Eric from Ottawa writes,
[The 15-91 I lately acquired] looks similar it's inwards peachy shape, but it doesn't run. It has a articulatio genus switch rather than a human foot pedal too it looks similar the motor controller has failed.
To attempt out it, I unscrewed the middle of the flywheel hence in that location was no charge too plugged it inwards too got nowhere, fifty-fifty amongst the articulatio genus switch inwards too fully engaged.
Do y'all intend it's worth re-wiring it to occupation a measure human foot pedal similar most of the ones I've seen?
Hi Eric, commencement off, a picayune almost your machine. The chrome rim on the handwheel summation the pattern on the faceplate, from the picayune chip of it that nosotros tin reckon inwards the photograph upwardly top, dot this machine is from the 1930s or early on 1940s (assuming those parts are original). The old-school cylindrical Singerlight visible inwards the photograph below too indicates the machine is from that era.
The “J-“ prefix on the series give away plate indicates your machine was made inwards Singer’s Canadian institute inwards Quebec.
Secondly, skillful on y'all for trying to run the motor amongst no load, that’s precisely the right commencement footstep to attempt out out a motor.
As you’ve observed, your machine uses a knee-activated controller.
For those readers unfamiliar amongst this device, it was an early on choice to the human foot pedal most of us know, too it eventually brutal out of favor. It consisted of a motor controller placed inwards the right side of the wooden base:
The cease of the removeable articulatio genus lever--which stows handily within the instance too underneath the machine, or occasionally upwardly inwards the domed lid via clasps, when non inwards use--“plugs” into the hole inwards the front end of the case.
Pressing against the lever would activate the motor controller, which is wired into the within of the three-pin terminal.
Eric, in that location are 3 possibilities here: 1) The ability cable is faulty. 2) The motor controller is faulty. 3) The potted motor itself is faulty. Hopefully it is #1 or #2 too non #3, equally the commencement 2 are easy, relatively cheap fixes.
To reckon if it’s the ability cable, endeavor turning the low-cal on. That’s non a 100% accurate attempt out because the bulb may move burnt out, but at the really least, if the low-cal does plough on y'all know there’s ability flowing through the cable. Another matter y'all tin produce is convey your cable to the identify of a friend amongst a vintage Singer--that cable volition agree a multifariousness of machines made inwards the 1930s, ‘40s, ‘50s too to a greater extent than or less inwards the ‘60s--and reckon if it powers his/her machine okay. If y'all decide your cable is what’s faulty, y'all tin companionship a replacement from Sew-Classic for U.S. of A. of America $7.95 right here. If y'all take to become amongst a dissimilar supplier, perchance individual local to y'all inwards Canada, banker's complaint that you’re looking for a “single-lead” (as opposed to “double-lead”) cable.
If the motor controller is the problem, it is totally “worth re-wiring it to occupation a measure human foot pedal,” to response that question, too the skillful intelligence is that it doesn’t quite require “re-wiring.” The motor controller leads are easily removed via 2 thumbscrews within the three-pin terminal. There’s no cutting of wire or soldering required, it’s a uncomplicated mechanical connection. To reckon how to take the leads, click here too await at the parts of the entry that pertain to removing the 2 motor leads, which inwards your instance are actually the controller leads. Be certain to banker's complaint which 2 pins inwards the in conclusion those leads connect to.
To supplant your motor controller amongst a human foot pedal, you’ll ask to pass a tad more. You’ll ask to purchase a human foot controller; the to the lowest degree expensive offered past times my preferred supplier, Sew-Classic again, goes for U.S. of A. of America $11.95.
What y'all tin produce is connect the 2 leads from your novel human foot pedal to the same 2 posts that y'all disconnected the master motor controller leads from. Then y'all tin take the onetime motor controller (attached via screws) from that compartment on the right of the wooden base, too store the pedal there.
Alternatively, if you’d similar an master Singer human foot pedal, y'all tin banking corporation check eBay.
If it’s the motor that’s bad, too hence you’ve got a fair amount of piece of work ahead of y'all to figure out what precisely is incorrect amongst it, too if it’s fixable. You may desire to browse the consummate “How to Re-Wire a Potted Motor” to decide how to disassemble the motor hence that y'all tin inspect the wiring, 1 possible culprit. But if it’s something beyond bad wiring--a burnt-out acre core, for example--that’s beyond the gain of my fix-it knowledge.
If y'all produce decide the potted motor is what’s faulty, y'all volition occasionally spot individual selling 1 on eBay.
Whatever y'all do, delight don’t throw that motor controller out, fifty-fifty if y'all decide it’s bad; if y'all rest inwards this hobby long enough, y'all volition eventually run into individual else who may ask a part from that controller--even if it’s simply a unmarried screw--so y'all may move able to attention them rescue an otherwise non-functioning machine. Ditto amongst the articulatio genus lever.
Best of luck amongst it, congrats on the machine--I honey those chrome-rimmed handwheels!--and allow us all know how it turns out.
