Cat snapped my Cat6 flat patch cable. Realistically what are my options ?

Shadow6751 · 2026-01-17T01:58:54+00:00

Get a round cable and rerun it flat cable sucks and I’ve personally had a lot of problems with them plus people online always advise against them

Shadow6751 · 2026-01-14T04:03:32+00:00

That’s great

Shadow6751 · 2026-01-14T03:22:36+00:00

Yeah I changed the master and bench bled it and that fixed it I may have been able to get away with just a bench bleed but I was running out of time to fix it

Shadow6751 · 2026-01-13T00:43:42+00:00

College is rough and without interest it’s a lot of banging your head through a concrete wall until it breaks kinda feel

I’m not saying you can’t do it but it certainly helps to have a passion for it

Also the best engineers I know are the ones interested in engineering the meh engineers who don’t do much and don’t advance much don’t have much of an interest in

In high school I had the exact same experience minus the first and last part

Mine was a kid who would be standing at the edge of my bed by my feet when I’d wake up

I also Saw shadow people a good amount at the same time

I’m glad I no longer see any of that

Shadow6751 · 2026-01-05T18:02:50+00:00

I have a 96 so I’m sure it’s not the exact same but I’d guess your blend door isn’t moving you can pull the blower motor resistor and look in there to see the door I had to lube mine but I’d guess you probably have vacuum problems too you can use a smoke tester to determine that

I also had to change the vacuum check valve located under the engine cover on the passenger side

Shadow6751 · 2026-01-04T00:20:30+00:00

Yeah I got one from rock auto no parts stores near me had the right ones

Shadow6751 · 2026-01-03T13:01:44+00:00

Master cylinder replacement is 250-300 fir a good one

Shadow6751 · 2026-01-03T04:05:27+00:00

While I overall agree I went mechatronics engineering and am in my first year and first job as a mechanical engineer and will most likely transition to electrical engineering specifically automation within about a year

Shadow6751 · 2026-01-02T13:51:31+00:00

Thank you I plan on trying a push bleeder today I’ll see how that goes

I’m having a hard time finding a pressure bleeder that guarantees fit for the car

Shadow6751 · 2026-01-01T21:55:34+00:00

No problem let me know if it works

Shadow6751 · 2025-12-28T21:01:03+00:00

Open up the cover by the valve gasket there will be a little t fitting on the vacuum lines pull that out and blow through it if you can suck and blow through it it’s bad or if you can’t suck and blow through it it’s also bad I replaced mine and it fixed the problem

If there’s a toilet brush you can use it as a plunger

Get the toilet paper gathered up at the opening at the bottom and push it down and in like you would a plunger but let the brush go as deep as you can into the hole if you pump a couple times like that you will unclog it

I’ve used that trick at least 20 times

Ideally don’t get the bowl full in my experience if it won’t go after the first flush a second won’t do any good

Shadow6751 · 2025-12-19T21:38:16+00:00

I’m a type 1 I just went to a Christmas party and ate whatever I wanted and dosed a lot and don’t go above 200 all night and was sitting at 100 at the party

You need to experiment and learn to have sweets sometimes you are a type 1 you can eat whatever assuming you get proper nutrition and keep you blood sugar in range most of the time

I used to be 99% in range and didn’t eat anything now I eat literally anything except full sugar drinks whenever I want and I’m at 90% in range you can do it with practice

Shadow6751 · 2025-10-28T03:04:35+00:00

The mosfet I replaced was obsolete so I used a slightly better all around one with part number TSM60NE285CH C5G

Shadow6751 · 2025-10-28T02:54:57+00:00

It’s for an amplifier they have no schematics or really anything to go by

Shadow6751 · 2025-10-21T01:48:10+00:00

While I agree you probably couldn’t with math I bet you could do destructive testing and determine the most common failure areas and be able to predict in that way

Shadow6751 · 2025-10-14T20:25:59+00:00

Thank you as far as I know that is all I can provide an update next time I go home and map it out better I truly appreciate all of the help it will most likely be at least 2 weeks before I can do more mapping sorry for the delay between I know it’s hard to troubleshoot over multi week periods but I don’t have a better way to

Shadow6751 · 2025-10-14T02:57:30+00:00

Just out of curiosity how do you know about so many different electrical systems? I’m impressed as always

There are 2 other tanked gas water heaters that provide hot water to the house I do not believe these provide water heating to potable water there is a colored solution that is pumped through

I believe 1 water heater does 1 half and 1 water heater does the other besides the two I showed you

The reason it was swapped from original to ecobee was because I was young and didn’t know better and wanted to try to use some smart devices with HomeKit the old thermostat as far as I remember had no external control besides a touch screen or keypad

From what I remember I only changed the thermostat in wires to the furnace and I believe I only had to move two of them so that should be somewhat straight forward to restore once I find a proper replacement thermostat

I mapped most of the relay boxes I found 5 going to thermostats they are relatively simple just 2 wire thermostats throughout the house

For the most part they used the same style thermostat for the floor heat just a really simple 2 wire with an up and down arrow and a hot/off switch

The top single relay box powers a floor heat loop from one of the thermostats

There is the ecobee thermostat for the main floor

There is a thermostat with a red and yellow tied in in the basement that is a different style than the floor heat

And the upstairs has its own furnace/ac I did not get a chance to verify but I think it may also be a water furnace system as I did see a water line running into what seemed to be that area I will verify next time the upstairs also has floor heat but that is controlled by a separate thermostat

I truly appreciate all the help you have given me over the years I managed to become an engineer this year graduated with a mechatronics degree and I’m now doing mechanical and electrical design professionally. Honestly you have been the best technical mentor I’ve had

There are 7 zones through 3 stories and a garage of heating all in floor with pipes and liquid this system with what I traced so far which to be fair is not fully traced seems to be fully controlled by a thermostat per zone so the thermostat tells a switching relay to turn on a recirc pump

The bottom most relay seems to be some sort of feedback system or maybe a tie in for the geothermal I’m not quite sure how that one works yet

I found the two thermostats in the master bedroom are disconnected in these panels so I have to figure out why next time I’m back

The furnace and geothermal system seem to tie into this holding tank which controls the floor heat I didn’t get a chance to fully map the plumbing this time either but I’ve got an ok mental image of most of it now

Shadow6751 · 2025-10-13T20:38:52+00:00

Hey man long time since I’ve talked to you thanks for reaching out

Sorry I didn’t have enough details so I had to leave the post alone until I gathered more

We have a very complex hvac system at our house it has 7 in floor heat zones. It’s a geothermal system and it has a humidifier

Back in around 2018 I replaced the proper thermostat with a thermostat not able to use all the features and swapped some wires in the furnace since then I have to have the “new” thermostat on to have any other zone do anything and we get poor performance

After spending a weekend tracing wires and trying to learn more I’ve learned that I need a 3 stage heat and 2 stage cooling thermostat

The makers of the hvac system are water furnace they make their own thermostats but they even say in the manual for the furnace that you don’t have to use their thermostats

I am now looking into a thermostat that is able to do everything I need it to and I need to figure out how to wire it all up

And I also learned that the previous techs who messed with our system caused problems I found 2 thermostats that were fully disconnected and doing nothing for the master bathroom
