Help one of four Pairui drivers dimmed all of the sudden

I have been running four Pairui 250s with 20cobs for about 6 weeks with no trouble. They were fine last night when lights came on, but this morning one looks like it is dimmed way down. I did raise the light last night but it was running fine after i raised it. I soldered the DC side at the driver and wago at the cobs, i guess i will cut out my solder and wago the wires. And make sure the connections along the 5 cobs are secure. If you guys that know more than me ( which is all of you) have any ideas please let me know. I have a hell of a run going and this is going to cost me big time if i dont get it fixed fast.

are you using a dimmer knob/pot on this driver? and could it be somehow grounded out now since you raised the light?

yeah id check the dimmer circuit first

No pot they are capped off with electrical tape, i will check it though. thanks

If there is a bad connection at the cobs would they even light up at all? I used the wire cutter sent which is stranded and was a pain in the ass to get them into cob holder is why i ask.

solid is always my go-to. if its stranded tin the ends with solder

I will check dimmer wires to make sure they are capped and all the connections at the cobs and wago the DC connection that i soldered, thats all i can think to do. I actually just placed a order with you cobkits friday or thursday, i will try to add a 250watt driver to my order now in case my pairui has crapped out.
