Marquette Growler

Does anybody have the instruction manual for a Model 41-107 Marquette Growler? or could someone let me know how to use this boat anchor?
Thanks

tie a rope around it and when you get to the spot in the lake you want to park you throw it overboard. Manuals for boat anchors geess.....!

What do I do if da rope is too short?

Any old manual with a starter or generator section will have basic directions.

An internet search will also turn some up

Place the armature in the growler and turn it on.

With a spare hacksaw blade, place it lengthwise on the top of the armature on one of the segments.

Rotate the armature until you've tested all of the metal segments.

If the blade sticks at any point due to a magnetic pull, the armature is shorted.

Well, don't wrap it around your leg!

Growlers were used before mechanics turned into parts changers.I still use one in my shop.

?? The hacksaw blade SHOULD be attracted when the armature is good - not bad. If the blade starts to vibrate and "growls", then it's bad. I suppose that's why it's called a "growler."

That is unless you've got some strange machine I've never seen before. I've got three old growlers I use now an then.

Most have two test leads also. When touching two commutator bars with the leads - the test light should not come on if good.

When holding the hacksaw blade near the armature- when good magnetism pulls on it smoothly. When bad it vibrates, shudders, hums - i.e. "growls."

I've got a Marquette and two Allens. All work pretty much the same. Here's instructions.

Here's my Allen with probes:

Growler instructions in text:

ARMATURE TEST.- There are two practical tests for locating shorts, opens, and grounds in armatures- the growler test and the bar-to-bar test.
To test for short circuits, place the armature on the V-block of the growler and turn on the current. With a thin metal strip (hacksaw blade is good) held over the core, as shown in figure 2-17, rotate the armature slowly through a complete revolution. If a short is present, the steel strip will become magnetized and vibrate. To find out whether the armature coils of the commutator are short-circuited, clean between the commutator segments and repeat the test. Should the thin metal strip still vibrate, the armature is short-circuited internally and must be replaced.
Not all armatures can be tested for short circuits by the method just described. These armatures can be identified by excessive vibration of the saw blade all around the armature during the test. With these armatures, test for short circuits by using the milliampere contacts on an ac millimeter, as shown in figure 2-18. In doing so, keep the armature stationary in the V-block and move the contacts around the commutator until the highest reading is obtained. Then turn the armature to bring each pair of segments under the contacts and read the milliammeter at the same time. The readings should be nearly the same for each pair of adjacent bars. If a coil is short-circuited, the milliammeter reading will drop to almost zero.
Test the armature for grounds by using the test light circuit, which is a part of most modern factory-built growlers (fig. 2-19). Place the armature on the V-block and touch one of the test probes to the armature core iron. Touch the other probe to each commutator segment in turn. If the armature is grounded, the bulb in the base of the growler will light. In contacting armature surfaces with the test probes, do not touch the bearing or the brush surfaces of the commutator. The arc would burn or pit the smooth finish. Replace the armature if it is grounded.
In testing individual armature coils for open circuits, use the test probes, as shown in figure 2-20. Place them on the riser part of adjacent commutator bars, not on the brush surfaces. If the test lamp does not light, there is a break some where in the coil. Repeat this test on every pair of adjacent bars. Do this by walking the probes from bar to bar. Should you find an open coil, the fault may be at the commutator connectors where it is possible to make repairs with a little solder. If a coil is open-circuited internally, the armature should be discarded

Here's my other big electric magnet- my magnet charger for magnetos :

Did I get it backwards?

Last time I used one was 1968.

Wow, just a little envious of the magneto charger, (lol) would like to have one like that. I have three magneto test machines but in need of a charger.

I got lucky and bought out the entire contents of a magneto shop for $200. All the tools and inventory of Wico and Fairbanks-Morse parts. Two chargers, three testers, etc. Also a bunch of new Wisconsin engine parts. The new owners of the building were going to take all of the stuff down to the scrapyard.

The charger originally did not have modern rectifiers in it. It has what look like screw-in light bulbs that did the job. But they got replaced with a modern rectifier upgrade.

If you look on a site called etestmanuals.com they should have a listing for the model
41-107 growler. But if you have a motor manual called” auto engines and electrical
systems”,(from early 1970's or earlier) it has a chapter on generators/starters and will
explain in pretty good detail how to use this tool.

There is a good Utube video of the U.S. Navy doing that. The chain was around twelve inch. ALL Gone.

Allan, I think you got it right. Your description is the same way I was taught in auto mechanics. 'Course that was in 1970. Ain't used one since.
