1982 GS750EZ won't start

[Spaceman_Bob]

So I just picked up a 1982 Suzuki GS750E a few weeks ago. It had been working fine until the other day, when it refused to start.
I'm new to motorcycles but have a decent idea of how they work.

Here are the things I know/have tested so far:

All switches, clutch lever, gears, etc. are in the correct position - when I push the starter button I hear the solenoid click and nothing else happens.
Tried jumping off another bike, same thing.
Took my battery out of the bike and connected jumper cables to a car battery and to the battery leads in the bike, same thing (lights, etc. lit up so I know the bike was getting power).
In this same configuration, connected the + jumper cable directly to the opposite end of the solenoid in an attempt to bypass it, and heard no sound at all, starter motor didn't move.
The bike will push start, I rode it about 10 miles home, worked completely fine, so it can't be anything wrong with the engine itself.

So it seems I have a problem somewhere in the starter cable or starter motor itself. Does that sound correct?
If so, what steps can I take from here to figure out exactly where my problem is and how to fix it?

Thanks in advance!

Sounds like the starter motor gave it up. Pull it out and disassemble. You may be able to clean the armature and get it back in working order.

since you can pop start it, i'd think the starter or starter solenoid is stuck, as you say. i'd swap out that starter solenoid for a known good one and try or maybe you could pull the starter cover and tap it with a wood block and hammer, and see if is will regain conciousness? worse case you can remove the seat, tank, airbox, carbs and pull the starter and see if it responds to power

it sounds to me like you what you are looking for already...

When you connect the battery directly to the starter, can you hear current moving through the starter, or can you use an ammeter to see if current is moving through it (and how much). If very low current (< 1a) or no current this could mean broken wires or worn burshes in the armerature of the starter... a high current would mean the started is jammed, possibly by dirt.. a very very high current > 60a and hot wires would mean that you have a short somewhere in the starter diconnect the battery and fix!

Good luck.
