Larry,

Sure you will do it but all of us should not forget to disconnect the engine battery (or house, depending) before changing out any solenoids.

The owner of the largest FBO at our airport was working on the back seat of a big twin when he shorted something. Tried to put it out but failing, tried to get out, stumbled and hit his head on the concrete floor. The twin burned up taking Leo, the hanger, along with two other big twins. I had lunch with him a couple of days before. How quickly things can happen.

After you replace the solenoid, you might take the old one apart and file the contacts.  Ten minute job and you'll have a spare jic.

...but don't use an emery board (sandpaper) fingernail file because it'll form a glass like silica coating on the contacts when they heat up ...at least it does on high voltage AC relays almost every time, so I use a tiny breaker point file made for engine ignition systems.

Still fighting this project.  I've installed a new Cole-Hersee solenoid, and now I get nothing when I turn the key on.  There's juice to the battery side, all the wires are accounted for, and I suspect the ignition switch - which had been a little finicky in recent months.  If I could get the plug off the back of the sucker I could test continuity, but there are a couple of tabs that thrwart removal of the plug.  Any suggestions?

Yes.  Go to the small terminal on the ignition solenoid.  When you turn on the key, you should see 12 VDC at the small terminal.  If you have two small terminals, one is ground, the other the one from the ignition switch (If only one small terminal, the solenoid grounds through the body of the solenoid.

Check it two ways-- see if there is 12 VDC from the ignition switch.  Take a small jumper wire from battery side large lug to the positive small signal terminal (with the wire from ignition switch removed).

Thank you, Brett - I did get 12v at either small terminal with the key on.  I have both the red and blue wires on a single small terminal of the solenoid, but both terminals seem to work the same.  I didn't run the second check yet, as I am a little uncertain of the process.

Not sure I understand.  If the small signal terminal has 12 VDC, the other large lug should also have 12 VDC and all "ignition on" things should work.

That's what I'd have thought too.  But... battery side hot, both small lugs hot with switch on, and large lug with red wires no voltage at all.

Make  sure the solenoid is grounded.  Some ground through the body (so if not mounted on chassis metal, you will run a small wire from the bolt holding down the solenoid to the ground terminal panel).  If two small terminal, one should go to ground, the other to ignition.

I'm getting .07 ohms from the body of the solenoid to ground, so that seems to be OK.  Both small lugs show 12vdc only when the ignition is on - I don't think either one is a ground, and the solenoid appears to be designed to ground through the body.

Okay, it's beginning to dawn on me, but let me run it by you first.  The second small terminal - which shows 12vdc with the ignition switch ON - should be grounded?  If so I could run a wire from the terminal to ground and everything should be OK?

Larry,

If you have the Cole-Hersee 24213, Brett has it exactly correct. Ground either one of the small terminals and connect the other to the wire to +12V from the ignition switch when you turn the key on. Can't go wrong here.

Reading your last post, yes, bring a ground wire up to the empty small terminal.

Ahhh... that sound you hear is an old Detroit Diesel turning over just like it's supposed to.  Oh, and me, breathing a huge sigh of relief and gratitude.  Wife Carol asked - how do your Forum friends get back to you so quickly?  I'm asking the same thing, and once again I'm indebted to you who know your stuff so well.  Kudos especially to Brett, and thanks to all.
