Exclamation Diag Sv650 Starter Motor/Relay

Hi guys, I have been diagnosing a starting issue with my sv650 and the starter motor appears to be the issue, I still need to do a continuity test on the relay but im 50% sure its just fine.

A poster suggested that I bench the starter motor before buying a new one just to be sure but im not sure how that would help, as the diag procedure appears to be the same (run a lead from the [bendix?] positive terminal on starter motor to the positive terminal on battery) and Im not getting any movement from the starter motor.

has anyone done one of these before and can explain why benching it would be any different than an on bike diag?

Also, is the solenoid the same as the relay? I cannot find the solenoid on the starter itself nor anywhere between where the relay wires run down to the starter

The solenoid is the same as the relay.
A quick and dirty test is to take a screwdriver and put it between the 2 main leads on the solenoid and see if the bike turns over.
Only do it for a second or two and then pull the screwdriver off the terminals.
Make sure there's nothing flammable around and that the bike is in neutral.
It's a shame I have to add this, but in this day and age of no personal responsibility, do it at your own risk.

Thanks, I meant to add that i actually took my knife on my leatherman and tried to bridge the two terminals, and I got nothing, I was assuming that was some sort of fail-safe (as it shouldnt be that easy to shock yourself :P) but, now that Im reading more into this, is it possible that if I bridge the two leads and I get no crank that both the starter motor AND the solenoid are bad?

Oh, i meant to add that I got no movement from the starter when running the lead from the positive terminal to the starter motor's terminal but when i accidentally touched the starter housing i did get a spark maybe thats not of any help but i just thought i'd add it.

You got a spark because you touched the positive lead to the starter case which is grounded.

hey man just wanted to follow up thanks for the info about the different parts of the starting system, i ended up benching my starter and found that it was operational but too weak to start the bike so i swapped a used one in,

everythings all good now.

going to do a voltage drop test on the RR sense that is usually gone long before the starter on these bikes and will prob be the next to go.
