Got this beauty with my Agni 95 Reinforced motor and curtis controller, ( Thank you Bikeraider !!! ) rated at 500 amps ! I have no clue how to wire this up yet but it's on the list for this weekend !
Going to either double Anderson PP45's or the bigger PP75, single run of 10 gauge from the backpack is not adequate..
If you haven't tackled this yet, maybe I can save you some research time. When you cut the cable of your shunt-based CA, you will find the same (4) wires (Orange/Orange-white/Blue/Blue-white) used by the high-current CA, and you can use the diagram below to wire it.
To get accurate readings you would want to set the rShunt value in the advanced menu of the CycleAnalyst. Assuming this is a 500A 50mV shunt like I used on the VW Bus, Justin told me: "For a 500A 50mV shunt, you would want to set the RShunt value in the high range mode to 0.1000 mOhm". The standard CA is only good up to 100v, beyond that you need the CA-HC High current model.
Rather than terminating the CA wires directly to the shunt, I would recommend putting a connector in the middle, and if you use a standard CA connector you can use the shunt on any 6-wire Cycleanalyst too. I cut the wires on my Shunt-base CA so I could run them through the channels in TidalForce frames (too small for the actual shunt) and wired a standard 6-wire CycleAnalyst connector between them. Now I can plug the original CA shunt to any Direct-connect CA (CA-DP/DPS), set the rShunt value to 1.399, and viola the 6-wire CA is converted to a inline shunt CA. I can also use my inline shunt CA on any direct-connect controller.
Here is a wiring guide for connecting a shunt to a CA connector, I have a 80-90 CA connectors left if you need some.
CA connector <--> Shunt Wiring
1) Vbatt (red) <--> Orange
2) D gnd (black) <--> Blue-Striped
3) A gnd (blue) <--> Blue
4) Isense (white) <--> Orange Striped
5) Hall (yellow) <--> NULL
6) Ebrake (green) <--> NULL
