Topic tags/keywords: band-saw band saw bandsaw switch wiring electrical help

I am putting a riser kit on my band saw and had to disconnect the switch to do it. I thought I was going to complete it right away so didn’t take any pictures of the hook up like I usually do when taking apart things with which I am not fully versed in. Well, some time has passed and now I don’t know which plug goes where. I had thought (there’s that word again) I did but when I tried it, the lights dimmed and the breaker tripped before any (I hope!) harm was done.

I can wire light switches and house plugs all right but this stuff is a little beyond me. I tried surfing the web but there’s so many different things that crop up that that approach is hopeless. I need a little help in hooking this up.

It is 110. It’s the HF band saw (Hey don’t laugh. Look close and you’ll see it’s a twin to the older Grizz and probably came out of the same factory as the much more expensive Jet saw). Anyway, on my budget it’s this or no band saw at all. So I like it just fine.

I have some pics here. (never mind the mess. It’s in my barn and I am working on that to0. It takes forever to do anything when you’re disabled and teaching 3 boys at the same time!

For common terminology, I marked one picture with circles and stuff (2nd pic down). The switch is oriented as it will be when it’s turned around and plugged in. I figured for the switch prongs, start from top left as #1 and going clock-wise.

Note there are two sets of wires. I figure we could just call the one set Yellow hot and neutral and the other Blue hot and neutral, if that makes any sense. I figure that way we’re all looking at and talking about the same things.

So here’s hoping somebody can get me wired up! HELLPPP! (Pleeeze?)
THANX!!!

It’s going to be a DPST switch, so it makes/breaks both conductors. Get a meter and figure out which pair of wires are coming from the wall plug. The other pair will be to the motor. One set of wires will go to the two middle lugs on the switch, and the other pair to the other two lugs. I’d use a meter just to verify the switch orientation first tough. And don’t forget about the ground wires :)

The neutral terminals should communicate so if you can look on the back of the plate or check ohms that will tell you.

Once you figure that out, the rest is simple its the black leads are power and switch you should be able to determine which leg goes to motor and power.
Power is usually on bottom, but even if you get that backwards it will be like turning switch upside down (on when off/off when on).

I cases like this you can also get clues by the length and/or bend of the wires if one obviously won’t reach that helps you figure it out.

Regrettably, I managed to learn a “Wiggy” but never got around to learning an ohm meter. Got a cheap one and can check batteries but that’s all. Any clues on how to do THAT?
Sorry but it looks like I’m one dumb bunny!

Wrap a bare wire around the plug ends (the prongs that plug into the wall outlet) to short them together.. Then set your meter for resistance and touch the probes across any two wires up at the switch (try black/white pairs first). If the meter goes to zero, you found your power cord pair and the other pair is the motor. Keep probing until you find it. That is about as basic as it gets and how you test for continuity with the meter. Same thing can be done with testing the switch.

Brad

Looks like you have 2 cables coming into the box. One will be the hots and the other the motor. Put one cable’s wires on the top terminals and the other’s on the bottom pair. If you know how to use a wiggy, the top should be the line or hots. Good luck.

Depending on the brand of circuit breaker, that short that popped it may have wiped out the contacts in the switch. ;-(

All is well, problem solved. Being from Texas I lack “Yankee ingenuity” so I used Southern genius! (;^)

I was setting up something on the lathe when I noticed the switch was about the same. Then we noticed (sons in tow) the Oscillating Spindle Sander had exactly the same switch. (Just about every thing I have is from HF except my table saw and 48” belt sander.) Well, we flipped the old sander over, traced the wires. Hooked up the band saw, plugged it in, flipped o n the breaker and voila’! Low and behold it even worked! I managed to not have fried anything , thankfully.

So end of story. Many thanks to all who helped. I will save your comments for future reference.

Have your say...
