Will it growl?

Narrated: Antique Armature Testing Growler [Restoration]

Comments

I once worked in a small automotive electrical rebuilding shop where I used one of these beasts daily. The fact that I’m still here to tell you about it demonstrates that you were right about the lightbulb limiting the current in the test probe circuit but it still made a nasty little arc every time there was a complete circuit. We kept a pair of insulated rubber gloves right next to the thing and I always used them.

Sweet. Was thinking about you. Excited to see

Brendan Hood

I've used one of these exact tools. In fact, depending on where you acquired this one, it may actually be the same one... (cue creepy music). My Great Uncle owned a Water Well Drilling/Servicing company in North Battleford. I used to work for him doing servicing, shop work, etc... One of the things we did was rebuilding pump motors, and part of the general process involved, you guessed it, armature testing. My uncle wasn't one for new and fancy things, if it worked, it got used. This looks exactly like the one we kept in the shop, dodgy wiring included. These things would take a bit of a beating with the overall vibrations and then the occasional off balance spin would really make things exciting.

That continuity tester is horrific!

Marc McKenzie

Early precursor to the modern taser!

Brooks Moses

Such fun! Such danger! Might I suggest swapping out the bulb for a 5V-powered LED, and putting a small USB power supply in the base to provide voltage for the probes and LED? If you use a deep-red light bulb and embed the LED inside it so you can't immediately see that it's an LED, it should look and function pretty much the same as original except for the arcing. And, of course, the modifications are completely reversible to OEM if and when desired.

I think this is one of those times where I'd forego originality and remove the probes of death and add an earth wire to the case...

Jeffrey Hatton

For safety sake, you could make a set of probe caps to cover and insulate the probe points.

Peter Laws

Since the Probes Of Death™ are at line voltage, it would probably be within electrical codes to put a standard 120 V plug/socket in line so you could at least unplug them when not in use. IANA Electrician, of course ...

I agree maybe some nice large ones on an insulating block?

Andrew Egerton

Fantastic. Glad I lived to see one of these.

Felix

You need to use a very low power lightbulb, because it also works as your current limiter.

Stuart Young

With the probes: Make a block of wood with 2 parallel holes in it big enough to take the wooden part of the probes, to act as a storage holder/protector! Extra points if you make some sort of detent mechanism or something to keep the probes stuck in the block, so that they don't just fall out if the cable moves or gets lightly pulled on. This could even be attached to a piece of wood that the growler gets mounted on, since it seems to be designed to be bolted to something.

Aaron Harlow

Exactly what I was thinking. Even if you never touch the probes, you're exciting giant chunks of metal with 120v AC which I could never be comfortable with.

Vee's Vexations

The detent mechanism is just making the holes slightly conical instead of perfectly tubular

"E" for Eric.... coincidence or destiny?...Who knows.....
