How to check coil

Should have 4 wires. Two for 12v DC and the other two are the switch. What are you trying to troubleshoot?

Put 12 volts to the small terminals and check for continuity between the 2 large ones.

Or, if it clunks but don't do what it should, jump the 2 big posts and see if it does what it should.

The chassis batteries are not being charged while on shore power. I'm thinking it's the coil. I'm getting DC power from three of the four posts on the coil. Could the post with no power be the one going to the chassis batteries? The coach batteries are being charged while on shore power. Thanks for your help.

Since 1 post is ground you will only get power on 3.

What you need to check, is the amount of voltage at each big post while power is on 1 small one.

A charging battery will be 13.5 volts or more. A sitting battery is 12.6 or so.

When the relay is working you should see the same voltage on both big posts.

Methinks the flyboytravel is trying to troubleshoot the operation of a White-Rodgers 586-105-105111-3 solenoid.

A picture may help what others have already said. These are notorious for failing and easy to change. Once you install a new one, tear the old one apart to inspect and you will see the issue.

Are you sure that it is supposed to charge the chassis batteries while on shore power?
My Holiday Rambler is equipped with an Isolator Relay Delay, and it only charges the house batteries when on shore power.

Some motorhomes have a bi-directional isolator relay delay, and it will charge both sets of batteries when on shore power.

Of course, you could have some other type of device than what I've referenced.
