Wiring help for Electric Hoist Cummins #6832

I have a problem with this hoist, I am fixing it for a friend. Unfortunately the Forward/Reverse switch was already disconnected, before I got into it, the switch is a Mom-Off-Mom DPDT switch. The motor has only three wires going into it, which control the forward, reverse and electric brake functions. There is also a large 70uf electrolytic capacitor, which was disconnected. Any info on the motor would be a great help (110vac-60hz). I have reverse engineered a partial wiring diagram, but it's not much help, without knowing how to wire the motor. My email is emjensen@fmctc.com Thanks in advance.

Hi,

Before removing the motor I would check for sure that you are getting power to the motor...if so then the motor is gone...there could be an internal overload that went out on it....

Check your yellow pages for a motor repair shop, many times they can fix the motor for a few bucks and they will give you an estimate before you okay the repair.

SOURCE: Need the electrical capacitor conecction

There is more to the unit than just capacitor. The unit puts a capacitor between one of the lines and the third leg of the three phase motor. There is a voltage sensing relay that senses a certain voltage and when that is reached on the third leg, the capacitor is disconnected by a larger relay controlled by the voltage sensing relay. Note that the available HP will be about 60% of the rated HP when run on true three phase power.

If this is a 3HP I don't think you can switch it. However there is usually a wiring diagram under the square box on the side of the motor.

Hi, Recently purchased a factory rebuilt 11255vsr and have put it to hard use. I'm noticing oil on the bit shanks, high heat @ front end, louder and louder noise. Nothing critical yet, but I hear it...


Here goes, the only real problem with disassembly is removing the shift selector, but first remove the bit lock mechanism, the dust shield pulls off and then you will find a retainer under that remove these and put them in toe order removed or take some pics to help later in reassembly. Removing the selector what you have to do is turn it to the hammer position and then depress the plunger all the way and turn it past the hammer cog, this will release the tabs that lock it in. As far as grease they make a special lube for the gears inside this tool. The wear items would be the armature/gear. To check for this before disassembly run the tool NO LOAD in forward and listen, then reverse the rotation and do the same, if is quieter that is where I would start to look. The screws holding the gearcase on are T20 torx. I would suggest going to "ereplacementparts.com" and downloading a schematic so you know what you are getting into.

I was using my friends Craftsman Rotary tool to shave down a metal door jamb and it got hot so i shut it off. Turned it back on for a second, and has not worked since. It's been 3 days. Is there a way...


You probably burned up the brushes.You can take it to Sears and have them send it in to have them replaced, but in the long run it will be cheaper and a lot faster to buy a new one. Rotary tools are not made to take a lot of stress. Besides your friend will see how much of a nice guy you are and how honest you are and won't be afraid to lend you tools in the future.

Hi there i have a makita HR2470 and last week i was chasing out a wall and it just stopped mid chase,i checked the transformer it was connected too that was fine,then i've checked the lead at both ends all...


Try to make a direct JUMPER.Take an old electrical cord cable and plug it in the electric socket and the other end of the cord with 2 cables already peel off and jump the + and - to the + / - of the hammer and see if power on if so the on/off switch is bad and need to replace.If the problem
persist probably the motor is burn.

My dremel works intermitently. As I move the switch from one speed to another it will momentarlly run. Whats the problem? THANKS


You described intermitten pwer supply, follow this procedure:

1. check your power cord for breaks or kinks, especially where it join the piece or plug
2. if cord is ok, check/replace brushes.

To check/replace brushes on dremel 395 follow this procedure:

1. switch off unit, remove power cord.
2. with flat screwdriver remove gently brush covers, WATCH FOR LITTLE SPRINGS!!!
3. check brushes for wear, springs if connect correctly, if brushes are thinner than 3.2mm (1/8") replace with new ones, this check should be carried regardless after about 50hrs of use, brushes last about 50 to 60hrs in normal use.

In unlikely case that it is switch, this is as well very easy replaceable.

1. switch off unit
2. remove cable from power source
3. remove brushes following previous procedure
4. remove collar from front of the piece
5. remove side screws and gently pry apart halves, label side up
6. replace switch
7. screw pieces back in reverse order
8. replace back brushes.

All parts are easy available, when purchase brushes or switch, be aware that they fit only particular model!

I would recommend clean table with butcher paper on top, torx/hex screwdriver, philips screwdriver, flat screwdriver - these vary from country to country, I cannot provide what exactly tools you will need, you need to check what screws are holding your piece together, little long nose pliers can be helpful as well.

As you pull handpiece apart put your parts in order in whihc you pulled them apart, when you put them back, it will be easy to put them back in reverse order in which them come apart. For changing brushes you need about 5min (assign 15min), for changing switch or faulty power cord you need about 1h (assign 3hrs), assigned time is theoretical, prctically multiply it by 3...

If you have anymore questions, or require more detailed instructions, do not hesitate to follow this thread and leave note.

Leave note how it go, thanx!

No operation


Hello their, thanks for trying fixya, the issue with these type of tools is normally the ac motor, their are many diffident types used but yours in particular 120V, 50-60 Hz, AC, 1.15 amp double insulated motor. Operates from 5,000 to 30,000 RP, their is a electric motor that may have failed on you or the switch could burned out. this is possible when the contacts are shorted for to long become to hot and overload the small circuit used to control potential voltages to the motor, consider it like a variable pot switch.

a simple test here would be you can take the unit apart easily enough and unplug from wall, make sure you have no voltage from mains going in. when the unit is not plugged in get your trusty voltage ohm meter or vom

Switch does not work correctly nothing until its nearly full up then its going to slow


You have an open spot in the switch. You will need to replace the variable speed switch. The part number is 2610925722 and the manual for the tool says it is $14.00. (Though this may have changed since the manual was printed) Unfortunately the switch is unavailable according to Bosch. You may be able to pick one up on ebay. Good Luck.
