Check to be sure the Salesman Switch (inside, by the entry door) is turned ON.  It should be, if you have power to all the small breakers.
Yes it is on, I have lights on in here and radio going and fridge but I turned it off and back on to make sure.

OK

You have START battery voltage at the big round 90A circuit breaker under the white cover.

You do not have START battery voltage at either LARGE post on the ignition solenoid.

My schematic shows one large (430 4RD) red cable going from the 90A circuit breaker directly (uninterrupted) to ignition solenoid.

Unless Brett or someone else can come up with another idea...

The only logical explanation is a break in the cable from the circuit breaker to the ignition solenoid.

Sounds reasonable, that is what my diagram B-2126 shows.

does that big red wire run down the center tunnel?

That would be my guess, although I have never tried to trace it out.

Still...a broken 4 gauge cable seems so unlikely, unless other work was recently done around it, or you had a GIANT RAT invasion or something.

Even is this (broken cable) is the problem, I am still puzzled by the voltage readings you get (see Reply #30) at the ignition solenoid with boost switch turned ON.  Can't figure out how voltage is getting to the ignition solenoid.

Somebody smarter than me needs to step up with a brilliant idea.    :help:

I think I have just figured that out, its called check as many grounds as you can reach.  I had been using different spots on the frame around the front dash panel, so I got to looking at it and thought try the bolts that go through the frame to attach it.  guess what I can how 12+v coming into the solenoid that way and repeated 5 times to make sure.  I thought i was pushing hard enough to get through the paint as it started bending the probe on my multi-meter.

so with that it looks like I am back to that solenoid.  with key off or on I have voltage to the big wire but nothing to the other big post.

How about the small posts on the ignition solenoid?  Do you get voltage to one of the small posts with ignition key ON?

Yes with key on the post with white wires has 12+v the green (ground)  no voltage.
doesnt that mean the switch on the inside the solenoid is not working when the switch sends 12V?

EXCELLENT!  You have now (finally) narrowed the problem down to a faulty ignition solenoid!

Yes, like any solenoid - power to small wire energizes coil - coil pulls the contacts to the "closed" position - current flows through the large posts.

Either the coil is burned out, or the contacts are not moving, or the contacts are corroded to where they don't pass the current.

Steve,

SMACK IT (light, sharp rap with handle of screwdriver).  MAY temporarily "wake it up".

And, for work around, as I posted above, you can mark and move wires from one large lug and add them to the wires on the other large lug.

Another easy test (do NOT drive like this) is to take a 10 gauge or so wire and go from large lug to large lug.  Everything should work.

For replacement, I am a BIG fan of the Blue sea 9012

Thanks Brett, I tired that but it did no good,
I have another one, that is what I was waiting on yesterday from amazon

what is this little thing, a diode?  what does it do?

Leave the diode, it prevents voltage spike with out-rush when circuit is opened.

And, you have verified that it is a CONSTANT DUTY solenoid rated for at least 50 and preferably 100 amps continuous?

a word of caution, the new solenoid did not come with the nuts to hold the wires and the ones from my old one are different thread.

you will be able to get a turn or so and with your bundle of wires behind it you think it is just hard to turn because of that, WRONG.  go get some new nuts that fit the new solenoid.  just my $80 worth of advice.

In your photo, that black solenoid (with the diode) is not the Cole Hersee 24213.  Where did you get it?

The Cole Hersee 24213 is a silver metal solenoid, and comes with nuts and washers.

the new one is silver but it did not come with nuts and washers,  I think I fixed the threads enough that with proper nuts it will tighten down ok.  off to town to get some nuts "LOL"

I suspect you did not get a genuine Cole Hersee solenoid, or you got a "open box" unit that was missing the hardware.

Does it say "COLE HERSEE" on the top cover?

OK - just kinda strange they did not send the nuts and washers.  No big deal, as long as you got it taken care of.

I'd knock points off the seller feedback for shorting you on the parts.

The boxed version for $2 more comes with nuts and washers.  What you bought was the bulk package, which does not come with washers and nuts.  Yea, you got it fixed.
