Tech Help / Re: DEAD 2013 Zero S, DC/DC Converter Issue????
« on: January 07, 2020, 04:38:03 AM »
It was last year so I'm not totally sure but I think the 4th led was flashing green every two seconds like yours. I was also able to connect to the bms with a serial cable to look at the logs and the bms seemed to think it was fine but the fuse was blown.

I had a similar issue with my 15' fx. One day I turned on the bike and I had no lights or 12v output but the bike ran fine. Next day I found a blown fuse for the dc/dc, replaced it and then no life at all from the bike.  I went through all kinds of testing and troubleshooting, thought it was the mbd like you. Ordered one, installed it and no change. Long story short the dc/dc had failed and ended up blowing the 10a surface mount fuse on the bms board of both of my packs.

Yep after changing the fuse I reinstalled the bms board to the battery and pushed the reset button the bike works perfect on that battery, no error codes. My other bms board has other bad components. A few transistors(Q18, Q20, Q45, Q46, Q47, a zener diode z62 and two coils L1 and L2 are burned so I'm searching for a schematic for the bms if it exists.

I'm able to read the markings on the fuse, diodes and transistors with a microscope and ordered some of them from mouser.com but coils l1 and l2 are not marked. If anyone has a schematic of the board or part numbers or values for l1 and l2 i'd appreciate it.

With the f2 fuse blown I still got pack voltage and 12v from the pins on the battery and to the mbb but when I turned the key on the voltage dropped to 26v and the bike would be dead. The bms status lights were still working and I could connect to the bms with my computer.

It's not the pre-charge fuse as marked in pink on that page but it's the same size and part number. The fuse I replaced is just under the right side of the top black connector plug.

Buy Sell Trade / For Sale: 2015 MBB
« on: February 14, 2019, 08:00:50 PM »
Selling an MBB (Main Bike Board) from my 2015 FX.  I beleive it can be programmed by a dealer to work with any 2015 Zero.

I ordered a new one trying to troubleshoot a problem with my bike that ended up being bms related so it's not needed.

$350 shipped within USA

So it turns out the dc/dc damaged the bms boards in both batteries when it failed. On both there was a blown 10 amp surface mount fuse which I got replacements from mouser and soldered on. One battery is good and the bike works, the other bms has more issues. Does anyone have a schematic for the bms ? Part number is 41-06419.

My MBB was fine so I'll be listing the extra in the for sale section.

Thanks Brian, I found the Sevcon 500 watt dc/dc on ebay for $157.50

Yesterday I found that the 10a smd fuse on both of my BMS boards are bad. Seems the dc/dc took them with it when it died.

Also would add, the dc/dc was bad and is no longer in the system. Trying to figure everything else out before replacing.

Dealer is 5 hrs away, and I'm out of warranty. Somehow my 15' fx has 14' batteries.

Ok so I just received a replacement mbb. Installed it and no change, still no sign of life at all. Voltage on the power in wire to the mbb is 104v then drops to 26v when I turn the key to on. Whats next? BMS

When I try to get the contactor to close like this the bms thinks it is colsing the contactor but its not actually closing(connected to it with obd cable and putty app.) .
