Problem with power outage on dc facing points

So Ive got an inner and outer loop, theyre to be run by separate controllers but to test the wiring ive hooked everything up to one controller, same polarity throughout.
Theres power feed wires either side of those points . Theyre electrofrogs and are separated by isolating joiners.
Problem is when either one of those point are opened while an engines running it stops dead. Doesnt matter if its on the inner or outer loop. Could use some help here with what Ive done wrong? I would have thought feeding power to both sides of the point with isolaters between ( considering 2 controllers) would be correct.

Hi - When using electrofrog points on a continuous run you still need to have IRJs on the main loop on at least the side the frog is on or (preferably) both rails as when the point is switched you get an effective short through the frog.

Ahhh I see what you mean, the powers backfeeding from the other side and causing a short, an insulfrog would have insulated against this by design. Thankyou
