trying to figure out electrical issue in a T2210. The #6 fuse blows as soon as the key is turned on. 6 is for the aux lights and aux power( cigarette light). All the wiring looks fine. No damage. If the 11 relay is bad, will it blow the fuse immediately? 11 is for aux work lights. My lights and turn signals work fine. But nothing on the dash. Thanks again!
Blown fuse #6 aux power could a bad relay cause this

Try pulling the relay and see if the fuse still blows. If the coil in a relay is shorted it can blow a fuse but it would be very rare for a coil to short. If the circuit controlled by the relay has a short that could cause a problem as well when the relay is energized.
Thank you, will try that later this week!
Have narrowed it down to these wires. When not plugged in, fuse stays good. Plug it in, instantaneously blows the #6 fuse. Any help is more appreciated!

If you've narrowed the issue down to those wires all you have to do is find out where they go. They may go to a shorted component or insulation may have rubbed off at some point allowing a short to ground. It is also possible a rodent has been chewing on them or eaten the insulation in one area. Some manufacturers use a vegetable based insulation on their wires.
