I have an 1977 Yamaha XS360 that is having starting issues. First off I want to say that the solenoid is not clicking. So here is what I did, I jumpered across the larger terminals and got the starter motor to move. This told me that the solenoid was faulty! Well, maybe. I measured the voltage getting to the smaller wires on the solenoid (the coil) . I am only getting 10 volts, but my battery reads 12.6 volts. So, I jumped from the battery to the smaller hot side of the coil and the solenoid is engaging!!! Am I not getting enough current to the coil? Is this why the solenoid wont switch? Can some one help me please! Thanks!
