Comments/Questions: Bob,
I'm using the Z16. I have a White-Rodgers 70-111226 5 Coil 12vDC cont
battery relay. Will this work? I guess the real question is, does the
White-Rodgers relay have the spike supression diode that is shown in the
schematic? Am I making sense?

Very few contactors come with the diode installed.
The S702-1 starter contactor from B&C is one example.
The S701 series (Stancor/White-Rogers) does not.
Photos on my website like:

Illustrate how the diodes are installed externally for
various applications. Yes, the contactor you've cited
is suitable to the task of battery master relay in
Figure z-16
I will invite you to join us on the AeroElectric List
to continue this and similar discussions. It's useful to
share the information with as many folks as possible.
A further benefit can be realized with membership on
the list. There are lots of technically capable folks
on the list who can offer suggestions too. You can
