Hey Chuck, I don't have a real answer for you,..but a diagram would be very helpful I would think,..although I'm sure Marcus explained it well,..it is hard to compute what he's saying and put it into a "diagram" in your head. I like pictures, Ha,Ha,...

Hi Jeff, ya, Marcus sent me a cleared explanation and a diagram and now I'm sure I can do it right!
Marcus really put some time into helping me and I appreciate what a nice guy he is!

 So Chuck, are you planning to run your 12 volt pump so it runs all the time

THANKS!

Marcus spent considerable time showing me how to set mine up, even sent me a diagram. I guess I'm just plain stupid?

I tried and failed so far!

I do have the continuous solenoid though!

Chuck my friend, you should have told me that you did not understand.  Being a former electrical engineer sometimes I take things for granted that others do not understand.I am going to show what I sent you one more time so everyone knows how.  I will try to field questions but the season has already started and we are busy working.

The line #s below correspond with the wire numbers in the attached electrical layout.

1. 10 gauge red wire from battery +12 V to one end of 40 amp circuit breaker (CB).
2. 10 gauge red wire from other end of circuit breaker to a switch.
3. 10 gauge red wire from other end of switch to input of solenoid.
4. 12 gauge red wire from input of solenoid to one end of delavan pressure switch wire.
5. 12 gauge black wire from other end of delavan pressure switch wire to solenoid's coil +12 V terminal.    (In the past Chuck, I accidentally said red)...
     ( some solenoids show a positive and some do not care.)
6. 10 gauge red wire from Delavan +12V wire (red) to output of solenoid.
7. 10 gauge black wire from battery -12 V to solenoid's coil  -12 V terminal.
8. 10 gauge black wire from battery -12 V to Delavan ground wire (black) to output of solenoid.

Chuck, from what I understand you are concerned about burning the pump or solenoid.  The power wires on the delavan are on the opposite end of the pump from where the in/out pump ports are.  Wire 6 coming from the Delavan is red & wire 8 coming from the Delavan is black.  The pressure switch wires are on the end of the pump where the in/out pump ports are.  It does not matter which wire you use because it is not polarized.  It is only a switch.  You could use the black wire from the Delavan pressure switch for wire 5.

A solenoid is just a large switch.  When you apply 12 volts to the small posts it turns the solenoid switch on and power can flow from one large post to the other.  Usually it does not matter which wire (+ or -) goes to either of the 2 small posts.  Likewise it usually does not matter which wire (+ or -) goes to either of the 2 large posts.

To experiment and prove my point, hook one wire about a foot long to the first small post.  Then hook another wire about a foot long to the 2nd small post.  Then touch the end of the wires (with about 1/4" of insulation removed) to a battery.  The solenoid should click.  That is the solenoid closing the internal switch between the 2 large posts.  If it does not click then reverse the leads from the small posts to the battery and tr again.  Most solenoids are non polarized which means you can hook the battery to either small post and the solenoid will still turn on.

Thank you Marcus. I didn't want to keep bothering you.

You explained it in such a way, that only a dummy could NOT figure it out!

Now, with this further explanation, I believe I can do it!

Thanks again!

I really appreciate it!

Chuck, we have known each other through RCIA for a long time and have seen a lot of members come and go.  If you ever have a problem email me.  If I am busy I will respond when I can.  In another month I will be swamped thank goodness so try to get it running now while I am slow.   If you have to many problems with the Delavan Fatboy go with a FJR7300132A  FloJet Pentaflex Pump, 12 Volt, Viton    qty  1 @ 349.50 ea from Dultmeier.com.  It is a much better built 12 volt pump.  I wish you luck!
