Testing solenoid
Can someone please confirm if I am following the proper procedure for doing a bench test of the solenoid on my Onan 4KYK generator? I applied 12 volt dc power to the large post that comes from the bat...

Here's Test from the 4KY Service Manual

A check can be made by measuring the resistance of coil terminals I and S (Figure 6-5). With the harness leads removed, the coil should read 3–5 ohms.
If an abnormal reading is measured, replace start solenoid relay K1.
If the coil checks good and a problem with the solenoid is still suspected, remove the leads from the side terminal posts.
An open circuit should be measured between the side terminal posts with the coil de-energized. With 12 VDC applied across the coil
(I and S terminals) the relay should be energized and continuity should be measured between the side posts.

This means you need Battery AND Ground on those two little spade terminals before the Coil will pull in and connect the two Stud Terminals.
