Ok, so I have a 2011 polaris ranger 400. I have a winch, radio and had one 24" led light on it. Havent had a problem in over 4 years. I wanted to add additional LED lighting to it. So I add a 43" to the front, and a 7" backup LED to the back. With all the lights on, i'm blowing a 10amp fuse. Take it the dealership and they say I'm frying the charging system on the motor. They mentioned running a parrallel charging system, but then say its not available. Does anybody have a clue on this. . . dont want to fry my system, but I do like my lights!

Question on LED lights on Polaris Ranger 400
What are the wattages of all the lights? The length is irrelevant.
Also - what is the output capacity of your alternator?

The total light amp output according to the manufacture is 9amps, they said my alternator was pushing 12-15 amps. . .Comment

Add another battery for your lights and use an isolator to separate them.Comment

Do you have any unused circuits on your fuse panel for accessories? If you add a 9AMP light to a 10AMP circuit that already has a winch, radio and another light on it then you are going to overload the circuit and pop the 10 AMP fuse.Comment

Amazon etc. A quick Google has a kit on sidebysidestufd.com for 90 bucks. I'm sure there's cheaperOriginally posted by slayer View Post
The isolator will allow you to have a battery just for your accessories. The stator will maintain cranking battery first then extra battery. The second battery you could wire each light too and they can have own circuitComment

An isolator will allow 2 batteries to charge at the same time, and you isolate your starting battery (factory) and put your lights and winch (non critical stuff) on the auxiliary battery.
You can find a kit on Amazon, I just pulled one up for $110

I would add a power distribution unit off of the aux battery and wire goodies from there.
Adding a second battery is great, but that won't increase your charging capacity. You will be consuming power faster than your systems can make it. Eventually the aux battery will die on you if out all night.
My next move, would be to look at upgrading the factory alternator to a common automotive type. Chevy used the Delco 10 and 12si for years. Stock they will put out about 80 amps, but are easily built to give 130. You may also look at alternators from small import cars for a more compact unit, but remember that the charging ability will likely be limited.
A bigger alternator will mean new brackets and belt for your machine. It will also be more load on the engine, so keep that in mind when moving forward.

If you do put an aftermarket alternator on and a lot more lights, don't turn everything on all at once! I just had 2 100 watt Hella lights on my old Geo Metro and it would nearly stall the motor when I turned the lights on!
I'd do an isolator first but look at getting a new larger alternator in the near future. You can still use the battery isolator with an upgraded alternator.Comment

Thanks guys! I don't use the lights all that often and definite don't need to have them all on at the same time. They've told me that once it's running I can run one light at a time with very minimal issue. My plan is to probably move forward with an isolator and a secondary battery
