    Kole Audio TRAX1-5500D Missing Component?

    Q nearly always mean transistor. My guess is it's a mosfet used to switch on the amp? The 600mv pad likely goes to the gate. Yes, if we know where the other two traces go that would be helpful. Perhaps the power on relay circuit?

    Single to three phase... sort of...

    Great question, but I don't think that's possible for 3 phase since the reactive phase shift can't be more than 90°. Yes, 2 phase power circuits (mostly obsolete) are 90° apart. Single split phase circuits are 180° apart which is essentially the opposite polarity. And 3 phase needs to be 120°...

    First, That's three questions. Second, I told you what I need to decern what is going on based on the limited info given. Third, No I don't have a schematic nor is it my responsibility to do your research. Forth, Yes I know how to test a remote, but I understand that verifying some basic...

    Show me the back of the bezel with the power switch and main fuse. I need to know where the leads go from there. Yes, I see the two transformers one is either a step-up (or down) and the other is a toriadal type or an inductor use as a choke. I'd hold off with measurements until we know what...

    Much better pics. Where does the household power plug connect? 120v plug? I ask because the boards are European marked. That white board is likely for filtering, but I don't know what feeds J2 and J4 (in). Does this come from secondary side of transformer, or does the main line power go there...

    Ok a bit dark but good so far. Can you identify where some of the cables originate? What I like to do is open a photo in Microsoft paint and edit it to add writing to identify things. Or, just sketch out on paper .. eg; 120v power comes in the transformer, output of transformer goes to J4-1...

    I don't see any transformer. Shown in the 10th pic of your last post is a vacuum air pump (on top) and solenoid values beneath it which directs the flow.

    I believe this is where your DC power supply originates. Can you give a close-up well lit of this region? Where do those two wires next to the glass fuse go? We'll need a photo of the traces on the other side of that region of the board also. I'm guessing you've already checked this fuse?

    A wee bit out of focus but a great start. I didn't know you were talking the remote apart already but that's ok. My primary focus is the board where power comes in. A close up thats well lit to shows component details would be ideal. Even if you have to take quadrant pictures of each board...

    Power cord for old knitting machine.

    I presume they're saying two separate outputs of 9.6vac@50hz. If you run it at 60hz the motor will run a little faster than the original 50hz. If there is electronics involved that difference may be a problem. Can you post a picture of the plug/back of machine where power cord is? It may...

    Ok, it's quite different than I imagined. Unfortunately, due to the lack of info, the only way to determine if the remote is working is to first take it apart to figure out how the circuit works. You could just try to read if you have DC voltage on two of the pins but I don't recommend...

    When you say "remote", does it look like this? Is that the 4pin cable coming out of the bottom? If you can take some clear close-up pics of the main board (front and back) that you were checking that would be very helpful. If your lucky, It's a power supply problem ahead of the "remote". It...

    Mike, you need to be a bit more forthcoming with facts, sketches, close-up photos or anything else that will lend a clue to what's going on. When does the fuse blow? When you plug it in? After you hit the power button? Is there a separate power switch or just the interface panel push button...

    Must unplug and replug power to make Cooker Hood / Kitchen-Fan work

    Just my 2 cents to some great suggestions; Monitor the power supply with a voltmeter before/after your 5min reset fix to see if there's a problem there. It's possible a ps component such as a zener diode is shorting out the supply. Unplugging it causes the capacitor to discharge and...

    Fridge light

    Take a look at the lamp socket. Sometimes a loose contact is enough for the light to go out. I assume you've already tested for continuity looking for bad connections. Provided you understand the risks and trust yourself to working on dangerous voltages: Another thing you can try is putting a...

    Fridge light

    I'm not sure what you mean by "starts good" but it sounds like a bad connection somewhere. Did you check switch under a load? Just testing with a ohm meter doesn't prove its ok.

    Power powerwheels

    A few years back my boy asked me if I could make his powerweels faster. Of course I couldn't say no to him. So I put in a second battery in the front storage compartment and wired in an automotive relay that switches it from factory 12v to a turbodrive 24v. The relay is energized by a...
