My question is can you run multiple accessories taping into the cigarette lighter aux power. i plan to buy the plug in wire then send that to a small fuse box that i will buy. Where I will attach my lights radio and air pumper. so everything will be on a fuse. my question is. is the wire able to do it?

Others will chime in as I believe there are known areas to pull power from. I’d probably run a fuse block or electronic switch panel directly from the battery IMO…
If the cig aux plug had enough power, I’m assuming you’d take it from the wire going into the plug. Might as take it from the battery?

true but the point is the if i put it from the cigarette lighter it will only draw power if the key is on.

so the battery wont get drained

Right. So power from the battery through a solenoid activated by the cig wire?

key switch activated to cig wire. key off no power to aux electrical add ons

As @YumaYXZ indicated. If you use the auxiliary power (Keyed power outlet), to supply power to a set of relays. And use battery power thru the relays to power the devices, when power thru the key is off then no power will be sent to the devices and there will be no drain on the battery.

This would be the preferred method of powering any devices. Most use combination relay and fuse blocks like the Bussmann.

Since powering multiple devices off just the switched power outlet would exceed the recommended draw for that circuit, powering a switch block direct from the battery is better.

ok that was my question if it would exeed the limitations of the wire.

I installed a second battery under drivers seat with battery isolator run to a small fuse box under hood and then all of my accessories are isolated and drain from second battery. When parked at home goes on to battery tender/charger as with any vehicle that may sit for extended periods.

the cig/aux power port is a tiny wire only rated at 10 amp. That’s not much. Anything powered off that with lights/radio switched accessories etc really needs to be on a relay and then fused separately. You can find a high amp capable relay like 60-100 amp and run power from battery to the relay to power the accessories and control the relay via the cig/aux power input (for key on/off function).

take note though the factory charging system is only powered like 5-8 amps above the basic engine and running component needs (ECU, power steering etc). In fact the manual even tell you to make sure you turn the factory headlights off if you’re using other electrical accessories. This is why. So any added accessories above that will quickly start to deplete the battery faster than it will charge. Hence you will need 2nd battery and/or alternator upgrade. 2nd battery essentially just doubles your time until fully depleted battery; whereas alternator will supply more charging and keep up without any depleted battery charge until you go above the alternator output. In my opinion that’s prob the biggest downfall of the YXZ. Quickly get a few light bars and you’re over the stock charging system.

What you want to do is much like owners of boats want to do. The charging system is pretty limited on these vehicles. I faced this same issue with my boat. The battery is pretty small on these cars. You need a house battery and a start battery. It really gets a bit complicated . You need to do your own homework on this. My fishing boat required major upgrades to run all the electronics.
You need to protect the start battery from all those power hungry devices or you can find yourself......

Dead in the the water.

Running things from a cigarette lighter outlet is not going to work. Unless your charging your phone.

i wont put a second battery i will replace the factory one with a high out put battery then get an alternator if need be .

The existing battery is fine if you add a second alternator.

When I was looking at the two options of 2nd battery vs 2nd alternator. I went with a DLP 2nd alternator. My reasoning was that a 2nd battery was just kicking the can down the road.

A single alternator that is not providing sufficient output to keep up with the load will eventually fail to keep the 2nd battery charged. But a 2nd alternator should be able to keep up with the load and keep the battery charged.

When it comes to cost. A 2nd alternator will run about $500.00. A 2nd battery install run north of $200.00 (everything included). But battery replacement will be accelerated. I estimated that the breakeven point is about 3 years +/-.

CAVEAT: For me the why is more important. I'm not onboard for at least 50 - 75 percent of the time SWMBO is on the trails. So the wife is typically by herself or with friends on the trails for 750 - 1000 miles each year. For that reason, everything must be bullet proof (Why yes, I do wear both a belt and suspenders.... why do you ask...LOL).

I should also mention that I do put a lot of load on the electrical system. In addition to 2 4' lighted whips, radio, intercom, roof lightbar, front lightbar, fog lights, turn signals, rear lightbars, interior lights, rock lights, halo lights, plus all stock lighting and charging a tablet or phone. I also run a spall fan. With all of this load I typically run between 14.1 - 14.3 volts. Yes, it is unrealistic that all of this would be running at the same time. Its not unrealistic that we would be running radio, intercom, roof lightbar, front lightbar, whips, spall fan, installed headlights and rock lights for several hours at night. I would not want this load to run down the battery to the point that the winch would be unable to help her self recover. Or the radio to not work due to insufficient voltage.

I guess the decision of 2nd battery vs 2nd alternator comes down to level of risk. Most can accept a higher level of risk than I can. So, YMMV.

Just my .02 worth. And probably not even worth that much.

Agree with Nate. You get a different benefit by adding alternator vs. more battery. Battery just stores the power so inc battery just inc storage of electrical power. So more juice when the engine is off. If you want to increase the amount of electrical accessories you can run at once, you need alternator. If I was choosing only 1 I’d definitely go the alternator route. Unfortunately it means you get a belt on a pully though

. I’d pay an extra $500-1000 to yamaha if they gave us a OEM alternator without adding an accessory with a belt! Most yxz alternators seem to be 60-70 amp output. I think the stock charger/stator is 25! There’s a post on here that spells it out exactly if you search.

swapping for a higher capacity battery will still be major limit by the physical size of the battery hole. Unless you plan to relocate it, I wouldn’t imagine you’re gonna double the rated battery size in the console. Mines super cramped as is. Just a thought to consider.

While talking about yxz alternators there’s a few to pick from. I chose yamaha brand for 2 reasons. Dealer installed it when new machine with warranty on it. And #2 because It mounts the highest up from the ground, basically opposite the air filter which is above the headers. I think most the others are very low mounting right above the drive shaft/skid plate. We ride alot of muddy/creek crossing trails. So I was afraid of water damage if submerged.

Tubeworks used to have an alternator that was on a Sprague clutch and inside an extended XSMN housing which protected it from the elements. But, that is long gone.

We also ride a lot of mud, rock and deep water trails. While the DLP unit is mounted aligned horizontally with the driveshaft. It provides the most airflow thru the unit. We have not yet had a problem with fording rivers'

(Not one of my pics.. but, close enough).

We do run enough mud and "schmidt" to say that the DLP unit can handle extensive mud and water.

These pics are from last Fall. We did a 13 hour mud run that left about a 1/2" of collected mud and leaves on the engine, underside, etc. It had no effect on the DLP unit, and yes, we have run it this spring and found no ill effects from what we put it thru last fall.

I should probably add that despite being an (unpaid) admin, I do not get any preference or any "favors" from our vendors. I paid full retail for all my DLP products. So, this should not be considered anything more than my personal experiences with DLP products.

A alternator is a far more economical way for sure.

Wow. Awesome first pic. That’s great news to hear it has no prob with so much mud/water! Honestly reading reviews I was torn between DLP and LaRue yxz alternator kits. They both seem very similar and same style. But went with the yammy version as I mentioned above. Dealer installed it.
