These newer motorcycle starters work at the push of a button. within range. 2. If these tests do not check out, you will need a new regulator/rectifier. This process is more commonly known as turning the engine over. Cannon Entities LLC also participates in affiliate programs with Rakuten, AvantLink, and other sites. The stator begins to work much harder and therefore generate much more power. If the battery reads 12 volts or less, it . Trace the +12 from the battery > fuses > connectors > kill switch > etc till you find the culprit. Suppose a motorcycle experiences a power overload, and the voltage regulator cant compensate for the flow of electricity. You can then test the coils as they are being warmed up. What are the Main Causes of Road Accidents in the UK? A good way to test this is to wait until it wont start. If you are needing to save money this can cut the cost down immensely. setting your meter to Ohms. This can also prevent the starter from being able to engage properly with the flywheel. The battery drops to 10.8 volts when starting, i assume that means its getting weaker. How to Avoid a Tyre Blowout And How to Handle One if it Happens, Nine signs and symptoms of a bad brake caliper and how to fix it, Nine signs and symptoms of a failing front or rear differential, Is your driveshaft failing? The opposite can also happen with the low-speed coil. Your You will want to file off any sharp edges on the stator. It should read in the thousands for Ohms. Instead, you'll probably have a regulator rectifier (for example, a Harley voltage regulator rectifier). The numbers are not important. problems like causing the bike to run poorly and miss. The longer it goes without trouble, the more likely it is to fail. The 4 Main Reasons. Damaged solenoids the opposite problem of your vehicles starter not stopping, is a failure to start. Another important thing to check periodically is that the starter mounting bolts are properly tightened.

You could also attempt to do it yourself, but this is quite a technical job. Does A Motorcycle Coil Have To Be Grounded? Eventually the buildup can interrupt the flow of electricity and prevent the starter motor from working. A bad stator can cause a host of problems with your ignition system, creating no spark. Unfortunately, the starter motor lives a pretty tough life, so its not surprising that it fails from time to time. The solenoid has two wires that normally connect to the starter button. As the engine starts, engage the throttle to give the engine more gas, and you should be off and running. If that checks out, you can then measure the resistance between the secondary wire (plug wire), w hich A new stator can cost around $300-$400 some for vintage or hard to find motorcycles can even end up as much as $1,500. Get down to the garage quickly or risk the loss of both parts. If you catch a failing starter soon enough, you may not have to replace it and could potentially just repair it instead.
