I rode my MAC motor in a light rain / drizzle for about 12 miles. It worked fine for the next few days, about another 30 miles, then it started to run rough and turned off after a few seconds. It was definitely a hall sensor issue, but I had not rearranged the connectors, so I presumed a bad...

I have a CA v3 and a geared hub motor, no clutch. Of course I can get Electronic Freewheeling if I got the Phaserunner controller. But I have several good Infineons all wired for the CA. Does the CA alone allow for Electronic Freewheeling? I am thinking there may be a firmware version needed for...

I just bought the Eunorau. It was 8T. But it is clutchless. I am double checking with them that that is not a mistake, just to be sure. Their description does not say anything about a clutch, but I would think the clutch would be the default. Cable exits at the housing, not the axle end. The...

I have a new Infineon controller - complete with 9 IRFB4110 Mosfets, 100V capacitor, and beefed up traces on the board. It is has the programming JST-SM connector. I took a pass at programming it, but the driver for the interface does not like windows 11, then the usb connector for the interface...

On my classic freewheeling drivetrain, I don't think I can produce enough torque to get the assist to kick in by backpedaling. I never knew backpedaling was a way to turn off the assist. It would be a nice feature, but I never consciously used that. And don't have regen (maybe if I got a GMAC...

Changing to a 1 wire and 5v=forward got it working for both torque and cadence, thanks so much! I am not sure what benefit you get from having a direction signal now that I have it working. I asked the manufacturer about the change in direction signal (no response yet, I just asked them), and I...

I hooked up the old BB as you suggested. It appears that the new BB handles the direction signal differently. The old one toggles the direction signal as you pedal. The new one only toggles on a change in direction: i.e., as long as you are pedaling forward, d arrow displays up and stays that...

I was hoping to find a bad setting, but nothing yet. I also updated to a newer version of firmware than I was using with the old Sempu. I am running 15b6 now. I can't remember my old setting. Installing the new version cleared out some settings, I was hoping that was the culprit, but I don't see...

Amberwolf, BTW, thanks for the help. In the diag screen, I see no change in voltages as I apply pressure to the pedals, but I do see that in the PAS set up screen. I have a regular throttle installed with .87-4.25V input range, mapped to 1.3-4v output. The diag screen lets you follow that...

What I have is this https://www.aliexpress.us/item/2251832780999752.html Good idea to try Cadance only, what the CA calls "Basic PAS". Still nothing, unfortunately. I am figuring it out a little better. This is actually a 2 wire type. As I pedal forward, the D icon points up on the CA, and as...

Status: still not working, even after trying 24 poles. The poles are registering on the CA, too.

I have been happily using a Sempu torque-sensing bottom bracket hooked up to a Cycle Analyst, but the BB spindle rounded out and it is time for a replacement. Hoping to get a plug-and-play replacement, I got a Sempu BB on Aliexpress, which looks identical to my dead one. But Sempu upped the pole...

I captured on video how power cuts out intermittently. The geared MAC motor does make a grinding sound at low power when power drops out. So maybe a bad clutch confuses the controller? I am not sure, but this is what it looks like. The thumb throttle starts the motor but as I hold the throttle...

Thanks E-HP, and ugh! It was the infineon jumper that was limiting power. It makes total sense and I am sorry for troubling everyone over a simple mistake of mine. I am still sorting #1 and #2.
