Dear Bill Johns

 We are currently using the following coils for the BQ51050B receiver

1. TDK WR303050-12F5-ID--Data sheet attached for your reference.

2. TDK WR121210-27M8-ID -This is an alternative coil that we are exploring- Data sheet attached.

We are using the following transmitter

RAEGR- ARC400. please find the description of the transmitter from the following link

Currently the Voltage at the RECT pin is zero. We are assuming that there is some EPT error because of which the charging is not turning on. Please find a scope capture showing zero voltage at RECT pin attached
