Title: 2014 Zero SR doesn't work after charging battery to 100%
Post by: rawman on August 12, 2023, 04:05:17 AM
Hi all,

A couple of weeks ago. I charged up my 2014 zero sr to 100% and it wouldn't work. The error light was flashing. After being stuck down the block of my house and turning the motorcycle on and off multiple times for 5-10 minutes, it started fine and I was able to ride off.

I haven't charged it up to 100% since last night. Now the bike doesn't work. The lights are on when the key is in the on position, but the error triangle light is flashing. I tried turning it off and on multiple times and leaving the lights on for a couple hours so the battery can drain a bit, but it's not working at all this time.

Has anyone encountered this issue before?

Could the side stand safety interlock be malfunctioning? You might try bypassing it and to see if that corrects the problem.

Do you know how I can bypass it?

I tried using a magnet.

See if this helps. (https://zeromanual.com/wiki/Kickstand_Switch)

Configure your dash to display fault codes to see what’s up.

After letting the motorcycle sit a couple days, I was able to turn it on and off again without any problems. I rode it about 4 times until it hit 20%.

I thought charging it to 100% was causing the issue, but I charged it up to 80% this morning. Once I took off the charging cable. I received the flashing triangle light again.

This time, I configured the dash to show the error codes.

I'm getting these errors according to https://zeromanual.com/wiki/Gen2/Error_Codes
25 - Contactor Open Warning. This may be appropriate given what safety interlocks are in play.
45 - Kickstand Switch Disable. The kickstand switch safeguard is active
48 - SEVCON Startup Disable. The Sevcon controller startup failed and the resulting safeguard is active.
49 - Contactor Open Disable. Check other error codes and reset by keying the bike off and on.
Check logs later.

My question is, if something is faulty with the kickstand sensor, shouldn't my motorcycle work intermittently? It seems to stop working AFTER i charge the motorcycle for hours.

Now, after a few days, it seems to be functioning properly, turning on and off without any issues.

It appears that this issue occurs only after I have left it charging for a few hours.

After riding it around the block today, the red error triangle and the green light kept flashing back and forth (see video). I'm now suspecting that it's the kickstand sensor that's faulty.

Could it be anything else?
