"G07-9", "G07-20" and "G07-21" respectively with select
lever shifted to each range.
Taking terminal "G07-21" as an example, is battery
voltage will be indicated only when select lever is shifted
to "2" range and 0 V for other ranges as shown in table.
Check voltage at other terminals likewise, referring to
