to access the coils and spark plugs.
There are some motorcycle models that will have the ignition coil be self-contained and situated right below the flywheel, which means this and the ignition starter coil are a single in the identical. However, it is largely mopeds and little European bikes have these types.
Step 3 – Take away the Plug Cap
Take away the plug cap for the test. This can also make your test inaccurate because the cap itself can add 300 ohms of resistance to your outcomes.
Step 4 – Get the Resistance
Measure resistance among low-tension, or main, wire and ground terminal wire. Your result need to be very low about .five to 1.5 Ohms. If you are not positive about which wire the principal is, it will be the small a single going towards the CDI box or CDI points.
Subsequent, measure resistance among the high-tension, or secondary, wire and ground wire. This result should be high about 6000 to 13000 ohms.
Step 5 – Study the Final results
If the resistance in between these wires is outdoors the indicated numbers, then it is probably your ignition coil is bad. There are instances when an ignition coil will function fine whilst the engine is cool but begins to fail when it warms up. If you are prepared to spend a tiny much more, there are machines that can test ignition coils under stress.
Step 6 – Test the Coil
Yet another simple test you can do, regardless of the variety of coil you’re dealing with, is to check the voltage flowing with battery connected. If you are acquiring close to 12vdc at the coil terminal of a 12V DC technique and no reading is coming out of from touching the coil, then you either have a undesirable connection or bad coil.
When you know for positive whether your ignition coil is bad, you can take measures to either replace it on your own, or you can take your motorcycle to a pro for repairs. Hold your readings recorded so you can offer them to a mechanic if asked.
