Great troubleshooting. I have trained many computer technicians and engineers and troubleshooting is not only a skill but an art. You clearly have the knack!
Great video of troubleshooting. Not only replacing a power supply but tracing the root cause of the problem (earth fault). Very essential in ballasting/deballasting and bunkering operation. Good Job lecky. Salute
Previously I have located shorts using a TDR because it can give you a "distance to fault" and if you move to a different probe point you'll either be closer or further, although with lots of open circuits in this way, it might be harder than when I do it with data lines. Another electronics technique from circuit diagnosis is to use a micro-Ohms meter so you can see the very small differences in resistance as you get closer to the fault. Both these are more expensive/complex than simply disconnecting each node and checking it, but time is money in some cases.
. Breakers and fuses are mainly there to protect the wiring from burning up, but I would install a fast blow, it sometimes protects dc power supplys. The 3amp uc1 cello lite fuse you have shown is a time delay fuse. Slow blow fuses will fry power supplys for sure.
Lmao..so will not um...fuck up the new power supply...nice Jake If ya can't find the words...cuss at it till it works... Your on your way to becoming a honorary American sailor buddy 👍
Curious on when to use a ground on a vessel? My main job is a diesel mechanic. When I watch electricians, I've heard them say things like never to use a ground, or the hull is a ground. Should a ground on a circuit be set up like a residential electrical?
Hello I have questions why same voltage different ampere?.. and before that I had got the answer ampere from friend value ampere depends on load work... So That right or not?
In the last part, when he is measuring one by one the white wires (going to the limit switches of the valves). He measured line to earth resistance and from there he was able to see which particular valve was causing the earth fault.
good job.but even reading 70 k ohm is not too much earthing .by equation I=24 v/70000 ohm=3 mA .so I think that's not the main reason for burned power supply
I'm a refrigeration service technician, specializing in light commercial however I have experience in supermarket refrigeration as well. I have an AA in refrigeration mechanics but I am wondering how much more education and training I would need to work as a marine electrician like yourself?
You can work on passenger ships as an HVAC technician. You need to speak to a crewing agency near you, write down their suggestions. Inform yourself what it means to work on sea. Maybe the lifestyle is not suitable for you or maybe your health does not allow it. Look at an job opening for a hvac technician on passenger ships to have a feeling for the requirements. You can also work as an reefer technician on container ship, also check job description.
Good video. How did you earth chase at the start of the video? Did you put the neg and pos probes across the fuse and it should read OL but read 70k ohms indicating earth?
The line is line-to-neutral and if you test for resistance between the two you should not get resistance and it means not shorted. The negative or neutral is bound to grounding, so he focus on hot line side which he found out shorted or connected to ground or having earth fault. He test all others(connected to line side) line to ground to determine which is connected to ground/shorted. That's all I understand.
@@cck1496 I think it's for safety and at the same time reducing the work itself. Imagine the line below the fuse is good(no line to ground fault), you will just focus on upper side of the fuse, and it's just a wire so it's easier troubleshooting
Need help here. How can the Power Supply be burned or shorted when the fuse was intact to begin with? Shouldn’t the fuse be burned down first and save the power supply?
Thank you sir new learning! May question po ako sir anu po ginawa nyu sa isolated cable the one that's causing the fault. Bakit na disregard napo. Wla po ba cyang bilang sa ckt diagram sir. Salmt po
hi, bubuksan pa yung valve na yun kung ano problema but for the mean time hindi muna magbibigay ng indications sa panel kung open siya or close pero magagamit parin siya yun nga lang need i check manually kung talagang naka bukas or sara sa actual.
@@leckyjake Makes sense at hindi rin sya madedetect ng 110v sa low insulation. Dapat may sarili sya kasama sa panel nya. This is really good as an additional learning. Thanks sir jake.
Good day sir. I would like to ask about my reefer trouble for STARCOOL. SET POINT = - 3.0, SUPPLY = 11.6, RETURN= 12.3. After 4 to 5 hours na mamatay po yong compressor nya. Pro wala nmn pong alarm sa panel. Ano po kaya problema nya. Please confirm po salamat
Laughed so hard when he said 'fuck up the new psu' not used to him swearing😆
I can definitely say why cuz what he did was was definitely time consuming. 😂
10:23 bahhahah cracked me up.

thank you for this wonderful comment
You are very good at your job,tracking electrical faults is not easy.
Awesome troubleshooting. 🥇

Great job. I'm retired and I really miss searching out faults like this.
Extremely informative and God bless you, Bro
Thank you sir,your vedio is very good and useful.
excellent troubleshooting sir patience is the key on isolating trouble on electrical control system👍Godbless and keepsafe sir
Saludos desde México 🇲🇽. Greetings from Mexico. Excelente 👌👍
thank you very much
Nice. Good Job Sir! 👍
Galing mo talaga sir..thank you for sharing.
Keep up the good work your videos inspired me to become an ETO . you're awesome 😎👍
i am a big fan of your work sir i have learned a lot from your videos.
Lots of love for you from India
Thanks for sharing!
Very informative, thanks.
Good Job Partner.. Safety First
thats the trouble shoot very tensions need patience..but you did great job i learn that work...keep it up
Thank you sir for your advice and knowledge sharing
thank you for the support
Good troubleshooting
galing kabayan..

great vid . informative !!
Nothing like a good ground fault to chase down , job well done
Thank you sir..as a trainee ETO I must salute you..
thank you for your comment
I hope i could work with you someday.. but the video giving alot of inspirations and lessons.. terimakasih po
you are the king boss
I hope you make another video with the cause and repair.
Lmao..so will not um...fuck up the new power supply...nice Jake
If ya can't find the words...cuss at it till it works...

70k ohm seems like a high resistance to cause damage to a 2 amp power supply! But I suppose it could be a non linear thing like water in a connection
Galing sir 😀👍 moore. Hehe
thank you for watching

Please show us how to take 24 vol earth alarm for battery charger room Japanese type vesel. From one Fan of U.
But why didn't the fuse blow if the power supply rating was more than 3 amps why didn't the 3 amp fuse blow first
Hello I have questions why same voltage different ampere?.. and before that I had got the answer ampere from friend value ampere depends on load work... So That right or not?
What does "lecky" mean? Is it Tagalog? Thanks, good sir! I love watching your vids!!!
Could those power supplies be still good and were only in current limit?
Awesome video, I only did not understand - how did you found which valve is the culprit?

It is an indication that something is not right. And the fluke only measures at a few volts. At 24V the resistance can be a lot lower.
Good video. What is FG on Power Supply & U & V lines feeding the Power Supply?
I am mechanical. Thanks.
frame ground
Wer it does belong sir d wire did u isolate..?
U should teach diagram
Hlo sir. Can you please make a video about how to charge freon properly to reefer.
Total star
thanks

First you need to train as a merchant mariner. School is the easiest way to start.
You can work on passenger ships as an HVAC technician.
You need to speak to a crewing agency near you, write down their suggestions.

Is it important to remove the fuse for checking the ground fault?
Thanks.

@@andyfannan8298 Yes

I think the fuse is to high value rating. Use the correct fuse size.
Sir generator wiring diagram make video on it kindly.
have some for the governor. pa check nalang sa channel
Helo Sir ask ko lang po about sa battery na lead acid. Pwede ba haluan ng battery solution ang battery kahit kaunti lang like 5cc?
i suggest follow kung ano ang specs at required sa batteries ninyo.

@@leckyjake Thank you sir.
Hindi ba sya kasama sa grounding alarm ng 24v sir jake?
hindi siya kasi ang main supply is 100V so kasama sa 110V na system
@@leckyjake Makes sense at hindi rin sya madedetect ng 110v sa low insulation. Dapat may sarili sya kasama sa panel nya. This is really good as an additional learning. Thanks sir jake.

better check the pressure. to troubleshoot, kailangan alam mo yung working pressures.
@@leckyjake pressure check muna gagawin ko dito sir?
Goodmorning po sir.. Sir panaano po ba proper na pag refill nang freon sa reefer container. Nka off po yung compressor motor or naka andar po? Salamat
