Should you find your battery to be weak, it would be advisable that you get a better one and use it to test starting problems. It does not matter which big terminal you connect the wire to since starter relays do not have polarity. With a new relay, you are assured of a problem that is solved once and for all. Because the fuse box contains may different fuses and relays, it may be difficult to single out the starter relay. They are: The starting process fails completely. It is part of a vehicle’s regular maintenance practices. Connect the multimeter to the secondary side of the relay. 260. Yamaha Majesty YP250 starter motors can be made to fit by swapping the rear mounting case from the old TTR starter over to the Majesty starter. The problems comes when the wire corrodes at the ends where the wires plug into something. Typically, expect a starter relay to last more than 100 miles. The magnetic field keeps on failing, so the solenoid spring keeps on snapping back. The starter relay in a motorcycle enables power to flow from the battery to the motor when you start your motorcycle. We will come to the solutions once we know the symptoms of a failed starter relay. If the relay is corroded or dirt, cleaning the connections can restore the flow of current. In the next part of this guide, we examine this starter system component in detail; how it looks like and its internal construction. To confirm the problem to be the relay, you would need to test the battery’s operation by switching on the car accessories. Starter Relay: This is part of the electric system that provides current to the starter, sometimes a failure of this component can stop the starter from working, if you hear just a “tick” noise from the starter every time you press the starter button, it may be either because of a low battery or a failing starter relay. The other big posts are the starter circuit terminals. Some relays will only have one small post. Most of the time, cleaning the external parts works fine. It would also be expensive to make automobiles with big ignition switches and corresponding wire sizes.
