I have 30a 2 element setup that seems to be losing power at the contactor when I flip my 3 way switch to select that element. I have 2 aubrins 2362 pids each with its on 40a ssr and contactor. When I turn the main power on to the box, I have 240v on the imput side of the contactors with no power on the out put side. ( correct ). When I turn my 3 way switch to select an element I check the power at the contactor and only get 50v on the imput and 50 v onthe output side . I checked my ssr when I checked my contactor and only had 200v on the output side of the ssr. What am I doing wrong, I used P-J 30a 2 elememt 2 pump estop diagragm for wiring and I believe its wired per the diagragm.

Pic lay out

Power plug in top left corner wired to din rail into 25a/15a breakers, under power plug is element 1 plug with contactor wired to ssr 1, under that is element pkug 2 with contactor wired to ssr2. Pump plugs are out of sight.

Sorry same pic posted 3 times.

I pulled the indicater lights and now im getting full power to the out put side on the contactor. How I I still use the indicator lights and still get the power to the plugs that required?
 
I can only speak to my recent experience with 110v indicators...
I was seeing this very same phenomenon when I wired the indicators in series with the contactor coil... I was only seeing 38v at the hot side of the contactor (after it went thru the indicator)
I solved it by running separate dedicated indicator and contactor wires from the switch

How you solve, I have no idea :(
 
Both my indicator lights are 220v but they are giving problems unless I unplug them
 
Well I ran dedicated lines for each light through the 3-way switch and it has solved my problem.
 
The indicator lights should be wired in parallel with the load. It sounds like you had them in series with the load (contactors & SSRs) which prevented the load from being energized.
