    Cycle Analyst - still solid choice?

    Yes- this was a second attempt to see if someone had considered utilising torque data from the Garmin Vector system and converting it to provide analogue torque data for the CA3. As regards "waking up" the Vector pedal(s) this is triggered by slight rotation of the unit(s) and not by the "head...

    Cycle Analyst - still solid choice?

    I'm not an electronics expert but would love to find some way of taking the torque output from a Garmin 3S pedal sensor and providing an analogue torque input to the Cycle Analyst 3? I use a Schlumpf MountainDrive so that rules out using any type of bottom bracket sensor. I guess that would need...

    Programming cycle Analyst CA3 for my handcycle

    Feel free to send me a private message and I'll give you contact details. I have a Quattrovelo with e-assist controlled by a CA3 and am quite familiar with the system. I'm in Ware near Hertford.

    Partial screen failure on Satiator 48V unit

    Thanks Amberwolf- it sounds like some rebuilds I did recently on a Mavic Pro Drone- those little ribbons are very fragile!

    Partial screen failure on Satiator 48V unit

    I'm a great fan of the Satiator charger (see my other post re-using it with my Shimano battery) lately the data display on my GC360-4808 has developed a fault on the right side of the screen. I see that spare screen are available as spare parts but would this cure the problem or it it likely to...

    Satiator and Shimano battery compatibility?

    For some time I've been using my Satiator GC360-4808 charger to charge a custom 48v 21Ah battery on my assisted Quattrovelo velomobile, I have appreciated the profile setup which enables me to choose the desired charge level and then forget it with no concern about over-charging. (Most of the...

    ANT+ Powermeter for PAS

    Hi Lee, Just found this-- I hadn't realised that you had previously considered the possibility! Way beyond my capabilities but I think you could definitely make it work! (I could lend you the VectorS kit to work with)

    Garmin Vectors as torque data source for CA3?

    Thanks Amberwolf- your reply makes me realise what a challenge this would be! (although theoretically possible) Actually the Vector system does output torque and cadence separately According to what I've read the cadence output automatically overrides any other source of cadence and the actual...

    Garmin Vectors as torque data source for CA3?

    As previously posted I have a QV (velomobile) with a custom e-assist. (Converted hub motor with Grinfineon /CA3 controls driving a modified Schlumpf (Mountain Drive)bottom bracket and thence to the 11 speed rear cassette) It works superbly but in order to comply "strictly" with the EU rules it...

    Giving a velomobile electric support

    I've now been using the system I described earlier for over a year and 7000+ km. It's proven to be highly reliable and almost imperceptible regarding noise. Although capable of much higher speed/power I normally restrict it (via the Cycle Analyst) to the legal settings of 260W and max assist...

    Destroyed my CA3?

    Finally answered my own questions and learnt a bit in the process! I spent some time following the throttle calibration procedure as detailed in the CA3 instructions- it seems that the parameters were significantly different now that the motor/Grinfineon/CA3 all changed. (Initially I just...

    Destroyed my CA3?

    Finally- my friend visited and we rebuilt the motor and rewired all the leads that exit via the axle. Using one of those Chinese "test boxes" we tested the three motor phases and Hall sensor leads and all seemed OK. The motor seems to run OK "MOST" of the time BUT suffers from a new intermittent...

    Destroyed my CA3?

    Thanks Amberwolf AND Teklektik for your ideas-- I'm sure that you are correct because I see that one of the Halls was replaced earlier (NOT by me!) and seems to be mounted slightly proud of the stator thus possibly rubbing on the rotor magnets. I also note that the leads from the replaced Hall...

    Destroyed my CA3?

    Thanks Amberwolf- I've been away for a bit, so now I'm just getting back to trouble-shooting this problem. I'v got a new CA3 (updated to latest f/w) plus a replacement 25A Grinfineon controller. One of the motor halls has been replaced. Because of the "tricky" cable exit from the Smart Pie I've...

    Destroyed my CA3?

    Further to my previous- (using the methods on the GRIN site) I carefully tested the Hall sensors in the Smart Pie and also the Mosfets in the Grinfineon 25A controller. It seems that one Hall sensor PLUS at least one Mosfet in the controller have failed.(the Mosfet tests are a bit inconclusive...

    Destroyed my CA3?

    Thanks again Tek! I've taken your advice and ordered a new CA3 from the UK sellers Jozztek (not far from Ware "where" I live 30km north of London) and will then do as you suggest and send the dead one to Canada for possible repair. Re the suggested extra cable plugs- actually because of the...

    Destroyed my CA3?

    Further to my previous- I'm weighing up just buying another CA3 against either sending the dead one to Canada for repairs or using your idea of a separate 12V supply . I've removed most of the setup and wiring from the Quattrovelo and also tested the hall sensors in the Smart Pie motor. So far...

    Destroyed my CA3?

    Thanks again- I've emailed info@ebikes.ca to ask about the possible repair of the CA3 and given them the link to our chat here. In addition I've read their excellent troubleshooting guides regarding the testing and repair of the hall sensors. looks like I have some work ahead of me! I do have a...

    Destroyed my CA3?

    I tried your suggestion today- used the LED+ together with a common ground (not LED- this time) The screen lights up with the message "SLOW PMR UP" I assume this means that the MCU is OK? Now I guess I need to try with everything plugged back in and see what happens-- just hope that the Hall...

    Destroyed my CA3?

    Thanks again Amberwolf- I'll try this today and report back. I hadn't thought of using the main earth connection- of course using the LED +/- means I hadn't powered the main "MCU" ??

    Destroyed my CA3?

    Thanks for the reply! I originally powered the main black and red wires via the Controller(from the battery)- using the normal plugs as fitted but with no other wires connected--as I said that gave me battery voltage at the pins shown in the earlier photo. After your reply I tried feeding 12V...

    Destroyed my CA3?

    Another dead CA3?? as I've posted before my Quattrovelo velomobile has a converted Smart Pie motor (fixed and driving through the normal chain and gears) with a Grifineon 25A controller and CA3.(using thumb throttle, wheel speed sensor,motor temp sensor, and analogue aux pot) and It all worked...

    Cycle Analyst V3 preview and first beta release

    I'll monitor the throttle behaviour over the next few days and try and be more detailed-- from earlier observations the throttle continued to work and ws quite controllable- it just ignored the preset limitations! Thanks for the update on the "T" page-- I couldn't find any reference to that...

    Cycle Analyst V3 preview and first beta release

    As I've mentioned elsewhere I have a Smart Pie/Grinfineon 25A/ CA 3 setup on my QuattroVelo (velomobile) . Inputs to the CA3 are thumb throttle, wheel mounted speedometer, and cadence sensor(currently disabled on CA) The throttle is set to pass-thru with limitations of 300W,20A, and 25mph. Since...
