    Default Anyone tried the sword repair procedure on bruno's site?

    Looks like there's a way to fix a bad blower sword.

    Anyone tried it? I'd rather do that vs. spend $140 for a rebuilt one. However, I don't want to mess it up and a) have to buy one and b)be out a usable core.

    I did the sword repair using the info on Bruno's site. Before the repair, I had speed 4 only, and the motor sounded like it was dying, speed fluctuation, lots of noise. After the sword repair, it still only had speed 4, but the motor sounded fine (??!!!). I then removed the IHKR from in front of the heater box, and found corrosion on the pins on the top LH white connector. After I cleaned that up, the system worked correctly.

    Default Mine works occasionally at the lower speeds...

    90% of the time, I only get speed 4 but sometime the other speeds will work.

    I wonder if this is the mosfet problem or the problem Shogun outlines?

    Good tip on checking the connections too.

    I also had the classic sword problems - blower only working on high, intermittent at other times. Pulled the sword, soldered all the suspect joints ......... Maybe I'm just a klutz because then nothing worked at all. I have no idea whether I may have overheated some of the electronic bits or what. Anyway, I ended up buying one off Ebay, USD$100 with a 2 year warranty. Works fine. I am now practicing my soldering skills on other stuff .......

    The Pundit (Shogun) fix is fantastic and cannot harm your sword, so try it first.
    I found after a few months that my soldering wasn't up to scratch so I removed it and got an auto-electrician mate to solder it properly - wonderful.

    I didn't try that one, was worried about the same issue as you. What I did do was pull the sword and clean it with alcohol pads. After that it worked fine for about a year before I ended up buying a used one off ebay for $100 and a 2 yr warranty much like someone else said.
