Zero S 2011 not starting after a long winter.
« on: April 15, 2017, 05:24:05 AM »

Hello to everyone.

My name is Richard and I have a zero s 2011 here in Canada.
Last fall I used my zero S and sometimes when it was too cold the motorcycle stall and after a few seconds come back alive.
The winter arrived and I stored the bike in a warm place connected to electricity for about 4 months.
Last week I left the warm garage and went to a lil ride of 5 miles when the bike just stalls and I turn off and on again but no more lights in the dash, just heard a click down in the battery and the dash red LED blinks 2 times then 4 times.

Any clue what it can be?

I've  been checked all the fuses and none of them are burned.

Thank you.

Have you checked the owners manual to see what the fault code means?

From what you describe it's either a battery/bms issue or a contactor issue.

Thank you for the answer. The owner manual says contact zero to check BMS

I measured the battery yesterday after buying a multimeter. And before charge it show 55volts after charging I see the same 55volts, I unplugged the 10 pins connection from the battery and measured it in the pin 5 and pin 10.
After replugged this same cables and turned the key on, the errors passed to 2 flashes followed by 1 flash. Turn the key off and on again it goes back to 2 flashes and 4 flashes.  Any clue? Is it correct the  battery generates 55v?.

Thank you

Hello,

the battery fully charged should show 58.8v.

The battery is divided in 7 banks each should be reading 8.4v fully charged. Chances are one or more banks are reading a low voltage (around 6v or less) and the others are reading around 8.4v.

You can check this with your multimeter.

You can try recharge the banks that are reading a low voltage with a rc charger ( like this one https://hobbyking.com/en_us/imax-b6-50w-5a-charger-discharger-1-6-cells-genuine.html?___store=en_us  or better this one http://www.progressiverc.com/icharger-106b.html )

Let us know what you find.
