I had a user programmer and configured it to use a three wire pot, I had bought a 3 wire potentiometer from amazon and used that to test run the motor few months ago before reselling the programmer. So yes it is configured for a three wire pot. Wondering how to use the microswitch though. Worries if the microswitch goes bad, the motor will just spin out of control specially while i am riding it!! Wondering if the microswitch gets connected to the controller somewhere. Couldnt find any wiring schematic of curtis 1238 with the microswitch or the Domino throttle wired to Curtis Controller. Zero use to use Domino throttle for their bikes.

" The throttle is working fine now. There are two green wires for micro-switch that needs to be connected together for the throttle to send proper signal. Else it sends hight throttle signal "

Perhaps you need to stop the world turning. I guess you get what you pay for. And also perhaps the magazine didn't actually test the apps that they reviewed. Obviously I have no answer to your question as I struggle to make a phone call with my smart phone - much less getting an app to work. "

" Can you point me to your documentation for the Domino? And what documentation you're using for wiring the Curtis?

See this:
http://curtisinstruments.com/Uploads...638E_RevC3.pdf

page 6.

Throttle HIGH is pin 15
Throttle WIPER is pin 16
Throttle LOW is pin 18

According to this:
http://electricmotorcycleforum.com/b...p?topic=5252.0

you have White is Throttle low, Black is throttle wiper, and Blue is throttle high.

Have you tested the throttle with a multimeter?


Are you sure you have the motor phases in the right direction? If they're backwards, it won't align with the encoder, and could spin out of control. "

I do not have a programmer handy but it did work with a another potentiometer with a three wire with a high, middle and low connection. I did not try with the domino throttle earlier "

What pins are you wiring the throttle to on the sealed connector on the Curtis?
Pin 15, 16 and 18

If I want to do a 2 wire throttle what pin should i use? Domino has a two wire configuration also. They also have two wire for microswitch. I dont know what that is for though. "

" has any one used the Domino or Magura throttle? I wanted to know the wiring with Curtis 1238. I wired it up yesterday,
- white throttle wire to pot low on curtis controller (Purple and white wire)
- Black throttle wire to pot wiper on curtis controller (Yellow and white wire)
- Light blue throttle wire to pot high on curtis controller (Black and white wire)

When i turned on the switch the motor just went high, even when i twisted the throttle the motor did not slow down. I tried reversing the pot high and pot low wires but still the same. "

" Motor was bought last year off of Hollywood Electric to use on a project but never used. It was pulled from a running FX and appears to be in good condition. It looks like they were planning to ventilate it as it is marked in ink but has no holes. It's still in the box that they sent it in 15x14.5x11 in. 35-40 lbs. that it'll be shipped in. Shipping would be the actual price from Dartmouth Ma. 02748. $660

I might be selling a Sevcon Gen4 from a Govecs scooter too. It's in great shape but is UVW so you'd have to replace the encoder. RLS is the OEM and has an RM28 UVW encoder that is a direct replacement for the stock RM29 sin/cos unit on the motor. $250 shipped to continental United State

" Hi

A bit of progress at least one that is sort of visible...
No, i have not been lazy altogether, but most time has been spend for further researches.
For unlikely being able to source any leaf cells, i guess i will go with Lipos from Alibaba for lack of alternatives...
Think i will also go for a Kelly controller with the Me1115 for lack of anybody around me albe to help programming the svencons..

Anyway, managed to get the main attaching points into relation to each other via simple jigs, at first, and transfered them into CAD.
A milled out leftover wooden panel proved my drawings to be almost perfectly accurate. Just a single bolt needs to be moved by say 0,5mm to fit perfect.
Also included the motor axis as an aproximation and some paper cutouts to get an impression/ feel of how to use the avialible space.
Pics may look as the lower battery would not fit into the fairing but that is just caused by the angle of which the pic was taken.
Next i will cut some foam for simulating a bit more three dimensional..
