WS500 Wiring Harness

$79.95

Wiring harness for WS500 alternator regulator. Includes branches for alternator, panel and battery. Select which configuration you need, either P(Positive excitation) or N(Negative Excitation)Regulators as field windings have two possible field polarities. It is important to know the difference when installing different regulators or testing regulator function. The two types are as follows:a. Positive Polarity. The positive regulator controls a positive excitation voltage. Inside the alternator, one end of the field is connected to the negative polarity. Alternators with this configuration include Bosch, Motorola, Ingram, Sev-Marchal (older models), Silver Bullet, Lestek, Balmar:(1) Polarity Test. To test, use a multimeter on the ohms x 1 range andconnect across the field connection to an unpainted part of the alternator case or negative output terminal. (2) Meter Reading. The reading should be in the range of 3 to 8 ohms. b. Negative Polarity. The negative regulator controls a negative excitation voltage. Inside the alternator, one end of the field is connected to the positive polarity. Alternators with this configuration include Hitachi, Lucas A127, ACR 17-25, and AC5, CAV, Paris-Rhone, new model Sev-Marchal, and Valeo, AC Delco, Mitsubishi: (1) Polarity Test. To test, use a multimeter on the Ohms x 1 range and connect across the field connection to the alternator’s positive terminal. (2) Meter Reading. The reading should be in the range of 3 to 8 Ohms. b. Negative Polarity. The negative regulator controls a negative excitation voltage. Inside the alternator, one end of the field is connected to the positive polarity. Alternators with this configuration include Hitachi, Lucas A127, ACR 17-25, and AC5, CAV, Paris-Rhone, new model Sev-Marchal, and Valeo, AC Delco, Mitsubishi: (1) Polarity Test. To test, use a multimeter on the Ohms x 1 range and connect across the field connection to the alternator’s positive terminal. (2) Meter Reading. The reading should be in the range of 3 to 8 Ohms.

Great service

I faced a few issues but Rick was very helpful and available at all time.

I will definitely recommend this company.

Glad we got you sorted. Thanks for the great review!

worth the wait!

Amazing product & fantastic customer service from Rick @ REC NA / OGM.
Very happy customer!

After having built a lifepo4 battery with a mass produced JBD BMS, I knew I wanted something different when switching to EV. I had heard great things about REC from users of Electric Sailboats on Facebook. I wanted my BMS to be the best quality I could get.

The installation was very straightforward, and greatly simplified by the availability of prebuilt wiring harnesses. The features of the BMS are impressive - while I havent used it yet, the 2 opto outputs are very sophisticated in terms of software control, and I will surely find a use for them.

I'm working on using BMS CAN and fully integrating with Victron multiplus & cerboGX. The fact that Victron lists REC as a known-working integration gave me a lot of confidence in the solution.

I had sent emails (excessive emails!) to REC since January asking for details about the product and release date info. It's a great product, and I'm happy I waited for release.

OGM energy has been very responsive in answering inquiries, and shipped the product sooner than expected. Very pleased!

That's great news Brian. So glad you are happy with the new 2Q BMS. I think REC really hit a home run with this one!!

Fantastic service and an amazing high Quality product.

The setup and installation instructions are of the highest level.
Customer service was amazing; Rick was quick to help out when i inadvertently ordered the wrong harness and gave me a 100% refund.
I would recommend OGM anytime, a great company to do business with

Thanks Adrian. Glad you are up and running. :)

Easy to use

Very easy to use and much easier to program the WS500 than using the native interface via putty. I like the dashboard display which quickly lets you see the impact of your changes.
Looking forward to the CANBus interface as it is annoying to have to take off the front cover of the WS500 to access the USB socket (not a problem with the software more a problem with the physical design of the WS500 - no idea why they don't have a USB socket on the outside of the box!)

Rick the saviour!

I don’t generally leave ratings feedback but Rick at OGM was deserving of special mention. He spent a good deal of time assisting with the design, and procurement of the charging solution for my boat. If it wasn’t for Rick, I’d still be in a mess. Thanks so much, you were an amazing support. I can certainly recommend OGM for their customer service.

Wow, thanks so much for the awesome review. Best of luck getting your boat out of the marina and back on the high seas!
