Been trying to figure how much extra power we have in these Pioneers for accessories.

The Pioneer comes with a 450 watt alternator @ 5000 rpm and the batteries are 14 Ah in the USA and 16 Ah in Canada. The batteries are only for reserve so we can't figure them into the equation.

So 450 watts divide 12 volts = 37.5 amps of available power.

Now that is at 5000 rpm's so I wonder what it produces at an idle?

How much I wonder does the factory setup require? They do say they have lots extra for accessories.

Some of the light bars I am looking at are 120 watt, thats 10 amps alone.

toodeep is there anything from Honda that says how many amps are available for accessories?

Don't you wire the light bar to the battery? It would draw from the battery no?

Which light bar? 120watts sounds SERIOUS.

37.5 amps is alot when you figure it runs all the motor and gauges off around 5 amps. That light bar you should be good with 2 maybe even 3 going at the same time depending on what accessories you run with it. I run a car radio on mine wide open which is 200 watts peak and 160 rms at full blast at night and I havent seen so.much of a flicker which my headlights and leds so I was around 300 watts pulling and no flicker or much of a change in voltage . An easy way to tell if it will hold it is put a voltmeter on your battery and just start hooking up stuff around your house befor you go buy add the watts up and give your self a grace amount like say 12.15 volts constant is still a charge

So 5 amps for motor and computers you think is accurate?

I think I seen where the head lights were 38 watt x 2 would be about 6 amps. So even with the head lights on we should have over 25 amps left. That should be lots. But that is at 5000 rpm, still would like to know what it would be at lower rpm.

With all the accessories we want to put on these we need power nowadays. Stereo, gps, light bars the list goes on and on.

Honda doesn't give any fine details like that to help with things. The biggest draw on the batteries is using a winch a lot (plowing snow especially at night). That's the only time my charging system (on a 4 wheeler) couldn't keep up. I was running extra lights, heated grips, the winch and since it was a Rubicon the motor took extra to run the shift motor.

On a side note I didn't know the Canadian models got the GYZ batteries. They are kind of spendy if we wanted to update to them and didn't have a use for the stock battery..

I've found many items do not draw the amount of amps you expect. Its typically a worst case number. I think you would be looking at 50-60% of the 10 amps due to the lights being rated at 12-24Volts. I'd hook a cheap ammeter in series and verify. Harbor freight sells them for like 5 bucks.
Another option is to dim them if they are super bright, that should also lower the load. Somebody on here showed a dimmer for also 5 bucks. Dang now I'm hungry for a subway. 5 bucks:D

Well thanks guys, I thought it would be easy to add up but there are too many variables. I think I will hold off on the electric heater I was looking at until I see how much the other accessories draw. I never heard much good about them anyway.

The numbers do indicate that we should have enough power for most everything.

I mean I m8ght not be right but I cant see a coil pack that has 18-20 gauge wires running to it pulling more than 4-6 amps then the computer does use much to run through the gauge cluster. Really wanna know how much crank It then disconnect the battery and start adding things on till it dies then tally it up. If you do be sure to give us a thread lol
