Default Running bike while plugged into battery tender

Hi All. So I have a rattle in the rear of the bike, it goes away when I push on the saddle bag so it's pointing me to the saddle bag supports to start. Rattle sounds like it's coming from inside the fender. Just had rear tire replaced so if dealer took off supports to remove tire, maybe they didn't tighten them. Well anyway I'll have to run the bike in order to hear it and since I won't be going for rides in-between those starts and stops, the battery won't get charged.

So my question is can I run the bike while on the tender so the battery stays charged?

Any advice/experience is appreciated.

Disconnect the tender, and all worries about it end.

Several stops and starts while chasing a rattle will not kill the battery.

But it's not a problem if you run it while it's plugged in. It'll turn itself off thinking the battery is fully charged.

You may want to disconnect the battery tender in case you decide to take a short ride and forget it is connected.

You can always use a rubber mallet to find loose bolts , but like said , leaving your tender plugged in won't hurt anything or not plugging in won't either .

About 8 years ago I had a 68 bronco I kept on the battery tender, one day I just fired it up to circulate the fuel and the battery tender smoked, so that could happen, don't run the chance, just disconnect it before firing it up.

Me thinks you should be okay either way, plugged in or not.

Your charging system specs says it produces so many amps (watts @13V) at 2000 rpm. The excess amps should charge the battery.

I was told by my dealer that I can have the electrics on and listen to the boom and play with the settings with the tender attached and on, bike engine off.

I don't think it would be good to run the engine with it contected. Like most have said you will not use up that much battery energy. Unplug it to be safe,

I’ve always kept the battery tender on all year round, including summer months cause there have been many times when I haven’t been able to ride for several consecutive days. However, I’ve been told by many mechanics and parts counter people not to attempt starting the bike while it’s still plugged into the tender. Just my $.02....
