We are getting close to completing this project, but I have a question.
I'm still a bit confused. Does it look like I have things connect correctly?
The black wire labeled 3 Motor coming out of the female connector goes to the side post on the controller and the red wire goes to the center top post of the controller.
Our bench test went well and everything works. It's time for a road test, but the throttle's wire connector came apart. The wires came out of the connector and I don't know which color goes to which. what do you think?
Do you have any tips on getting a more secure connection with this type of connector?
We do not have a record of how the throttle extension cable was wired and the other end of it is not visible in the photograph, so what I can do for now is show you how the throttle wire colors match up to the controller wire colors. Then the extension cable wire colors will need to be matched between the controller and throttle wire colors.
I see in the photo that the wires were pulled from the connector terminals with enough force to shear most of the copper wire strands in half. This would take quite a bit of force to accomplish and there is not much that can be done to prevent a failure like that under those conditions. If this was caused by the throttle extension cable being too short then we would be glad to make a longer one for you at no extra charge.
That's all I need to know. I'll connect the wires so that it matches your diagram above.
You are welcome. Glad that I could help today. The offer is still on the table of making a longer (or same size) throttle extension cable if needed. Please let us know if there is anything else that we may help you with.
All hooked up and runs perfectly. I'm making some changes to the body so I won't have pix of the whole deal for a while, but the electric motor is excellent. Good speed and enough torque.
Thank you for your guidance on this project. There is no way I could have achieved this without your help.
I also feel that I got a bargain for the money I spent. It really was put together well and your advice was excellent. The government should put you in charge of more things.
Now I want to hook up 12 volt lights and horns. What do I need for that?
There are two unused connectors coming out of the silver junction box.
One is labeled 'Indicator' and one is labeld 'Brake light'.
I supposed these are 36 volts.
We carry 12 Volt DC-DC converters on this page: https://electricscooterparts.com/voltage-converters.html
If you decide to install a DC-DC converter then it will need to have a switch between it and the 36 Volt battery pack. Otherwise if it did not have a switch then it would cause a phantom load on the battery pack which would slowly discharge it when the car was not being used.
Here is a wiring diagram for our DC-DC Voltage converter:
Please let us know if you have any questions.
Maybe for now, I'll use a separate 12 volt battery for the horn, siren and led taillights.
If I use two of your chrome fender mount 36 volt headlights , can they plug into the indicator and brake light connectors coming out of my controller? If not, what would be a good way to wire them into my system?
It looks like the silver box with all of the connectors is called the 'controller'. If that's the controller, what do you call the black unit with ring terminals?
Hello? Is there anybody out there?
