I'm looking to here from anyone who has run driver and passenger heated jackets and pants for extended time on a genII. I'm not sure if that is to much of a load on the genII charging system or not.
Heated gear load

Help Support Yamaha FJR Motorcycle Forum:
Are you going to run them wide open? That would be around 300w (2 jackets @ 100w and 2 pants @ 50w). That would be borderline too much load continuous. The bike has around 600w max available but probably draws around 200w for itself.
But, if you run them through a PWM controller at, say 50%, that would bring the effective load to 150w, which is easily doable. Frankly, unless you are running the ice roads, you are unlikely to be running heated gear at 100% for more than a few minutes.

Can we please go riding now ?
Gen II bikes have approximately 250 watts EEC (Excess Electrical Capacity). Some jackets draw about 60 watts on High and some can draw up to 100 Watts. Pants I dont know but are probably similar ...
In any event, go to a good vendor website like warm&safe and check what their gear draws ... Add it together and see where you be ... Also take into consideration that it is rare to run heated gear on 100% (at least good gear) as you will be hotter than heck ...
I would add everything together and assume an average 50% setting and see if you exceed 250 Watts ...
Also consider that the EEC is based on cruising speed where the engine is at 4k or so ... If you are running a full load of heated gear it will almost certainly be drawing down your battery at idle ... So around town you could easily be draining your battery .. Cruising on the highway you should be good to go ...
If you intend to run near capacity, a voltage meter is a must have so you can monitor the system and ensure that you are not drawing the battery down ....

As others have said, you are probably OK if not running near 100%. I typically run my jacket liner to maybe 30% at temperatures above freezing - don't do much riding below that.
You have to consider what other auxiliary loads you are running. Grip heaters? Aux. lighting? (especially if incandescent)
Make sure your battery is in good shape otherwise a short time at low RPM (around town, for example) could leave you with insufficient juice for a restart. You can turn your heated gear way down if in town anyway - not near as much on-time is needed without the wind-chill of 80 mph.

Did some research on the Gerbing site, I'm not sure if I'm reading this right, Max heat for the jacket is 135 degrees@77w and power: 12v dc 6.4 Amp, pants are the same. So still not sure how that breaks down exactly. I also have heated grips, and some led lamps. Tried to find a volt meter locally with no success. Thanks for the help.

Add the Datel volt meter, attach it across the battery terminals for true voltage measurement. Invest in the Carver Fix aftermarket heavy wire harness between the voltage regulator and the battery. Run Heat Trollers for the heated gear. If you have extra lighting up front the Datel will keep you informed when the power draw gets excessive, when to start regulating your farkles draw on the system. And by all means run them all through a well set up auxiliary fuse panel.
Enjoy the heated ride.

One of these will plug right in to your Battery Tender (SAE) lead..... you might be able to find one at a bike shop.

Brodie I have everything running through a Fuzeblock, and rayzerman I was eyeballing those online, think I'll call around and see if any local shops have them.

I want to give a gunny to what Brodie said about looking into what Carver did. I also was loosing voltage and followed what Carver did by getting a hold of Jack at https://roadstercycle.com/ . Huge improvement on my 07.
I would loose both my coat and grips (Honda ST1330), now no issues. On start up all would appear fine but as she warmed up I would loose grips and then the Coat. Now I can have all four of my LED lights running, Coat, grips and have the fan's come on and nothing drops.
One disclaimer, that was when the old fat red head had 85,000 miles on her, Now no issues, none.
Yamaha, flat on thier butt on the early FJR harness! And yes I have Brodies ground harness also. Oh and ignition harness to!
Thank you FJR FOURM. Hopefully good for another 100,000

You'll gain a lot of heat retention by putting a fleece over top of the heated jacket, allowing you to run at a lower setting.
I don't know if the new Gerbings have a temperature control to prevent overheating but I do know of a number of people that have been burned by the older Gerbings.
If you haven't purchased yet, I'd strongly recommend Warm-n-safe over Gerbings. I have Gerbings today but I would replace them with W&S if they failed.
