OFTEN TIMES WHAT we uses to verify the prob is a low amp probe around the B+ WIRE ON THE FP CIRCUIT to map the actual current draw, or to get even more technical we perform a current ramp test with a labscope working in conjunction with a low amp probe, and based on the cleanliness of the signal that is output to the labscope it can be easily verified, but in your case I'm sure you don't have such, so grab a diagram and see what load consumers are on that circuit, if it's just the fp than throw a dart and replace it, most likely you'll solve the issue :)

so which fuse on the diagram is blowing ..eec fuse??
