Review on 🟨 Garmin NMEA 2000 Power Isolator 010-11580-00 - Small Size, Yellow by Jeremy Choi

It can be used as a T-connector or flush mount. (See images copied from Google). This is used when you want to isolate two separate backbones or separate the 12V power supply to the device from the power or reverse current devices. For my current use I had to cut the 12v power supply between the standard NMEA 2000 network (T-connection with 12v power) for the Garmin MFD 7610 and 7607, Garmin VHF and Fusion Stereo and also the Yamaha Command Link Lowrance NMEA 2000 isolate connection to hub Yamaha. When initially setting up the Yamaha Lowrance cable (hub Yamaha Command Link to NMEA 2000 connections) it was determined that a 12v NMEA power supply would supply 12v to the Yamaha Command Link sensors and fuel pump when the key was in the off position was. Part I. Lowrance cable 000-0120-37 is used to transmit digital engine data to Garmin 7610 and 7607 displays. It is said to cut the red Lowrance cable (white square connector) to the Yamaha hub cable however If you understand the above then you know you don't want to experiment with the electronics listed if the sub $20 piece is the answer.
