SOLD Removed the coil from my SV4 so no longer need the controller and coil. $15 shipped. Yes $15 and it works. Use at your own risk and discretion. Suggest using a GFCI plug or at least surge protector. The $15 is really for shipping and a smidge of my time to ship it.rather see this get used versus I toss it. No trades. US only. $15 shipped.
