If motor is not running or tach is zero, reduce rotor current to 5% or similar. Just enough to sense if motor / tach starts. Removes chance of cooking rotor.

Most battery packs are set to 14.4 and fine up to 14.6 volts, provided they are fairly well balanced.  You are likely better off using your WS500 and increasing the VBAT setpoint vs relying on an i...

Have been monitoring SOC with the Balmar SG 200 and Kilovault bluetooth app. The Kilovault app  reads consistently higher by 7 to 15 % so I have been switching to internal regulation at the alte...

Don, the WS500 is doing exactly what it is supposed to be doing, so lets look more closely at your battery pack. The problem seems to be with your SOC reading.  Remember that SOC is just a calcu...

After startup at low engine rpm the system goes to bulk and  charges at 20 to 30 amps. When rpm is raised the amps increase as does the voltage to 14.1 volts. That is the VBat set point in line ...

Thanks, its more like an nice to have feature. Lets say you have an client with an installation not working as intended and he sends you the log file. Than this field current data could be us...

Thanks. I hear what you are saying, but it would be nice to be able to control the charger instance yourself. 49 by default, or 0-4 if i want to.   Its not just the Raymarine MDF b...

\"Is this reserved for future HW versions?\"  Yes.  <smile> We have many deployments with two large frame alternators (ala, 24v / 280A large frame Leece Neville alts) and no issues.  The d...

ARG -- NMEA and details... As you found, the WS500 is able to send \'NMEA2000\' like messages via CAN, and uses 127508 as a way to send out some otherwise unavailable details for the alternator,...

Hello. Sorry for the delay in posting this note:  The 15 second is a min time needed; during startup the WS500 monitors the CAN bus looking for other devices on the same battery; as well as if t...

I know that Wakespeed have plans to add some features over the next year but I am not sure if this is one one them.  I would like to have this value reported back as well.  Maybe Al can help with t...

What HW version is able to read the Field Amps? I have tested with V1.0 and also V2.0 straight from Wakespeed and its not able to measure Field Amps. Is this reserved for future HW versions? ...

Trond, I am going to forward this one to Al at Wakespeed for followup. @al-thomason

The WS500 sends NMEA data for Battery Instance 0, that\'s fine. I already have this data from the Cerbo but ok. Then the Charger instance as 49, and this is the data I find most interesting a...

Nice Jan, You got it working. One comment on your last picture. The cable connected to P looks very thin. I can be wrong, because the picture. With a big alternator as this, depend on the ...

Final solution, with 2 holes drilled to have the rotor field connections available externally. For reference: Left wire rotor field (front brush) = positive field, connected to the blue wir...

Nice work Jan!  Excellent MacGyvering. Thanks for sharing your solution.  This really helps the community. @wakespeed-offshore

Hello Jan, This pictures explains a lot. I have seen many alternators, but not this particular model. I dont know where you connect the black(neagtive) and blue(field) as in picture, OR th...

Just an update: everything is working! There was a secondary issue: my fuse in the alternator positive line was blown. Because of this, no voltage was applied on the F+ line and only an induced ...

Ben, Rick, I had the original regulator disconnected and used the connection points of this regulator on the back. The blue wire of the WS500 is connected where the orange wire was connected fro...

Thanks Ben, you beat me by a few minutes :) Jan, to add to Bens reply, this alternator contains additional items within its housing and the back mounted regulator can not just be swapped out as ...

Hello Jan, What I see on your picture, are probably the original wires from the internal regulator.  Maybe your alternator is not for external regulation.  If so it can be modified for external ...

Rick, thank you in advance. I noticed I connected to yellow wire incorrectly to D+ 5 (R terminal). After changing it to the AC-taps and running the engine idle, I only measure 0.25V on the blue wir...

Jan, I looked over the wiring diagram and will need to dig a bit deeper before I can get back to you with a reply.

Some more information, the alternator is a 8SC series. In attachment the wiring diagram (same as posted first, but somewhat clearer).

I\'m having troubles connecting the WS500 harness (positive) to this alternator. Any help would be greatly appreciated. The system is 24V with a battery of 840Ah. The alternator is 100A 24V. I r...

Thanks for the comprehensive response, i did buy my units from Rick and he has been very helpful in the past. When my guys checked on Friday, there was no output from either of the WS-500 uni...

Most probably you have a batterry monitor system in your installation.  You can read the amps that the alternators are charging, this means you don\'t need to wait till Monday to do this test. &...

Hello Phil, do you have any thoughts on the second unit not accepting the 1.2.2 upgrade? The latest firmware is on the wakespeed website for ws500 is 2.4.2. I didnt notice any problem with th...

Hi Ben, do you have any thoughts on the second unit not accepting the 1.2.2 upgrade? yesterday i was able to download the software upgrade from your site, as my tech thought maybe the Wakespe...

Thanks for the prompt response Ben, Please find attached photos of my units with the relevant serial numbers. i\'ll have to wait until Monday to carry out these tests. my electrical guys will...

One more suggestion. If one is not charging, remove Voltage sense fuse and alt+ fuse from both regulators. Do this with engines not running. Swap the  2 ws500 from position. Install the fu...

Hello Phil, I good test for troubleshooting would be to test first both regulators as stand alone. Remove the rj45 cable in between the 2 ws500. Remove at one regulator the alt+ fuse and c...

Good morning Rick and all, i have had two WS-500\'s installed on two Caterpillar 420hp 3126 diesels for over 18 months. i have had some issues where one, or both units would shut down (reduce...

sorry typo it should read: victron VE.Can to NMEA 2000 micro-C male cable https://www.victronenergy.com/accessories/ve-can-to-nmea2000-micro-c-male

Not sure what your CE CAN adapter is and a quick google search didn\'t find it, but your CANBus network is basically a 2 wire daisychain, wiht 2 wires for power and another for the shield.  The ide...

Thanks I appreciate it, I was worried you were going to say something like that! It\'s an annoyance every time I start both engine to have both alarms sounding for 10 seconds I had the old balma...
