I've got a version 1.0 E100 and the controller is no longer available. I've bought a controller and throttle for a newer version and am wondering if anyone can provide a diagram of how this should be connected. The parts I have bought are:
Thanks. Looking forward to it!
I also attached a PDF copy of this wiring diagram it can be easily printed.
Please let me know if you have any questions.
Sorry for the delay but I finally had time with the kids to try out these new parts along with the diagram. The two scooters are working again! Thanks again! I did have a bit of an issue with the wiring on the switch as I assumed the switch on the drawing was oriented the same way as on the scooter with the off on the botton and the on at the top which resulted in me wiring it backwards with the ground on the wrong side which was causing a dead short. If anyone else is doing this, get the multi meter and measure the contacts on the switch and you want the switching contacts to switch the two red wires on the dwg above. The other is for the light. On my switch, which I believe is the oem switch, the black goes on the top which is the "on" side. The two reds are on the bottom.
If anyone has any questions about this conversion please reply to this post and I will be glad to answer them.
Here is an attached PDF file of the above wiring diagram for easier printing.
That is great! Thanks! I appreciate all your help.
Hello ESP Support,
Your diagram is most informative and exactly what I want to do - change the stock e100 single speed control to variable speed control and remove the kick-start (minimum speed to activate) feature.
1) Will this work with Controller SPD-24120? I prefer this vs the 250W because the motor is only 100W and this 120W controller is smaller and thus more likely to fit in the enclosure area.
2) If it is OK to use SPD-24120, please recommend suitable Connectors to mate with that controller. Hard to tell from the controller picture.
3) The OP chose throttle THR-35. Is this a direct replacement for the e100 or a very easy swap?
The THR-35 throttle is a direct replacement for the original E100 throttle as far as fitting onto the handlebars, however it is a full length twist throttle instead of a half length twist throttle like the original. We have half length twist throttles available that are closer to the original throttle such as our item # THR-93 which is available on this page: http://www.electricscooterparts.com/throttlesstandard.html
If you have any further questions about this modification please let me know.
Wow, thanks for the fantastically fast and detailed responses!
One last question, any chance you can list the dimensions for the SPD-24120 and SPD-24250? The space left in the internal box for the controller is tiny.
Thank you again very much!
Please do not hesitate to let me know if you have any further questions.
I installed the new controller and everything seems to work pretty well with one exception. The brake handle function is reversed. That is, I can only get the throttle to work if the brake handle is activated. If the brake lever is not activated, the motor will not turn when the throttle is engaged. I installed the plug according to the schematic above: yellow to red, black to black. How can I get the behavior switched to the way it supposed to be?
I have recently heard of some Razor E100 electric scooter brake levers having normally on switches instead of normally off switches. This must be the case with your E100 scooter. You could either disconnect the brake lever switch from the controller to disable it, or replace the original brake lever with a new brake lever that has a normally off switch.
I can confirm that mine has the normally on switch. Using a tester, I can see voltage going to the controller until I engage the brake lever. This is the opposite of what the controller needs. Can you recommend an easily replaceable brake lever assembly?
BTW: This was a really fun project and I highly recommend it. The scooter runs beautifully (and I believe more safely) now.
