Got ready to leave this morning and when I turned the key no alarms and no light on the dash except the wait to travel light.
I had read about the ignition relay on line to grabbed my meter and went out to check it. Sure enough it was clicking in but no voltage was being past through the relay. Had my wife cycle the switch and after a slight delay everything appeared normal. So we drove to Speedco for a LOF. I shut down several times and it worked 8 out of 10 times.
So we are in Howe, IN and move to Goshen on Friday. I am hopping some one has a part number and I can go to NAPA or another parts store and pick one up and change it while I am here. I understand it is a 85A continuous duty 12V solenoid. So if you have a part number please send it along. I can not read the number on this one. Thanks

Bob,
Nothing special here if you take the old one in they should be able to match it up. Anything rated continuous duty and 85amp or better, normally open, 12V coil will work just fine. A Cole Hersee 24059 or a 24115 look like a good reference number for an 85 amp continuous duty, normally open, 12V coil solenoid.

Bob,
Any reasonably sized RV parts store will have the solenoid in stock. These solenoids are very common in the RV industry because they are used as battery isolators on many class C motorhomes, but they are not common in the automotive industry (Napa). Most places charge between $25 and $30 for the solenoid.

Bob,
Gerald is right, it may not be a stock item in an auto parts store but both Napa and O Reilly list it and can probably have it within a day if an RV place does not stock it that is near you. The other possible choice is electric golf carts use these type of solenoids and may also stock one that will work.

This is an item that you want to replace as soon as possible, your contacts are probably burned or pitted and making very marginal contact. This solenoid can fail or generate an open contact while driving and shut down the engine. It is a safety issue for sure. I would change it before driving again personally.

Wasn't there a thread here awhile back about replacing this solenoid with an electronic one? Or is my memory as bad as feared?

Joel,
Yes there is a solid state replacement. However it is not same form factor so a cable or 2 need to be modified.

Stopped by NAPA and picked up an ST85 solenoid for $43.00. It has good reviews on line in the golf cart, Jeep, and even the RV community. Opened up the old one and it was corroded and pitted. We are back in business now.
Thanks for all the help.

Thanks Steve-
My ignition acted up once in super high temp and humidity. I have a hunch it's contacts aren't beautiful anymore -been there done that with several "Ford" style solenoids over the decades. One of these days it will need replacing, and the solid state is more reliable.

Watch eBay. I got mine for $39. Right now they are $200+ on eBay and Amazon.

I keep one of these solenoids with me at all times. A small investment to ensure I don't get stuck somewhere I don't want to be. NAPA has two versions; one has internal copper parts and the other, a bit more excpensive, has silver internal parts. A long time ago, when Beaver was in production, I was told by the folks in the know to get the silver one since it would last longer.

I found the Cole Hersee 24059 at Amazon for $8.75! Could it be the right one?

Bill,
That one will work. In fact that is the solenoid that I care as a spare.

At less than $9, I ordered two. Someday I might get a hero award at a rally when I can say, "I've got a spare I can give you!"
-
Good find I think I will order a spare. If were were here longer I could have had one shaped here.
-
I just bought one from Amazon as a spare and I figured I'd take a better look at the one that's in there now. I noticed that there's what appears to be a diode across the primary (low current) terminals. Does anyone know why it is there?
-
This post covers the reason for the diode.

Your link doesn't work but this one does: http://forum.bacrallies.com/m-1372964522/s-11/highlight-solenoid+diode/#num11
Thanks

Joel the solenoid has a coil it it to operate the contacts. When you take away the 12V the current tries to reverse due to inductive kick. The diode shorts or shunts it so that it does not feed back into the circuit.
Thats exactly what an ignition coil does to make a spark plug work on a larger scale, and it does not have the diode to stop it.

Thanks Joel for fixing the link.....sometimes cut and paste works and sometimes it has a mind of its own.
