Most failures and problems are due to wiring errors. Please double check the wiring. (Color code shown is for Xantrex cable)
#1 - DC Power (Black Wire). Start at terminal #1 of the and follow it to the big bolt on the Load side of the shunt. Do not connect this wire to the small screw terminal with the Green shunt sense lead.
#2 Shunt Sense Lead Load Side (Green Wire). This wire connects to the small screw on the Load ("house") side of the shunt. This wire must be a twisted pair with the Orange wire described below. To check this wire start at Link 20 termi- nal #2 and follow it to the small screw on the Load side of the shunt. There should be no other wires connected to this screw.
Note: Now is a good time to check the primary wiring from the shunt to the battery. There should be only one heavy cable from the Battery side of the shunt to the battery. All loads and sources must be connected on the other side of the shunt. Only the shunt may be connected directly to battery negative!
#3 Battery Side of Shunt (Orange Wire). This wire must be a twisted pair with the Green wire described above. To check this wire, start at terminal #3 and follow it to the small screw on the Battery side of the shunt. There should be no other wires connected to this screw.
#4 Voltage Sense Wire (Bat.+) (Blue Wire). From terminal #4 this wire should run to a 2 amp fuse holder, located within 7" of the battery. The other side of the fuse holder should go to the positive (+) battery post.
#5 Link 20 Meter Power (Bat.+) (Red). From terminal #5 this wire should run to a 2 amp fuse holder, located within 7" of the battery. The other side of the fuse holder should go to the positive (+) battery post. This is a separate wire from #4 above (although they go to the same place) because we do not want even the small voltage drop from meter power to affect the Link 20 voltage sense measurement.
#6 Second Battery Voltage Sense (Bat#2+) (Violet). From terminal #6 this wire should run to a 2 amp fuse holder, located within 7" of the second (starting) battery. The other side of the fuse holder should go to the positive (+) battery post.
#7 Battery 2 Shunt Sense Battery Side (Yellow). From terminal #7 this twisted wire runs to the Battery 2 side of the dual shunt.
#8 Battery 2 Shunt Sense Load Side (Brown). From terminal #8 this wire should run the load side of Battery 2.
