Power draw
Ok, since I posted my last thread, asking about a fuse box diagram, I went out and did a little more diagnostic work on my '88 F150. With the fuse out, I now have no turn signals, but I do have hazards. My question is now that I think I have found the circut that is my power draw ( the turn signals ), how do I find out what is wrong to cause the draw? Any ideas? Please let me know, thanks T

Unplug stuff till the drow goes away, as you know you do have to find everything that is on the circuit. Once you know everything thats on it, id set a meter up on the batt, and unplug stuff, like the turn sig switch and see if it goes away. If not plug it back in, and unplug something else, lets say headlight switch. Then if the amps drop down you know the switch is messed up.
