XJ900F TID14-37

As an owner of a XJ900F, I have had my share of ignition problems as the bike ages and parts become scarce. I decide to dig deep and rebuild the PCB board of my ignition unit, I have way too many times replaced bits and the PCB board has become a mess. So here is my version, you must use the HA1825 and the HSA-10(B) board from the original. I have not done the mod yet, it will be sometime by the end of 2025 before I rewire the Bike, so “caveat emptor” if you decide to do this yourself from my information here (there might be some errors, who knows yet? it might just be absolutely correct.).

If you want me to make the PCB board available, just leave me a message, I will be getting a few in the next few months or so. Regards Arto.

      Hi Jukka,
      Nice work on your forum, a lot of very interesting articles. Currently I am working on a couple of projects, the first is a Ternary computer, second an interface from Ternary to Binary and third, a complete Energy absorber, one which incrementally stacks energy from four of natures domains – Solar, Heat, Wind and Radio, which are just Octaves from the Universal Energy dissipation from our Sun and the Universe. As these are not primary but secondary Energy flows, they are captured in different transformations that build charge in capacitors to deliver usable charge 24/7. I will release my findings as soon as the protoype is built. Regards Arto.
