@Rick When the regulator field wire is removed it doesnt power the alternator.  When the regulator ign feed it off it doesnt have the issue. There is no regulator on the alternator ...

Does the WS500 field get driven to 100% ? If not, try removing the field wire.  Does the alt. still go to 100%? If so, you may have some wiring left over from the internal regulator causing ...

I have just installed my WS500 and it seems the field is always at 100%?Even when the regulator is in the "off state" As soon as the ignition triggers the regulator to be on I can hear the alterna...

I can not specifically answer this as I am in the same position, Ibhave the kit ready but will probably not install it until spring 2024. For reading of the shunt data You need Venus OS V2.93 or n...

Hey,    Just installing my WS500. (replaced a Mastervolt Alpha Pro III with it). It seems far superior with the canbus support. Even with the janky usb port / app. 😅I have installed a s...

Here is what my system looks like.(as a reference. Hopefully nobody finds mistakes :) )

Yep, those are possibilities, but as said I don't want to risk the current avaialability risk of using a data line to actually run anything.  There are wires shown in the diagrams off the igni...

Having the WS500 enabled at a lower voltage would likely require hardware changes.  If it were my installation I would try a simple 5/12V buck boost device like this https://www.electronics-l...

I chased this half the day today.  Got all the wiring done and in place, etc, Wakespeed programmed to my specs. Turn the key, NADA.  Not even a blink out of the Wakespeed. Checked the p...

I wanted to share what I've found as it might be of value to others. My system will have a Load bus and Charge bus, so I need two contactors/switches. Initially I was planning on using the standar...

@Ben  Thanks so much for posting about the TBS - it looks like a great solution which made me go looking some more!(I'll be posting in a new thread about this)  

Sure, it should go across pins 1 and 2.  A 120 ohm 1/4 watt should do the trick. Here is a link to Victron help section that might help too: https://www.victronenergy.com/media/pg/Cerbo_GX/e...

Darryl, If after going through Tine's recommendations you do not find any issues please contact me at support@ogm-energy.com with your current shipping address and we will send you a new current s...

Disconnect everything from the shunt consumption. The current should show about 0.0XX  or negative near zero. I do not see clearly if this is 500A/50mV shunt or 300A/50mV shunt. First check/se...

@Neil did you have any luck solving your issues?  Mine have cropped up again.  I will be carefully checking wiring but it sounds from Edward's experience that this is more likely firmware...

@Edward Its been a long time since I started this thread and that's because I thought my issues had gone away.  Turns out I was wrong.  Should have known that things don't fix themselves...

Hello, Can anyone tell me which resistor and pinout is needed to create my own terminator for the WS500 Thanks. 

The white wire on the Balmar, number 8, connects to the yellow wire on the WS500, number 8. The WS500 is set with the number of poles (12 per the Balmar info) and can then read the alternator rpm. ...

I think the definitions are kind of sketchy sometimes, as they are with a lot of things.  My understanding is that they add phases in clusters of three with the clusters covering 360* so you g...

Hello Everyone,  I have removed a Prestolite 55 alternator and replaced it with a Balmar 6 Series and a WS500.  I am working my way through the documentation of both products. I need s...

There can be many poles, but its still 3 phases. There is really no "middle" phase. They will all give an pulse you can use for pulse to rpm. You can add an diode in series to it. 

That is another vote for the place that I also would normally chosen to get a good pulse signal,  between stator coil output and diode, but I found quite a few people stating to connect at the...

I dont kow the DC Power Engineerng alternators specific.  But, if you open the lid on the back of the alternator you wil see 3 thick wires coming out from the alternator going in to the recti...

I have been spinning my wheels for a couple of weeks trying to get and answer that is correct from Nations and DC Power Engineerng about the proper place to get a stator tach signal for the Wakespe...

In the 2.9.2 firmware update there is a file called bms_1A_Victron_v2_92_2_tasks.bin that should work for you.  If not, then using the Tasks configuration is the way to go You can download it...

Yes, I have downgraded several times while testing with the PC software and RS485 cable, but havent tried it yet with the WiFi module.

No specific problem ... yet. I'm considering updating an existing 2-contactor system from 2.6 , and with all the recent changes to the way a 2-contactor system is handled, I want to be sure I can r...

Yes you can. But what is the problem ? Since 2.9 and the user programmable of CVLC , it is much better to make a nice "float" setting. (Stop charging)

@Nathaniel CPF vs CPB, lol ..  no worries!   Yes,  when the WS500 is in 'Slave' mode, all the CPx values are ignored, except those of CPB.  You can set the CPB values to ...

Is it possible to downgrade firmware in the REC Active BMS?  That is, can I (re)load an older version of firmware over top of a later version if I'm unhappy with the later version?

My current system design uses a two contactor configuration (separate charge and load buses).  I am running with firmware 2.6 on BMS hardware 2.1 . It looks like the recent firmware loads no ...

@Al  A few notes/corrections regarding my post: I mistakenly listed my wakespeed settings as CPF parameters...that was a mistake, so they are programmed correctly as CPB.  I think you p...

Disclaimer -- Al from Wakespeed. What fun!   OK, to step back a bit:  When it comes to temperature of the battery there are perhaps two details to keep in mind:1) Battery Temp may be...

Today I encounted a problem where the wakespeed would not charge under low temperature conditions.  It appears that either the REC is sending a CAN message in error, or the Wakespeed is interp...

Rick,Thanks for the update - things make more senses now!One question - on the updated diagram shouldn't pin4 (Pack+) go to the battery pack side of the contactor?For an actual install should you h...

Thank you, I apprecaite that! Good luck!

I've been having the problem for a while, and now a much larger problem with my REC BMS Q series. I'll try to solve the SD card problem at the same time and let you know.

Life's been busy and I haven't gotten around to trying it. It's a bit inaccessible in my build so I need some time and patience to get to it.

@Eran Did a re-formatted SD card solve your problem? I'm having the same issue.
