Hello Theresa Honeycutt,
There is an easily explainable configuration that would cause your dilemma on
OLD FASHION 4 connection (two big posts & two small gauge wire posts) starter SOLENOIDS...
1997 Tercel is 3 wire (can't happen)
Technically what you are describing is not possible as a USER MISTAKE because the TOYOTA solenoid only has THREE Battery TERMINALS showing.
It is a
MANUFACTURING DEFECT.
YOU will need to return the starter as
DEFECTIVE and get another one..
Fault: The primary winding of the ("s" lead on classic drawings ... "st1" lead on the 1997 Tercel) has a
DIRECT SHORT to the output battery (starter motor side) of the main battery source (internal solenoid defect).
There should be
ABSOLUTELY no continuity between the large posts (battery & motor) and the ST1 terminal WITHOUT THE STARTER switch ("st1") momentary contact being energized.
Then inspect the Ring gear on the vehicle to assure no
GEAR TEETH have been broken off in the previous melee... (Serious job...
hope not).
