KilovacRebuildSparrow >> Modifications >> Kilovac Motor Controller Rebuild My Kilovac died recently. It was while a mechanic was driving my Sparrow trying to diagnose suspension problems. I suspect that he applied ample accelerator while moving backward, which is something that can tax any DC series wound motor controller. The Kilovac logic is supposed to guard against this, but it often doesn't. In any case, mine went up in smoke. I chose to have my Kilovac rebuilt rather than just installing a Zilla because I didn't want to heavily modify the control circuitry and because I figured that installing a water cooling system wouldn't be worth the hassle. Rebuilding was somewhat though not all that much cheaper, too. It sent it to Ron Anderson. You can reach him at: Black Sheep Technology 128 Currituck Court Mooresville, N.C. 28117 www.black-sheep.us He was kind enough to send me back some of the smoked parts for my entertainment:  While he was at it, he rebuilt the EVBC control logic box and added 20% more power silicon. When he was done, he re-did the sheet metal enclosure and added a fan so that it has forced-air cooling, rather than passive cooling with fans mounted near by (in some Sparrows.) Here are a couple of pictures of the results.   |
