Retired now from 45 years as HVAC Tech. When I had a short like that in the outdoor unit the first thing I checked was for a small burn mark on the units cover where the control wires come in to the unit. The wires would be up against the door and would vibrate thru the insulation after a few years of running and finally short and leave a small burn mafk on the door. When you were putting the door back on it looked like a burn mark on door on the lable. Love your videos and love the way you troubleshoot. Your expertise shows.
You turn a lot of screws by hand every day. Your hands will eventually tell you they've got too many miles on them. Get a lightweight electric screwdriver and use it so you don't put miles on your hands spinning screws you don't need to spin by hand. One other thing, cutting the ring off the terminal and leaving the ferrule isn't an approved use of the wiring device because it's too hard. A terminal block is a pressure terminal that is worked out for the screw to press soft copper wire to make enough contact area to the tongue. The hard ferrule doesn't create as much area. The screw side mashes better but its electrically worthless, screw threads have only a tiny contact area. What you're doing usually works initially and many will work indefinitely or at least longer than the contactor, but eventually some will show the current crowding as hot spotting, it will look like localized corrosion. Eventually the terminal overheats and the contactor will fail. You do a good job of tightening the lug to try to compensate, but working up enough torque is likely to break the contactor case before you get enough area. Get an automatic wire stripper you like enough to use or a buy a bottle of quick connect screw terminals so you can leave the ring on.
1 ton for that Bonus room seems alot, no? They be changing filters with the construction going on. I like that short probe tool, gotta look in on getting one. Nice explanation of what, how, and to find a short. Nice job Ted.
Awesome tool. Does it matter putting 5amp fuse on board that says 3amp fuse on it? And if you take screws out of back of the contactor the black plastic on side, slides out and you can see the coil.
I think contactor coils are failing way more than they used to these days. Even though my last short was a bad tstat wire beween the A-H and tstat, on a 6yr old metal stud condo with a Carrier. I was using my lil popper. And I do compressor wires the same way in lugs.😶
Those lugs are not rated for a finely stranded wire, thus requiring a ferrule to crimp to so that the wires do no break under the set screw. So you are correct in the way you are installing wires into the device
I can not get the fan speed turned up on Pepe's (Your old neighbor.) Trane. On fan only it blows on the lowest speed. It will not let me change taps. What am I missing?? PLEASE HEP a brother out!!!! I will be calling you about this soon.. : )
You could have left that short pro connected then when you connected the contactor it would have engaged. I do it a lot but like you said, just another way to skin that damn cat. 😊
Glad I'm not the customer of yours. Because yes, there is a need to put gauge on it. Regardless of how you feel me as a customer is what I am paying for. Being a SERVICE PROVIDER is just that !! Provide FULL SERVICE, to the "best of your ability " I guess. Your now un-employed
First of all the customer was only billed for the low-voltage diagnostic, and the contactor replacement. So you’re mistaken, the customer did not pay for anything that I neglected to do. The general maintenance is done by a different tech at a different time of year, and is not combined with a repair situation, therefore, full service to the air conditioner or furnace was not performed nor was the customer billed for it. Second of all, it is up to me and my experience as to whether I see a need to connect gauges and affect a port that can easily create a leak for no reason. If you think you know better than the service tech, then you may as well service your own unit. And lastly, I agree with you, I am very glad that you’re not my customer either. If you don’t trust a professional, you should not hire them. And if you do hire a professional, you should trust them. You do not know more than me about Hvac. You have made that obvious. I just don’t throw gauges uselessly on every machine I walk up to. We take temperature readings, line temp readings, Delta T readings, etc. and there are many things we can do without disturbing the refrigeration system whatsoever. I hope your defensive posture pays off for you and other situations of life, but in this particular instance, it only makes you appear to be difficult to get along with.
I've been using a Short Pro Tool ever sense they came out and I don't know why more people are not using them.Good tool
Me too

After watching you cut those connectors I started doing the same thing and it works great. So much better than trying to deal with any stranded wire.
Nice troubleshooting and work Ted.
Great example of tracking an electrical fault, thanks!
Good work and nice demo of the Short Pro Tool! Thanks!
Gonna start calling you the one handed film bandit. Great vids man!
Interesting way you landed the incoming power wires to the contactor. Makes sense. Better contact with wires. I’m gonna use that. Thanks!
Great diagnosis and working the issue quickly and efficiently!
This was only a simple fix because of your experience and knowledge. I dont think a youngin' would have figured it out quite that easily.
I am getting one of those short pro tools. Great video as usual.
Love that tool. Better than the little popper.

Videos on back to back days . YES !
Nice looking install ... Love these chasing shorts vids that uses good troubleshooting like you did ... Thx
Great job Ted I have tool need to break it out and use more !
Great video. Very informative. Finding low voltage shorts always gives me problems.
Using those old connectors as ferrules is perfectly OK. Much better than bare wires. 👍
1 ton for that Bonus room seems alot, no? They be changing filters with the construction going on. I like that short probe tool, gotta look in on getting one. Nice explanation of what, how, and to find a short. Nice job Ted.
This is one of the better videos I’ve watched, of yours 👍
“Short Pro Tool” with current limiting and auto reset for the win. Beats the heck out of a Little Popper.
Nice job...Nice house too. Plenty of HVAC...all 2 stories should 2 or 3 units for full control and options. A few smaller units tend to work best.
Ted is The Man! 😎👍
🚨🚨🚨
A nice check over job Ted 👍 Au
Awesome tool. Does it matter putting 5amp fuse on board that says 3amp fuse on it? And if you take screws out of back of the contactor the black plastic on side, slides out and you can see the coil.
I've yet to see my Short Pro light up. Somehow I had imagined it would light up orange.
Great little tool, Where did you purchase it? Thanks for the video.
I leave the short pro connected while testing outside. Finds the problem quick.
Nice. Good find Ted.
I do the same thing with contactor lugs. Never had a problem.
I think contactor coils are failing way more than they used to these days. Even though my last short was a bad tstat wire beween the A-H and tstat, on a 6yr old metal stud condo with a Carrier. I was using my lil popper. And I do compressor wires the same way in lugs.😶
This is Not Simple.....a lot of experiences going into troubleshooting to pinpoint the Problem 👍
Great troubleshooting my man!
Those lugs are not rated for a finely stranded wire, thus requiring a ferrule to crimp to so that the wires do no break under the set screw. So you are correct in the way you are installing wires into the device
It certainly isn’t…, such good English!!! 👍
Holy cow I haven't seen a dico thermostat in a while basically white rodgers 😊
Ah, the famous Carrier run cap that you'll be back for soon.
How many ohms are you looking for when you ohm out the contactor?
one of the best video. I stared to wach all your videos. can you tell me where can I buy the screw driver that one you use in the video
That's a Klein, not sure model.
Thats a nice pen you have their Ted.
what screw driver is that you use??
You could OHM out your contactor from furnace or thermostat.
IMO that's a more secure way to secure those wires on the contactor. I wish they were all like that.
1.5 pole contactors should always read
Are you sponsored by the short pro tool can I use something to get a discount on it
Filter drier in the attic space is crazy lol
By doing what you did I'd think you'd get alot better contact instead of just putting bare wire in the contactor
As always very nice video
Excellent video 👍 👍
I can not get the fan speed turned up on Pepe's (Your old neighbor.) Trane. On fan only it blows on the lowest speed. It will not let me change taps. What am I missing?? PLEASE HEP a brother out!!!! I will be calling you about this soon.. : )
Call me up man …. I can tell you how.
You could have left that short pro connected then when you connected the contactor it would have engaged. I do it a lot but like you said, just another way to skin that damn cat. 😊
Nice work 😊
How many times have you forgot to mark the box and it wound up in your parts bin ? Lol
Check the muffler bearings
Yes, and the blinker fluid.
A good idea is to add 50ml of sulphuric acid to the compressor before regassing
If it's Dico it must be the best.
What tool is that you are using
Short pro tool
I ohm y and commong inside and itll lead u to contactor straight off bat sometimes
Smart !!
Sell them some new modern T-stats when you return with filters. Those old, mismatched ones look hideous.
Last
Nice job
Big house!!!
And beautiful, like so many of the homes he works in
Cool
I have been cutting them ends off for years
Ted Cook is workin’ again, Y’all !
I believe the contactor is called a double pole single throw contact
Tool link?
Someone had red on common is supposed to be blue
Helicopter 🚁

NO LIGHT IN A ATTIC WITH MECHANICALS IN IT IS SO C H E A P DID I SAY C H E A P
very n8ce trouble shooting! china keeps you in business thats for sure!
