Taillight fuse blows when ignition turned on

[gpxsrx]

Have a 15 Sr viper no electrical problems till today. Speedo and taillight not working checked fuse and it was blown. Replaced fuse and turn ignition and it blows imeditly what gives. I check one side of fuse block when running no fuse installed the red/white reads 14.30
White/red reads 0.02. I hate electrical where to start. Thanks
I have a launch master installed also but always worked.

here is a start. If you pull the tail relay out and it still blows the fuse then it's before the relay. If it only blows with the relay in place it's the relay or a component after it. Check accessory plug for corrosion or if you wired in a heated shield to the accessory feed (tail light circuit) it could be that.
