Lost 4 Channels on one controller

Recommended Posts

I lost channels 3, 4, 10, & 16 on one controller last night. Two of the lost channels have 100 minis each on them and the other two channels have 400 minis on each of them. Everything worked fine the previous night. Checked the power connections (extension cords) and everything appears OK. Everything has worked fine since Thanksgiving. No rain in over two months, so moisture shouldn't be a problem. Will get out there in the daylight to check more closely. Any ideas?

If you have a volt meter, check the voltage output from the cords at the controller itself. This will quickly tell you if it is a problem with the controller versus a problem with the lights. If it is a problem with the controller, the first thing I would do is replace the fuse.

Other details are required: What type of unit do you have, is it a build it yourself.

Would not be a fuse. You stated that 3,4,10 and 16 were out. Channels 3 and 4 are on the same side of the board and Channels 10 and 16 are on the other side of the board. If a fuse was blown then it would effect channels 1-8 for the left side of the board, OR if the right fuse would blow the entire board would be done, because the logic is powered from the right side.

I would venture to say that coinsicence you lost those strings. If you can get to the strings try plugging them into a always on power source.

Could be the fuse in the light set itself. Change the fuses in the first set and give it another try.

Yeah, I've had critters chewing into my mini's. One in particular, I kept losing the same strands each night. The ones bordering my driveway and intersected at a sidewalk. It would be chewed clean through inches from where I last repaired it the last time. I ended up giving in and moved it so that whatever was chewing an access road through the lights would leave it alone. So far, so good. Nothing has touched it in a few weeks.

I have done a little further investigation this morning and need to make a correction to my first post. All channels lost are on one side of a controller and channels 1 - 8 are out, not the channels I previously listed. The board is a factory assembled 1602. I have not checked the fuse, but I am using the jumper between the two sides of the board and channels 9-16 are OK, so I don't think it is the fuse. Everything on this controller has worked flawlessly since Thanksgiving; I have not changed anything in the sequencing, additional lights, etc.

The jumper supplies power to the other board but the fuse still protects that other side. I bet it's the fuse for channels 1-8 on the left side.

Just my thoughts,

Is it a CTB16DWHS or is it a LOR1600W???

The reason I ask has to do with how the jumper would be installed. If the jumpers are installed per the user's guide then the fuse on channels 1-8 is not in the circuit. The fuse on 9-16 protects all 16 channels.

If the jumper is not installed per the users guide then the fuse on 1-8 may actually be in the circuit... It could be blown and thus channels 1-8 are out.

If it is not a fuse then it may be the jumper connection itself. Do you ahave any way to measure if there is voltage on the left side of the fuse on the left side of the board?

Dan, It is wired per the instructiions -- no fuse in the left hand side (channels 1-8), however, I have discovered the problem. As you mentioned, it was the jumper itself. I was not getting any voltage to the left side channels. When I replaced the jumper, everything worked again. Did an ohm check on the removed jumper -- intermittent readings, so the jumper is broken some how. Jumper was solid 12 gauge wire, don't know how it could have been broken, but replacing the jumper solved the problem. So, you can mark this one resolved.

Edit: To answer your other question, it is a 1600 green board.
