Honda 3000is 12vdc plug question.....

[EGAZ]

For those who have a 3000is quiet genny, can/would you do something for me?

I think my 12vdc regulator has died. I want to see what a normal working regulator does.

The last day on deck both 12vdc fan motors & pumps died on my grey water evap. All at the same time, strange..... I discovered that the 12vdc out plug was giving 16vdc on Econo-Mode and as much as 24vdc with Eco-Mode off. (hi idle)

So I would like to know what voltage your's puts out on the 12vdc plug in both Econo-Mode and not. If you could, do it with 'no load' and again with a 12vdc load.

I am not sure the 2000's use the same 12vregulator or if they tap the feed from the same place as the 3000. So unless someone can confirm, the tests need to be on a 3000.

Thanks!

You can Google the schematic. None of the EU series regulate the 12V output. I would not use it.

The 12V winding goes to a full wave rectifier then to DC out with no filter or regulation.
It would be easy and cheap enough to add a voltage regulator. Take a look at https://www.sparkfun.com/tutorials/103 a fairly decent read, look in the comments for selecting capacitors. Select current rating of the components at 120% of fuse size.
If you plan to charge a battery from this you will need a different regulator which would control the charge rate.

OK Ratty, let me translate:

or
DC out on a Honda generator will burn stuff up.

You'll be better off Just buying a 12V regulated power supply and plug it in. You can get something like those table-top power supplies or one of those larger switching power supplies which can supply more amps. I like Meanwell brand, but even the cheaper ones will do fine.

They'll be pretty well regulated, even though there will be some switching noise. If you need something with very clean output (e.g., for audio) you can use a power supply with a linear regulator, but they consume power themselves.

So I am correct in thinking the difference in output is directly related to motor RPM? Which is why I see 16 & 24vdc.

I normally plug into my 12vdc ports on the RMC, which pull from the house batts. But the Playa gremlins made me plug into the Genny 12v ports. Didn't want to troubleshoot the issue at the time. The only other time I've used the genny 12v ports was to quick charge a batt on the quad.

Sure seems strange they didn't tie them into the the genny battery charge circuit.

The 12VDC ports on the Hondas are best forgotten.

It doesn't even have a 12VDC output port.

It has an output port for charging 12V car batteries.

In an emergency you could charge a 12V battery from a honda generator but as a regular thing, unregulated DC will overheat a battery, the plates will buckle and the battery will fail.

My guess is that the exciter current is controlled by the AC section to produce a broad load curve on the AC load ports. What happens in the 12V DC section is proportional, but not controlled. Why they have separate DC windings rather than proper DC-DC converter: cost.
