if i leave my car sit for longer then 3 days the battery goes dead. I had the battery tested and it check out good. I did an amperage test on the battery and with all the fuses in i'm getting 200 mA and if i pull the fuse for the fan controller it drops down to 80 mA. i tested the controller by it self and its drawing 110 mA by itself. is that enough to drain the battery i three days. the dif controller is new and it didn't work when i got it. I had to send it back to them for repair and now i think its draining my battery. and yes the fans turn off after i cut the car off.

does anybody on here know about parasitic battery drain and how much is exceptable?

I did some more testing and this is what i found

total mA draw is 240 mA with everything connected and plugged in.
Is that to much, i have a few aftermarket electronics: gauges, ebc, electric fan controller, radio (no amps). with all my after market electronics disconnected im getting 20mA draw on battery. so i tested each electronic individually and here's what i came up with.

radio= 7mA
fan controller=110mA
boost glow gauge=60mA
oil pressure glow gauge=40mA
Wide band=0
EBC=0

So what going on here, my glow gauges and my fan controller are draining my battery in 2 to 3 days? A lot of people i know have after market eletcronics in there car, some more then me, and their battery's dont die off as fast as mine. i've been through 4 battery's in the past 6 months do to discharge. I have to remember to go outside and start my car atleast once a day unless i want to jump it off.

you may have your gear wired to a hot wire. as in hot at all times. should only be hot in run.
me personally, anything that high, with car off, after an hour of sitting there, is couse for concern.
let your car sit for a day, check what the battery is at. charge it fully, then let it sit for a day after you unplug the controler, and check the battery again. kinda a ghetto way, but i dont know your tool setup/info base, hope that helps

well, i talked to glowshift gauges today and asked them how many mA does their gauges draw while the cars off. thinking that they wouldn't be able to give me an answer or tell me that they would call me back, the guy answered the question without hesitation. He said that the gauges draw 40mA each while the car is off. Wow that's a lot of mA's for such a little gauge. next i need to get in touch with DIF and see how much mA's their unit is supposed to draw while the car is off.

I had an issue once where I had a relay that was always on regardless of whether or not the key was and it would drain my battery in a couple days. Not sure if that will help you any, but if you had to bypass/add any new relays you might check there. Wiring gremlins suck.
