Glad I could help. I would still like to see which board you were working with if you are willing to email me those pictures I requested.

This may be an odd question but if you don't know what board you have how do you know how to hook it up correctly? They all wire differently and use different parts to control them. Best way to test a treadmill board is in the treadmill before disassembly. Then depending on the type of board there are other techniques for testing. Contact me through my website and send me pictures of your board and I may be able to identify it. Not exactly sure what you are referring to as "yellow tapped coil" but it is likely a transformer to step the AC coming from the wall down to less than 20V so it can be converted to DC to power other parts of the system. That is just a totally blind guess and I would need to see a picture to identify it for sure. A choke is not polarized, the current does not care how it goes through it however some chokes work better on the negative side and some work better on the positive side. Do you have an actual motor choke out of a treadmill or a component called a choke purchased off eBay or other source that "looked right". Asking because it happens all the time. Also send me pix of how it is hooked up and I will see if I can identify any issues.

@@dazecars Thats why im asking where to find out what board i have. The way i do it now is by taking pictures of the board while its still in the treadmill and by what knowledge ive learned from you or on the net

Again contact me through my website and send pictures.

The important thing is the blue wires are AC and AC is not directional. As long as you hook it up to the AC side of the circuit it doesn't matter how it is wired because all it is an in line switch. I put it in series with the hot.

@@dazecars thank you for that bit of information. I was confused on that

glad I could help, let me know if any other questions come up

Glad you liked it! Thanks.

I did, it was in a comercial grade unit

Glad I could help

In the video I said it was for an international and fits an entire range of years.

as long as the MC stroke is enough. I use 3/4" 7/8" on my own cars.

Thanks for the heads up

The feedback I have gotten is fully submerged zinc will etch but not pit. Once a dark gray layer covers the part the reaction either stops or slows.

never tried it but would be concerned with it turning rancid with time

Glad they were helpful!! My local ACE hardware store had tons of pulleys to choose from in their pulley and belt section. Adapting them to the motors sometimes required opening up the ID of the pulley or sleeving the shaft on the motor but there were lots of options out there.

They are for sure good cases

Originally I ran a DC capacitor in parallel with the motor after the rectifier. And while it did help clothe power I found a surging load. Not all SCRs are created equally you must get the good one and a choke is IMHA required every time.

Glad it was helpful!

It was a fun project

I need more information to know. The concept of a DC motor and power supply are relatively universal. What I am saying is you could restore it as is and if the power supply fails simply replace the power supply with something similar to what is used to drive a treadmill motor. You need to make sure the new power supply is within the correct specs but they are easily configurable. As to weather or not the treadmill motor would be a downgrade, lateral move, or upgrade, I would need to know the motor specs from the label. the more information you can provide the more help I can be.

How is that?

Of course, here you go: ua-cam.com/video/NUOCo01qARE/v-deo.htmlsi=WzsFgb6z5Z1JEIJk

@@dazecars Thank you!!!

my pleasure

It has to do with the carb body material. Yours must have been something other than aluminum, my guess would be a zinc alloy . ua-cam.com/video/9nCAZA6HThU/v-deo.htmlsi=lDItvTZnd5SYrxRW

@@dazecars I do believe that the Bendix carbs are a zinc based carb. It all your fault for not making your video two years ago, LOL!!

I will try and make future videos in a more timely fasion 😂😃🤣

Outlet wall. That strip is likely 10 amps or less. you want a 20 amp wall circuit

@@dazecars Thank you, because it was driving me nuts . Ill try the outlet

My pleasure.

Most but not all treadmill motors are DC and require an ac to dc converter. Most ac units are 3 phase requiring a 3 phase hook up and a VFD for variable speed.

@@dazecars thank you so much

my pleasure

I agree but I don’t think the isolation is necessary ( depending on the size of your fingers 😁) as MSD distributors use a virtually identical sized cap to the smaller one in this video.

Yes but only if the Variac can handle the amp draw of the 230 v device being run on it

Lots of ways to get it done but Reverse bleeding (filling an empty system by pumping fluid in through the SC bleeding screw is my preferred technique.

You make a valid point but It’s interesting when I was researching this I found a lot of strong opinions for and against either type of scale depending on a verity of criteria, but the overwhelming response was they both worked well in most situations.

@@dazecars Good to know, thanks

Glad I could help

Can you contact me through my website and send pictures of your board? I have not messed with an mc70 and the internet search I did came up with to many totally different boards all labeled mc70

@@dazecars I sent you an email with pictures.

I received it, thanks. I will answer here as it may help others. That board likely doesn’t use a choke from the factory as it has other cleaning components on board like the capacitors. I would also observe sparking at the brushes on hard starts. The board likely also has soft start which buy slowly increasing speed instead of trying to immediately ramp up at once reduces but does not fully eliminate the need for a choke. As to your question about the j5 and j4 not having played with an mc70 I have not experimented with the different options and do not know their function. Lots of boards have jumpers like that to test any number of functions specific to their board which are not always drive motor specific. Short of the ability to look at a circuit and determine its function (like an engineer which I am not) you need the pin out sheet. This lays out basic functions of connecting points on the board. Some manufacturers are really good at including such a sheet inside the treadmill and some don’t provide it at all. Let me know if I can be of any further assistance.

1-2 ohms is the butter zone

More watts is never an issue because more just means the resistor is set up to handle the current. More ohms slows the breaking action but is easier on the brushes. The sweat spot is 1-2 ohms.

@@dazecars Thank you!!

My pleasure

It’s whatever component popped. You can usually see physical damage. Like i said in the video if it’s the MOSFET or SCR replace both at the same time.

@@dazecars yeah c28 is gone looks like it blew, Thank you

My pleasure

Yep us crazy Americans don’t know how to say it. 😂

Agreed!!

Glad you liked it.

Yep need a matched set😄

What is the stroke of both, there might be air in the system which I can confirm or eliminate with those numbers? And don’t say all the air is out. It’s the most common trouble issue I see and absolute. . If it is not air than you can change one or the other to get a bit more SC travel but that has the potential to effect pedal effort.

looks to be very similar

Every board of this model type yes or every model of board no. I have the hack for about a half dozen boards but it is for sure board model type specific.

@@dazecars Thank you for your quick response. Im just wondering how many different boards and motors are out there, because everyone i come across is different. Is there a way to test you can perform to find out which wires do what and which wires you need to run the potentiometer?

I wish it was that simple but most are not hackable and not all of them that are hackable use a potentiometer as Some use a PWM. Good news is most motors will run on any hackable board or any board still utilizing the treadmill control panel.

i don't know why there's a line thru part of what I wrote -- it's all "good" stuff. K PS: DUDE U DO GUD WERK :) THANKs

Oh-another point-significant braking on a metal lathe requires that lathe chuck NOT BE A SCREW ON CHUCK cause like fly wheels they can come unscrewed real fast yikes 10+lbs of spinning castiron = no fun.. -- malso for a screw on lathe friction brake to chuck cud be possible BUT remember that it wud also tighten the chuck on the lathe spindle. ugh

I didn’t do it

A mechanical brake is a outstanding option but I like electric breaking only because it automatically engages every time the power is cut eregardless of how

Excellent point.

The answer is will oil improve its function yes, will it be as good as a bearing cap, no. This is demonstrated all the time in automotive applications There is a reason we use bearings in place of oil impregnated bushings. While they both work the difference between the two in night and day

glad I could help. Did you go with the two potentiometer system for course and fine speed control or just a single?

@@dazecars I just went with the single. It's for a belt grinder, I don't mind a small dead spot at the very beginning

👍

Glad you like it. Thanks for watching.

Might, it will depend on the amp draw of the motor. Should work but still need to confirm.

Hey mate I got them to work speed wise slow down yes speed up hmmm not sure till in posting

Let me know if any other questions come up.
