I have added a set of hard bags and tour pack to my wifes 2007 Heritage.
I also have added a J&M 2003 CB, as well as security and siren system.

Currently there are no lights on the tourpack or bags. I am thinking of adding either brake lights or running lights to either the Tour pack or the Saddlebags. Wondering has much amperage draw I have to work with on a stock Heritage and battery.

I assume LEDs' would be less draw. Any ideas will be appreciated. Can I increase the amperage with a larger battery and will it fit? Thank you in advance.

 

The amperage draw of anything you add to her bike won't really matter as far as her battery is concerned unless the lights you add to her tour pack or the radio is left on while the bike is shut off. That all depends on how it's wired of course. I already know, like you said that led lights don't draw hardly any amps so I guess your main concern is how many amps the radio draws. Assuming the radio will be on when the bike is off.

 

The radio is wired through the switch so when the bike is ogg so is the radio.
I see your point though that when the bike is running there is enough amperage to run all accessories. Thanks

 

You should have enough power - the Ultras use all those lights as stock. It's not the battery that determines how much stuff you can power, it's the output of the alternator/regulator. Yours should be the same as that in the Ultra. LEDs use almost no current, so you can add as many of them as you please.

 

Same Question, different, What is the output on my Ultra Classic? I want to add Heated Garments and Heated Grips?
