How to test transformer

[trinimd]

Hope you got your problem solved.
Just wanted to ask if anyone knows how to test the transformer.
I had a new board replaced a few months ago (blue board) with the green board (led screen) on top just like this set up.
Now I have no power at all.
Checked the round black limiter and it is not damaged. Checked fuse and its ok.
Would like to use my multimeter to test the transformer.
Can anyone help me on where I have to put my (harborfreight) multimeter?

The transformer is getting warm (not sure if that alone can confirm its working or not)



My technical skills: I have changed out the black limiter on a previous board and know how to do basic wiring. Never used a multimeter before

Re: New PCB board for Aquarite salt system, no power! HELP!

I was told I have to check the yellow wires with the multi-meter. Do i put the red probe and the black probe on each yellow wire?
ALso noticed there is a red and black on the top right. that would make more sense to me to use the multimeter probes there. Any input is appreciated.
thanks

Do you have AC input power? Can I assume you have Hayward AquaRite SWCG? If so, disconnect the yellow wires from the rectifier and main board. Set dvm to 200 ACV, put the blk and red test leads across the yellow wires. Turn on the AC power and let me know what you got!

Check this thread... Aquarite no lights

Btw, hope you're not creating multiple threads with the same topic.
I know you mentioned you're noob in using the DVM and I am guessing this is what you have. If yes, then just connect the test leads as shown and set pointer to 200 ACV. If you want to measure the incoming AC power above 200, then set the meter to 750 ACV but observe extreme cautions when measuring high voltage.
