    M4-ATX battery drain

    I have been doing some reading and have seen others state that even if the M4 is turned off it can drain your battery if a few days if not being driven. I do have a battery maintainer to put on my battery for when I store it so I can have it on there to maintain the battery but is there another way to wire up the M4 so when the car is turned off to stop the drain of power because of the M4. If anyone can help I would greatly appreciate it.

    Cool Two Ways...

    1. Pull the fuse. That is what I currently do.

    2. Wire a relay to switch power on and off to M4. This is what I am in the process of doing (fuse is under the hood).

    I pull the fuses too, over the winter when the PC isn't in the car...
    Make sure your using HARD_OFF option in the settings though too!

    Hey,

    I'm lookin at buying an M4-ATX. Are you guys saying that when you turn ur car off, and the computer shuts down that the M4 is still draining power from the battery?

    are there plans to fix this issue or do we have to come up with a solution on our own (as stated above)?

    Depending on the jumper (hard_off/suspend) settings, it shouldn't draw anything strong enough to drain a car battery...

    My car was doing this...turned out it was the freezing weather and a bad (old) battery...
    Replaced the battery and all is fine again.
    I can't vouch for the OP battery condition or PSU settings...

    I ended up getting a Coleman 5 Watt Solar Panel, and installed it on the
    rear deck and wired it in, seams to work good

    ^Is your window tinted? If so, how well does the solar panel work behind tint?

    I assume that depends on the tint...if it's 40% tint, your losing (upwards) of 60% of available light...
