electrical probs

[Tim2005]

On Yamaha XJ750 Seca (1981)

A year ago i had probs with power cutting on and off while riding, then i eventually lost all power, no dash lights , nothing . The bike sat in my garage for a winter, and now im messin with it again. i charged the batt. When i turn the key i get lights for the speedo and tach, also the tail light is on. nothing eltse turns on. bike dosent turn over , no horn , blinkers, anything. when the bike was running , when i turn the key , along with the speedo and tach being lit up , the warning light turns on , and the LCD screen is lit with other indicators. checked the fuses , they are fine. any advice would be helpfull as i dont know much about bikes.

If all the fuses turn out good especially the main fuse then you might want to check your starter solenoid.

Try jumping the two leads on the solenoid if the bike starts then most likely the solenoid is bad.

If it doesn't start then it could be two other things.

1- your Ignitions might be shoot. tell tail signs. Bike cutting out during the ride and bike loses power when you hit the starter button but power returns when you turn the key off then back on.

2- The Rectifier might be gone. The rectifier will cause many different problem that might have you chasing carb problems, to the bike won't start at all with no cranking

If you wont to learn how to check your rectifier this guy explains it best.
