Coleman Outfitter 550x alternator capacity

[jmutv]

Hello there!  I am looking at adding some accessories to my 2021 550x like lights and a cab heater.  I was wondering if anyone happens to know what the alternator amperage capacity is?  More specifically I suppose is how much extra capacity above the stock draw is with lights on etc.  I want to be cautious not to draw too much.  Googling for it didn’t return anything useful.

I've never seen a spec published anywhere, maybe someone will chime in.

I doubt theres enough overhead to run an electric heater that puts out enough to be worthwhile. My experience with these types of things is there might be 10-15 extra amps of overhead MAX at idle, quite possibly less. A 100 watt light bar will eat half of that. A 100 watt electric heater would eat the other half and isn't going to heat the cab.

If you feel like experimenting you could keep adding load until the battery voltage is <14V at idle, that will give a good idea of the max limit. Dont forget to turn on the factory lights (35W ea), brake lights (10W ea), turn signals (10W ea), etc as all that has signifigant draw.

I would suggest you go with a heater that uses a heatercore for the heat, the only electrical draw-is from the fan. plenty of heat and You cant see any effect when the fan is running such as dim lights etc. Kits are fairly pricey ($399) for the Ice Crusher I bought, but if you are really handy, you could do an install from generic units on ebay and the like.

Thank you both for your replies!  I didn’t mention in my original post, but this Maradyne Is the heater I purchased: https://www.zoro.com/maradyne-hydronic-heater-12v-2-speed-80-cfm-hf-100012-m/i/G0139120/. I kept going back and forth between it and the next step up: https://www.zoro.com/maradyne-hydronic-heater-12v-2-speed-177-cfm-hf-200012-m/i/G0139087/?recommended=true

I’d like to install with purchasing an enclosure in a few months.  I appreciate the input!

That is basically the same heater I bought as a kit, you will be happy with that. No need to wait for the enclosure, the warm air is nice anytime.

The blower on that heater and a reasonably sized light bar should be fine.

With the Chinese noname light bars the wattages get large quickly. The stock halogen headlights on these UTV's I believe are only 35 watts, so I think like a 40-80 watt light bar would be plenty.
