Bosch relay question.

[toddad538]

I have a question regarding a Bosch 5 terminal relay.

I have continuity between terminals 30 and 87A.
I don't have continuity between terminals 30 and 87.
I understand that when the coil on terminals 85 and 86 is energized
the continuity between 30 and 87a will go away and I will have
continuity between 30 and 87.

Just for fun I tried checking for continuity between terminals 85
and 86 and there is none.

Question:
If I don't have continuity between 85 and 86 how does the coil
become energized.

I would think that there must be continuity between 85 and 86 to
complete the circuit thus energizing the coil.

Thanks for your time.
