yes it drains even quicker with high beams on its really annoying so much money has been spent to rectify the problem yet its still doing it
its less then .3 when key is off and auto elect checked the current with car off and also with the car running at different rpms and it was all in a good range well above the 12volts which is why its got me stumped as to why it keeps doing it and the other thing it will drain the battery quicker when headlights are turned on
Sounds to me that the battery isn't holding charge.
A battery like that WILL show full charge but will release that charge at a very high rate.
To test if the battery is holding charge,
Charge the battery externally so it shows full charge.
With ignition off and no other accessories on, turn on your head lights, low beam will do and put a volt meter across the battery so you can see the voltage drop.
Now, time how long it takes for the battery to run down and let us know how long it takes to go flat.
Say for example it's a 100 amp hour battery, the battery 'should' be able to take a 100 amp draw for 1 hour.
So @ 50 amps, lasts 2 hours.....25 amps 4 hours....12.5 amps 8 hours and so on........
All this is in an ideal world and times will vary greatly depending on the condition of the battery.
