B7610 Charging system

[tmthunder]

What is the capacity of the stock charging system on my 05' B7610? I see that is has a 20amp circuit for work light provisions and 30amp for the solenoid. Is this a dynamo type system or is this a standard alternator?? Thanks for the help. I could not find any info in the owners manual.

Without seeing the charging unit it's hard to say, but a quick guess would be: if it's painted gray theres a good chance that it's a 14A generator. If the unit is silver or aluminum, it's probably a 40A alternator. I'm thinking that they only come from the factory with the dynamo and the alternator is a dealer added option.

There was a thread on this a year or so ago. It concluded that the generating unit was a dynamo and not a true generator or alternator. As I recall, power is taken off the stator windings and must be rectified like an alternator, but there are no field windings on the rotor such as an alternator would have. Instead the rotor is a permanent magnet.

It's output is rather puny, as I recall. Enough to keep the battery charged and run the OEM lights. Probably around 20 amps, maybe less.

I've not had to get into mine yet, so am weak on the details. Since there's no way to control the field strength of the rotor, the voltage regulator (if it even has one) is not conventional.

Ok I will have to look again as I don't recall the color. I think that it was gray though. If it is in fact only a 14A system why would they run 30 amp circuits.

The battery will provide WAY more than 30 amps......

The dynamo is rated 14 to 15 amps at rated pto rpm.
The alternator is rated to 40 amps.

Theres a very obvious physical difference between them. The dynamo has no cooling fins and it's soild cover is grey. The alternator looks like, well, an automotive alternator.

Thanks for the input I am now thinking more about it and am pretty sure it is original. Is the 40amp alternator upgrade a kit? If so what is the part number and best place to buy?? Thank you!

If it actually has a alternator it's one of the following. If it's a Nippondenso it's either a 30, 40 or 45 AMP. The 30 and 40 AMP Nippondenso's look the same with the + charge wire at the back of the alternator above the 2 terminal connector. The 45 AMP Nippondenso has a large + stud that is on the side of the rear housing and a 2 terminal plug in the back. If it's a MITSUBISHI it's a 30 AMP. They also used a MANDO alternator but I'm not sure what the current rating was on it. I could probably do a little digging in my rebuilders catalogs and find some more info.

If it's a Nippondenso alternator and you can see a part number tag on it here's the Kubota part numbers for the different alternators:

30 AMP Nippondenso Part #'s 16231-64010, 16231-64011, 16231-64012

40 AMP Nippondenso Part #'s 16231-24011, 16241-64010, 16241-64011, 16241-64012

45 AMP Nippondenso Part #'s 16771-64010, 16771-64012

I've seen many posts about this.The upgrade 40 amp alternator kit is available through Kubota's Whole Goods(The salesman)as opposed to the parts dept.The cost seems to be about $200.I've thought it should have been standard practice.Although,the standard dynamo has proven very reliable,as long as you can live with it.

The previous owner mounted 2 lights on the front of the cab and 1 small electric heaters in the cab. I wanted to add a work light on the rear of the cab. I have not tried the heaters to see what type of heat output they have. But I am sure that they would really task the 14amp dynamo. I will call the sales man that I bought from and see what he can do for me on the upgrade kit. Thanks!

Seems like a good OLD thread to work with.

I've a B7610 also and am wanting to get a winch to primarily be used with my trailer and Ford E350 Diesel Maxivan. I'm pretty sure the van will handle most of the electric winches in my price range ( < $1K ). Could the B7610 handle a fairly large winch (wants 650 CCA minimum for winching) briefly? Could I hook it up and operate it for a minute?

thanks
