Overcharging 68Dart...need some short fused help (pun intended:)

Thanks for the reply!
I can't put the mechanical fan on as I had to replace the radiator when it sprung a leak....it was a one step forward, two step back kind of day! The new rad is too thick to fit the fan blades so I went electric.
There's nothing on the back side of the VR bolts but air and tire.
The white wire on the VR feeds ignition (externally fused) to the fan relay with a ground coming from the temperature sender to engage. I pulled the relay when it was overcharging and it didn't change anything. But thanks for making me think on this, not the best setup...I'll ditch that and send it to the fuse box in case it's adding load.
I appreciate your feedback...Thanks!
