Hi there!

I guess you know how to work with a multimeter ? If so check whether the wire between the solenoid and the starter is ok.

It sometimes happens (been there, done that) that due to a faulty solenoid, there's not enough juice coming through and one of the windings on the starter burns out. If that happens you're down sh*tcreek.

That said, if you attach a set of jump leads to the bike, black (-) goes to the frame and red (+) directly to the bolt, where the cable of the solenoid is screwed in, the starter should spin. It will not engage, because the solenoid also pushes the starter sprocket in gear with the starter ring on the crankshaft, but this doesn't matter because it is just to proof that the starter is still working.

That said, even new solenoids can be broken.

If you have a XV1000/TR1/XV920R, you may use the solenoid of an Suzuki LJ80/SJ413 (or other Suzukis with the same solenoid, IIRC the Swift was also among those), because they're a lot cheaper than the OEM Yamaha part.

To sum it up:
(always assuming that you have check ALL THE connectors beforehand and have cleaned them and greased them with some di-electric grease)

check the starter, if it doesn't work -> new starter
if it does work -> new solenoid (it's only around 10GBP new, you probably can get it for a quid at the breaker's)
if it still doesn't work -> check the battery again, probably it is too weak, even though it is freshly charged!

Cheers,
Greg

Hello,
i had a similar problem with my Tr and lately with the bike of a friend. The solenoid did not work.
In both cases the startermotor causes the problem. It seems, that the solenoid needs the power (magnetic field?) of the starter to have a correct funktion. I can´t explain why this is so-may be an elektrician can. In my case i bought a new starter, which not only solved the problem, it just works much better now.
