castle ice 240hv esc question

[ls1fst98]

I'm using two in a cat build. Power them up individually, they operate perfectly. I plug them into my y connector and try to power both up, only one will spin up, other one has a constant red flashing led from under the heat shrink. Anyone have any advice? Thanks in advance.

I don't recall if the older 240HV's had BEC's, but my first suggestion would be to remove the middle red wire from both controllers going into the Y-harness and use a separate receiver battery to power up the receiver. Retest.

They do not have a built in bec. I'm having to use rx battery. I've tried 4 different rx battery packs. Calibrated each one independent then plugged them to the y. Unless I'm Missing Something.
