Zero Motorcycles Forum | 2013+ / Re: SR/F front pulley movement

Mine looked very similar to yours. The damage was to the pulley, not the shaft. With the new pulley fitted there was no freeplay

Zero Motorcycles Forum | 2013+ / Re: SR/F front pulley movement
« on: March 21, 2026, 04:13:34 PM »
I had the same problem with my 2020 SR/S. The splines on the inside of the pully are too soft and wear, allowing the pully to rattle when not under load. Everything sounds fine when accelerating or decelerating, as you've taken up the freeplay in the pully rotation. Zero upgraded the pully. I don't have the new part number handy, but you should find it online at any of the major dealers.

Jaime - I don't have a copy of the spec, but I think the minimum voltage changed to 50V a few years back.

Zero Motorcycles Forum | 2013+ / Re: The 12v battery when charging the main battery?
« on: December 28, 2025, 12:00:10 AM »
Yes. As MVetter said, whenever the 12V lines are active, the DC-DC converter is converting main battery voltage to 12V and charging the 12V battery. If the dash is on, the 12V lines are active.

Zero Motorcycles Forum | 2013+ / 2023 DSR/X Recall, Loss of Drive Power
« on: December 15, 2025, 07:26:57 PM »
Zero has submitted paperwork to NHTSA initiating subject recall. It seems the motor controller manufacturer used high resistance fasteners on the bus bar that can cause an overvoltage and shutdown. Attached is Zero's Part 573 Safety Recall Report. Note on page 4 that owner notification will not begin until January 9 next year.

« on: November 20, 2025, 05:38:34 PM »
It's not a problem with just the Zero app. I have a new Samsung tablet and have the same issue with several apps. My soultion was to go to Settings > Display > Navigation bar and select Swipe gestures. The problem is Samsung's,not Zero's.

Zero Motorcycles Forum | 2013+ / Firmware Release Notes, MBB V42 and V43
« on: November 13, 2025, 08:00:51 PM »
MBB firmware V43 was recently released, but the Zero website only has release notes through V41. After an Email and phone call to Zero, I received the following:
MBB V42
• Enhanced key switch fault detection and handling.
• Improved vehicle behavior when key switch input is lost during operation.
• Added safety interlocks for OTA updates.
• Maintained lighting and MBB operation during key switch faults.
MBB V43, BMU V18
• Fix: Resolved behavior that would cause a false Isolation fault during charging.
• Fix: Resolved behavior that would block the ability to commission the motor with DIAG4Zero after replacing the motor controller.

Sorry Peter. I tracked those numbers down over 2 years ago and don't remember the source.

If the connectors are the same as on my 2020 SR/S, they're made by Molex. The plastic housings are part numbers 03-09-1011 and 03-09-2011. The male pins are part number 02-09-2103, and the female pins are part number 02-09-1104.

General Discussion / Re: New CA vehicle purchase processing fee increase
« on: June 12, 2025, 02:27:51 AM »
Upon reading the article linked to by the OP I see that the law allows dealers to charge more, but does not require it. And the money goes to the dealers, not the state.

Zero Motorcycles Forum | 2013+ / Re: Ending (granny) charging ?
« on: April 25, 2025, 04:21:39 PM »
You need to look at the spec for level 1 and 2 charging. The spec requires charging to stop when you depress the release button on the plug. As Jepe stated, the control pins in the plug are the shortest and disconnect first, also interrupting charging. And the ground pin in the plug is he longest, and disconnects last, as a final precaution against arcing.
