    BBSHD Error?

    Thanks @alfantastic, you were right! I had the magnets too far away from the sensor. I will need to do some research to see how others are using their hydraulic cutoff sensors. Thanks again!

    BBSHD Error?

    Hi All, I just completed my install of my new BBSHD on my Specialized RockHopper! Super excited to ride it, but I am having an error on the C965 display and nothing works other than the display coming on. To the right of the PAS level there is a exclamation with a circle around it. I have...

    Hi all, I just received a 50v - 24.8 aH battery pack from Paul at em3ev.com. What LVC should I use on my CA? Thanks in advance!

    ebrake, 3 speed switch, and cruise issues on MAC

    The numbers in the chart worked and was able to get 33%, 66%, and 99%. Since the voltages are incorrect for the switch I will contact grin technologies and let them know. The voltages for my other switches from em3ev are correct - 1.60v, 2.42v, and 4.99v. Thanks for your help.

    ebrake, 3 speed switch, and cruise issues on MAC

    Thanks for the chart. I will try this in a while. No the switch is from grintechnologies.com straight from the package. I didn't change the wiring.

    ebrake, 3 speed switch, and cruise issues on MAC

    Its been a few days but finally got everything back together. I installed the 3 position switch and throttle control from ebikes.ca. I am still confused by the 3 position switch. I have tried selecting the Aux -> Scale Limit to Amps and Power with no luck. Now when I put in values from the...

    ebrake, 3 speed switch, and cruise issues on MAC

    I was able to put in the percentages for all 3 positions of the switch but the bike was able to to go to max power in all 3 positions. While I was out on my ride last night I was on a rough road and heard something break. The Axiom rack holding my SLA batteries bent on one side and broke on...

    ebrake, 3 speed switch, and cruise issues on MAC

    So I checked the settings again reviewed in "Appendix E. Configurable Aux Pot 3-Position Switch Using Fixed Resistors" in the guide as outlined in step 7. Changed to different percentages to see if anything would work. Did this on all three positions of the switch. Still no luck.... I...

    ebrake, 3 speed switch, and cruise issues on MAC

    Thanks all for the help. It is very helpful. I have ordered a crimper and connectors from ebike.ca to wire the brakes into the CA. It makes sense the auto cruise isn't working properly and to have the CA control as much as possible. I had another ES user send me their CA settings to try to...

    ebrake, 3 speed switch, and cruise issues on MAC

    The brakes connect to the controller. Yes, the brakes are from the em3ev kit.

    ebrake, 3 speed switch, and cruise issues on MAC

    Hi all, I just got my first ebike up and going but having a few issues. It is a MAC motor, 12 FET Infineon controller, and a CA v3. I am hoping the issues are all related... or at least 2 of them. First, the ebrakes. When I use the left brake it will disengage the throttle. Not the case on...

    increasing voltage to 48v on MAC motor

    Hi all, I apologize in advance if this seems question seems dumb... I just put together my new MAC motor and took the test drive with a 36v configuration with SLA batteries. I was very impressed and was able to get 23.9 mph out of it. But ideally I would like to use (4) 12v 9ah SLA batteries...
