1. Remove 3 screws from back — install two D cell batteries.
2. Adjust probe spacing by loosening screws on terminal block and re-tightening (Caution: do not
over-tighten).
3. Rotate rheostat COMPLETELY to counter clockwise position—turn switch on. Failure to do this will
peg out needle, and cause the tester to no longer function, which will void your warranty.
4. Position probes on commutator bars; turn rheostat clockwise until meter hand indicates OK (Fig. 1).
5. Systematically check all commutator bars.

BAR TO BAR TESTER MODEL 101
The only low cost tester that assures product stability. A simple check takes less than 30 seconds and
eliminates those troublesome comebacks and many dollars of additional expense.
Note: Be sure and read instructions in brochure that comes with your Bar to Bar Tester.
FEATURES:
I. The #101 will clearly show an open or partial open in the armature winding. Many times, solder
loosening, slung out, or damaged connections have occurred within the armature and are not visible
to the naked eye. Most often, growler testing will not show any of these faults. With a black or open
indication on the #101's meter, simply follow the red probe to the exact location of problem on the
armature. At this point the armature can be resoldered, saving a rewind replacement or costly war-
ranty.
II. The #101 will immediately pinpoint a reverse coil by indicating yellow or reverse on the meter.
III. The #101 quickly locates a short by pointing the red or short .
IV. The #101 will further show a good, re-usable armature by continually reading in the green or ok.
The Model #101 is the fastest, simplest, most time saving device of it’s kind. The test and results are
100% accurate. It offers at minimal cost both time and equipment savings, and quality that assures a
long and dependable life.
ADDITIONAL INSTRUCTIONS:
I. This meter will check any armature that has enough resistance to move the meter hand into the
green. On a large armature which has very little resistance the meter hand will move only slightly into
the green, which is alright, all we are looking for is a point to get a pattern all the way around the com-
mutator.
II. A dead short will keep the hand of the meter in the red. A partial short will not let the hand come
back to the red position, but will show a lower reading in the green from where you had your rheostat
set for a pattern to go by. This will show you where your problem is by following the red probe to the
lead in your armature coil.
III. If you use a growler on your armature and it shows shorted all the way around. It is very possible
that you have an armature with an equalizer. Be sure to use the Bar to Bar Tester and set your meter
