Info about kill switch?

I was reading the ecomodder wiki and I saw the thing about the kill switch. I thought it was very cool and wanted to install one in my future metro (if I get one). However, in the cons I read
-Battery will run out from heavy use. Drive without power-consuming headlights, or install LEDs. Or alternatively, dont use the switch that much.

How often could I use this mod without draining the car battery too much? I want to know how often people who have this mod use it.

An hyperlink into the Wiki might be appropriate.

I can only speculate from you question that it's an active alternator delete.

Everything I've seen lately is about new cars will have a remote kill switch that is under the control of some power structure somewhere.

There's no way to answer your questions without measurements. How much power does your car draw for the number of accessories you intend to run with the engine off? What is the capacity of your car battery? What do you consider to be excessive wear and tear on the battery?

No free lunches, only tradeoffs.

Personally, I'm more interested in a virtual alternator delete, with smarts to turn on the alternator when voltage drops below some threshold.

I'd consider excessive to be needing a charge every 1-2 weeks or a new battery each year depending on how much gas I'd save.

No power draw. No battery capacity.

No Wiki link.

No pressure though.

I had an engine kill switch on my 06 Canyon. It definitely helped me to get the gas mileage that I was getting. I had some battery problems, and found that it was necessary to put a battery charger on the battery about once per week. The battery charging system is designed to keep the battery properly charged when the alternator is running full time. Part time charging, as with an engine kill switch, will eventually kill the battery. I learned this the hard way.

The kill switch installation is discussed in my 06 Canyon modding thread: https://ecomodder.com/forum/showthre...yon-17070.html. Pay careful attention to the need for fuses in the wiring.

06 Canyon: The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.

22 Maverick: Summer 2022 burned 62.74 gallons in 3145.1 miles for 50.1 MPG. Winter 2023-2024 - 2416.7 miles, 58.66 gallons for 41 MPG.

You would probably want a deep cycle battery if you add a kill switch.

The 4 cylinders don't really pull much on starting. I would shut my civic off at stop lights and crank it back up all the time, and just bump start it on pulse and glides in town. So quarter clutch out till it cranks then push all the way back in and rev match up to like 2000 and put it back into gear.
But cranking the ranger it will kill the battery within like 3-4 cranks. The klr is the same way yet I can crank my cb750 a million times and the battery keeps going.
If you're gonna be doing it just get a volt gauge put in, and probably a deep cycle agm battery.
