-When the control's orange lock light is on there
should be 3 to 5 VDC between pins 2 and 5 at TS 1.
-There should always be a supply voltage of
25 to 33 VDC between pins 1 and 5 at TS 1.

After about a second the voltage will drop
to about 30% of the supply voltage between pins
1 and 2 of TS2 .
-When the solenoid initially energizes there
should be 25 to 33 VDC at TS2.
