Turn signal fuse keeps blowing

Hi, I've encountered a problem. Earlier this week I had to jump my '82 XJ550 because my battery died, and when I did the turn signal circuit fuse blew out. I went and replaced it but it blows everytime I put the key into the on position. There are no frayed wires that I can see and the leads aren't making extra contact with anything except the connectors that they're supposed to be plugged in to. This is really frustrating me since I really don't want to ride it without turn signals. Please help!

Thanks!

 

Pull the connectors on all 4 indicators, put in new fuse, if it doesn't blow, connect one signal at a time untill you find the one that is causing the fault.
If it still blows a fuse with all the indicators disconnected, the fault will be in the swich, loom or the relay.

 

I've had bulbs burn out and actually shorted the hot side to the ground, so you may want to check all the bulbs.
Several years ago, we had a semi trailer that had an electrical problem that nobody could figure out. I removed all the bulbs, one at a time to find that one of them had grounded thru the hot side, blowing the fuse everytime. Hours and hours of labor for just one itty bitty bulb. It's worth a look.
Sometimes the problem lies in just a slight worn out wire insulation right where the wire enters a bulb socket or against the frame where you would never look. Most of the time it's one of those "hit your forhead with the palm of your hand" kinda situations! Good luck.
