Question about Yamaha XJ 650 Motorcycles
Posted by Anonymous on
Hi, Anonymous before diagnosing any brake light issue always check the bulb and fuse first for integrity a brake light staying on is usually caused by the front brake light switch, which is mechanical, not disengaging. On early models moving the throttle control housing closer to the front brake master cylinder is the main fix. On late models, the switch gets tweaked and needs to be realigned. A brake light that does not come on when the brake lever is applied can be caused by a faulty switch or no continuity in the wiring at the switch. The rear brake light switch is hydraulic and it is extremely rare to malfunction in a closed circuit condition causing the brake light to stay on. Usually, rear brake light switch issues are caused by no brake pedal free play or a sticky rear master cylinder piston. A brake light that does not come on when the rear brake pedal is depressed can be caused by a faulty switch, air contamination in the brake line, or no continuity in the wiring at the switch.

Change oil and, filters regularly; lube the throttle cables and, all moving parts drain the fuel tank and, replace the fuel filter every year, or; when needed. never leave fuel in the bike when you store it without using "stabil" only check your ignition with a timing light get a maintenance schedule from the bike's manufacturer and, follow it.

SOURCE: Yamaha 650 Maxim Won't Turnover
Make sure the battery is fully charged and the battery connections are free of corrosion and tight. A fully charged 12 volt battery should read at least 13.25 volts. Also check the fuses, making sure each one is not 'blown' and is making proper electrical contact in the fuse box.
If the above items are correct but it still won't crank over with the electric starter, locate the starter solenoid and - using a large screwdriver - carefully touch it across the two large cable connections on the top. If the starter spins over, then you've got a bad starter solenoid. If you've got voltage to the top of the solenoid and the starter still doesn't spin, then you've got either a bad starter motor or a bad electrical connection going to it.

Testimonial: "I did the screwdriver trick and it started to turnover (I've probably got a dead/dying battery too) and it looks like its the solenoid. Thanks!"
