The workbench is getting weird this week. (Yes, that’s my Thunder Laser engraver, I know, I know—it’s not supposed to be a workbench! 😅) This is the first in a series of posts where I break down the science and build a ‘Trophy-Worthy’ high-voltage device. I’ve got steel, copper, aluminum, magnets, switches, some wiring, etc..—but […]
This technical case study details the advanced diagnosis of a persistent, intermittent charging system failure and stalling anomaly on a 2011 Kia Sedona EX (3.5L V6). After multiple failed alternator and battery replacements, the focus shifts to finding elusive high-resistance faults in terminations, grounds, and control relays. The guide outlines a precise diagnostic strategy utilizing Thermal Imaging (TI) and specialized electrical testing to pinpoint the true cause of the chronic electrical failure.
This ia a Soltron Electronic III Display PCB from an Ergoline Soltron Chill XL70 Tanning Bed. This board has obvious thermal defects to the L5973D voltage regulator IC as well as to the trace and the board. It is rumored that this particular board is plagued with this particular issue. The entire board new is […]
