    I'm trouble shooting a 3 channel, 2KW on each output, dimmer. One of the 3 works, getting about 115-120V on it. The 2 channels that are not is only getting an output of 30ishV. I check the triacs on each ch and they are good along with the 3 fuses. There are switches and dimming pots that I also made sure I had on the correct function. Tested the diodes and resistors on the board to search for any bad ones. The board had IC's, transistors, and caps that seems to be ok. Connection between leads and terminals seems good. Any suggestions?

    We need more information on this dimmer. Try to get hold of a circuit diagram or reverse engineer one if possible, then post the diagram for evaluation by the members of this forum.

    Ok will give it a shot. It's a project I'm trying to repair at my job; getting that circuit diagram depends on whether the manufacture will give me access to it.
