“Fearsome Extreme” Full Wave Rectifier CT90 K0 with 3 Wires


CT90 3 wire in-the-frame with short wires (fits the K0)

  • Yellow: male terminal
  • Red/White: male terminal
  • Pink: male terminal


The earliest CT90 is the K0, which has a 3 wire rectifier. The “missing” 4th wire is a Green ground wire.  Before ordering, inspect your bike and insure it has the 3 wire rectifier.

Jon Pardue designed this for riders who wish to bolt on one last rectifier, then forget about it forever. If you ride one of these bikes like your life depends on it to stay running, then your spirit is captured in this rectifier. This rectifier is built to be water tight, corrosion proof, and nearly bullet proof. Its got the strongest, highest specifications parts I can locate. Low cost is not the object, highest quality is all that matters here.

The wires exit the rectifier at 90 degrees to the bolt hole, just like the OEM Honda part. There are no wires to snag, become unplugged, hang down, dangle, corrode, loosen, weaken, lose grip, or short out on nearby metal components.

These days electrical parts have almost no warranty, no support, and no explanation. We take a different approach from a time long ago.  We have color illustrations to help you assess your bike, to learn what it needs.  If you break this part during normal use, send it back with the story of how you did it, and it gets replaced. It may even make it to our “Wall of Shame” which is an almost empty place.

We make several styles to match various bikes. Inquire for bikes not listed, we add new parts all the time and will gladly make a rectifier for your bike.
