I connected all the wires but nothing works apart from the screen which only stays on the first screen. Someone said the controller is not compatible as it is digital.Try greenbikekit.com they have a pin out diagram of a lcd8 and just join the same coloured wires together and blank off the rest.
The two controllers are different size.
This is my original controllerThe two controllers are different size.
The first link is for a normal std Hailong case , it is 15a rated and 6 mosfets.
The second link is for their large big case, it is 22a rated and 9 mosfets so the controller is longer. As already said they are different size so not compatible with each other.
In operation they carry out the exact same functions, both are signwave for 9 wire motor wire.
What you need to do is take stock of the parts you already have, esp the exact battery you have.
Show us a link or pic of every item you have bought along with connectors to save cutting any wires as this isn't always necessary.
So that you don't waste more money on buying wrong items, we can advise and give you a link to but the correct items if any are needed.
Impatience and inability to listen/read advice will get you know where bar wasting money and make you angry, possibly becoming disillusioned.
Many of us have made up individual kits from components without issues, just a case of selecting and buying compatible items.
Brown is for lamp/ligth negative .I bought this https://www.amazon.co.uk/dp/B07KWYXPRL/ref=pe_3187911_189395841_TE_3p_dp_1
Hooked the wires up red, black, blue, green yellow. But there was a brown which did not match the white on the controller. Everything lit up and worked when I pressed the buttons but the battery did not kick in when I tried it.
Well, I was just desperate and it was cheap and was also recommended here in earlier post by Wheeliepete so. Actually, you know more than the God damn kit shop in Hong Kong. If you look on Amazon seller info page it says fits most ebikes. OF course they would say that to make salesBrown is for lamp/ligth negative .
The led 790 display is analogue and not digital so not KT compatible AFAICT, it is a Kingmeter display and they are Luishi compatible.
Is the PAS wired up in the correct sequnce ?Hi guys I changed my controller and display on my Viking MT Tobin I got the 4 into 1 cable adapter and the display Lights up and I can adjust the speed setting but I am not getting any assistance when I pedal do I need to fit a throttle to plug into the spare wire ? I bought this controller https://www.amazon.co.uk/dp/B07K9VZP3K/ref=pe_3187911_185740111_TE_item
Hi I kept the original PAS it has the same 3 wire orange plug so I was hoping that it would work with the new controller, I am thinking that I should have bought a new PAS as well but should I buy a thumb throttle as well or will it work without the throttle ?Is the PAS wired up in the correct sequnce ?
Hi sorry for the delay but the wiring is the same on both controllers black red and white going to the same position in the julie waterproof connector are you sure it doesn't need a thumb throttle to complete the circuit ? I guess it could be a faulty PAS ? As the new controller is KT do I need to change the PAS to a KT compatible one ?Thumb throttle is separate programming so independent.
Tell us the three wire colours from the controller and PAS or show us a pic of the connection, likely the wire sequence is wrong. 5v to 5v, Gnd to Gnd & Sig to Sig.
The throttles always work independently from the pedal sensor, and are optional. Try pedalling backwards to see if that works.Hi sorry for the delay but the wiring is the same on both controllers black red and white going to the same position in the julie waterproof connector are you sure it doesn't need a thumb throttle to complete the circuit ?
