    Re: HV wire

    The glue was barely touched. The short actually carved a path through the PCB.

    The inverter was overdriven by 2V or so. Would that have contributed to the arcing?

        Yes it would have.

            The inverter input should be between 11-12V. Since I am using it in an automotive application, voltage can vary between 11 and 14V. By my calculations, a 5.6Ω ballast resistor should even it out.

                Ugh! More arcing... this time between the black box and the white connector. This high voltage stuff is tricky.

                    kinda sucks not being able to edit entries...

                    So I removed all the carbon, thoroughly cleaned the board with solvent, put on several coats of laquer, and surrounded with silicone, plugged it in and ... instant arcing. Bah!

                    Then I removed ALL the added material down to bare board and leads, plugged it in, and it is completely stable. Nota bene, air is the best dielectric.

                        Lenovo Yoga 710 15ISK, 80U00002US battery cable wire broken.
                        by emeskay
                        We have an Lenovo Yoga 710 15ISK that we use as a secondary laptop. To cut a long story short, around May 2023, while traveling, I connected the laptop into an electrical outlet that was already switched on. Something made a "pfft" sound and the laptop refused to turn on after that. After getting back home, I gave the the laptop for repair to an informal repair person. He replaced the adapter and an internal motherboard part, but after he returned it I noticed that the LCD did not look normal. Essentially, every alternate horizontal line on the screen had gone missing. The laptop was...

                        Vintage fan repair, copper wire question
                        by technicalspecialist
                        I currently have a customer's vintage fan on the work bench to repair.
                        It uses an induction motor with 4 poles. One of the poles is open.
                        I couldn't find the break so i cut off the original wire.
                        I have measured the other poles and the resistance is about 28 ohms per pole and I measured the diameter of the wire with my digital calipers and it is 0.35mm in diameter.

                        I need to work out how much 0.35mm diameter enamelled copper wire i need to order for it to be 28 ohms. I have used this calculator and it says i need 160.35 metres.

                        The enamelled copper...

                        Heater element wire type instead of a fuse when troubleshooting a short circuit DIY
                        by sam_sam_sam
                        I was Ollie today which is a close out / surplus outlet store I do not go in there to often because you find things that you should not be tempted by but that is a another story

                        I saw a small space heater that used a wire type of heater element which I been looking for a while but not really hard mind you but when I saw this I grabbed it I going to go back tomorrow and buy the last one that is like the one I bought today because I need the heater element and the ceramic insulators and more of heat element wire because this one has two different wattage settings one 1300 watts ( tap...

                        1070 GPU. DVI port removed, wire in its place, why? Stuck on low clocks too.
                        by GlenBrim
                        I got this recently as-is. Gigabyte 1070 video card.

                        DVI port is removed. I don't know why.
                        A wire is soldered across two spots where it looks like the DVI port was. I don't know why.

                        I've read of people simply ripping out DVI ports and the rest of the cards still working fine. Never read anything about soldering a wire in there for some reason.

                        The card seems to work fine, except it's stuck in low clock speeds. While starting a game or benchmarking, the clocks may momentarily increase to around where they should be, then goes way back down and stays...

                        New wire for my RDE3340 Whirlpool electric range
                        by wnlewis
                        OK. I got the rocker switch figured out thanks to the good advice on this forum.

                        Now I need to figure out the correct wire to go to the switch from the broiler element and from the oven element.

                        This is a Whirlpool RDE3340 electric range.

                        The common wire on the switch appears to have a high temperature insulating material. I am guessing that both the wire to the broiler and the wire to the oven elements also need relatively high temperature insulation. What do I need to look for? The broiler is rated at about 2400 watts.

                        Where may I find parts...
