B2650 Alternator Output for LED Lights?

That is definitely the dynamo.

It generates ac current and leaves on 2 wires and goes to an external voltage regulator.
This is how my John Deere was setup. I converted it to a 40amp 1 wire.
For the idiot light in the dash and everything to work right it will require some modifications.

I seen some places where kubota sells the upgraded alternator, new belt and wiring harness.

Not sure if it was specially for the 2650 tho

Yes Dan you are right that is a pic of the dynamo. There is an upgrade for the B2650 from Kubota that other members have done. If I remember right it is 40 amp. Search on this site and I will try to find it. I also updated my spool valve build so check it out.

I found the kit number that some of the other members from here and OTT have used. It is B7324 and is 40 amp.

I will have a conversation about this issue with my dealer when my tractor comes in. I can’t believe this is something that needs to be added after the fact and he customer to pay for.
How can a small bx come stock with the 40amp alternator and a premium 50 series B comes with a dynamo. This should be a 40amp minimum from the factory.

That kit includes the same denso 40amp alternator I put on my John Deere 455. It has 2 spades on the back. One is a ignition 12v excitement wire. The other is a negative ground to light up the idiot light in the dash. I made it work easy enough on my 455. But I will see how much the kit is from the dealer

If I remember right, it is around $200.00

Here is a link to a video I made of the alternator upgrade I did on the 455. I made it to try to help other owners of John Deere garden tractors to upgrade for about 80$ instead of 400+ John Deere wanted for the kit. I kind of ramble in the video. It was my first one. And I don’t even think I had a drivers license yet...

If it’s only around 200$ I’ll buy it. Or make the dealer throw it in with the tractor deal. As I haven’t signed anything or actually purchased it yet.

Your picture shows the dynamo,RC. It was the same in my 2009 BX2660 and my 2012 B2620. It is the same one in my new B2650 ROPS. It is rated at 14 amps as far as I know....just like the others. I had put two 55W halogen lamps on the other tractors and they drew 4.5 amps each. The dynamo handled it okay. Some treads of the past discussed replacing the dynamo with an alternator to gain more amps.

When I put light on this B2650, I'll select a couple LED's to gain more light and use less amps. Some have commented that the LED do not create heat and can ice over in bad weather.

Cheers,
