Battery Drain
When I return from a ride and put my 2017 RTL in the secure barn, for convenience, I always leave the key in the ignition.
Does this cause a small drain on the battery due to the key chip communicating with the D.E.S.S ?
Its not really an issue because I always hook up a battery tender. Just curious. Thanks

Not sure...
Don't know that it does or has cut off but I always remove the key and keep it in a set place on the way to the ryde. I find the computers run their shut down and reset faster and the throttle body as well. I know many around here that do not use battery tenders and leave the key and have never had any drain to the battery. If you use a battery tender you need not worry for sure.....

No. The key is turned on, that energizes the DESS in simplest terms. Key off, no DESS.

For me the set place for the key on the way to the ryde is in the ignition.

No, but there are several inputs to the cluster and vehicle control module that receive power directly from the battery at all times. How much current constantly moves through those two units I have no idea, but there is some. They have volatile memory in them meaning they need power constantly to keep the memory active. Lose power, lose memory. Any Spyder will eventually run a battery down. The older and weaker the battery the quicker that happens. My 2014 RT with the original battery went completely dead a couple of days ago after sitting and not being ridden and not connected to a tender for 10 days.

I never take my key out, it is hot as Hell in our garage and I’ve not had any issues.

I'll have to try that this winter, although it doesn't make sense seeing Bombi has been using DESS in sleds for many years before the Spyders came to market.

On a later models with a 1330 engine like yours. All modules will turn themselves off in less than 3 minutes and draw no power. There is one exception and that is the gauge cluster. Just enough power to keep the clock running. Maximum parasitic draw should be less than 20ma.
The models with 998 engine and fly by wire throttle. The ECM stays active for 40 minutes.

Well that makes no sense at all. Sounds like someone made that up or there happened to be a coincidence of some kind.
