22.2 Load Meter Configuration
Alternatively the shunt can be installed between the alternator output and the main bus in which case it will be the
load meter configuration showing alternator load (positive only). Be sure that the negative side of the shunt is
connected to the main bus in the load meter configuration. There is no alarm.
23. General Fuel Flow Transducer Installation
Use the J4 connector harness 700708 labeled FFSIG (white), FFPWR (red), and FFGND (black). If no previous fuel
flow transducer is installed, install transducer per
The EDM-900/930 receives signal from any installed FloScan Transducer with the following FloScan P/N’s
embossed on to the top of the transducer. The K-Factor is marked on the side of the Transducer and on a white
ticket. Wire per drawing 790744, Route the JPI wires along the existing wiring bundle lacing every foot.
The EDM is approved to work with the following Shadin equivalent PN.

201-A NA
201-B 680501/680600
201-C NA

Before connecting any hoses to the transducer, thoroughly clean them and insure they are free of any loose
material. Never pass air pressure through the transducer or use Teflon tape/pipe cement; damage will
occur. Use only steel fittings supplied never use aluminum fittings on transducer. Remove the transducer cap plugs
only when ready to install the hoses. Note the direction of fuel flow marked on the transducer. Fuel must flow in this
direction. Reverse flow installations will read ½ the required flow. Mount the transducer with the three wires pointing
up. The K-factor is printed on the side of the transducer and on a tag. Write down the K-factor here for future
reference __________.
