Blown Fuse in tuner

Lowell787 · Jun 10, 2007, 05:44 PM

I've had my UTEC an Tuner WB02 on the car for like 2 years now. Just a month ago my tuner went blank. I hooked up the other one I had in my Subie and all was cool for another month and then it went out too. I called Trubo XS and they sent me some replacement fuses. All seems to be good now, but I'm concerned that I'm not pulling power off the right place. Any tips on where to pull power off of? I foget the color of the wires where I'm tied in at, but it's the same line I run my radar detector off of and I was puzzled why it worked well for 2 years and then went out....

Smallest fuse ever by the way. On the earlier edition Tuner they super glued those things in. I ripped a connector off the borad just trying to get the fuse out.

Still need some help. What wire to tap for reliable power source??

I've always had the Tuner Pro tapped off the power feed from the Cigarette lighter. If your blowing fuses then you have a short somewhere in the wiring to the sensor, or the sensor itself.

Thanks Jack, I'll check out the existing connections for a potential short, but I cna't imagin what would be causing it. I had heard that the cigarette lighter is not a great power source. I'm also puzzled why my radar detector which is hooked into the same line has not had any issues.
