ok i have parasitic drain from the BTN fuse on the main fuse block. i chased it down and im getting bat voltage drain on the 15A illum, 10A antenna, 7.5A room, 10A hazard, and 20A stop. Now another weird thing is when i remove the 7.5A room fuse my speakers stop working, and kinda make a lil ring to them. Now the radio is still on no sound. If i replace the fuse they come on but emit a slight squeal. the odd thing about that is the audio system is off the 10A antenna fuse. and i go down to other systems in the other lines and im not getting the drain to the brake lights blinkers ect. ect... so im wondering if its the fuse block doing it cause nothing is running when i turn off the car no light nothing. has to be a short to power some were wondering if anyone else has had the similar problem.

 

what is the draw? how much draw? You should get typically a 30-50 mA draw with the doors closed and nothing on. What is yours?

 

im gettting bat voltage draw ill mtry amps agian

 

Okay, let me explain it simpler... think of the electricity as water in a hose.

The voltage is the amount of water available
The amperage is how much water is running through the hose
The wattage is how much water can actually move something.

So by saying a battery voltage draw... well that means nothing.

We need to know how much amperage is being used up. How much amperage is running through the wires.

Or how much is running through the hose... not that the hose is on.

 

ah yeah i understand how it works but its pulling more than 10 amps because it blew my meter fuse

 

with the fuse blown you are no longer completing the circuit so there would be no drain at all then.

And the most common reason for a blown meter fuse is someone that did a clutch or tranny work and they didn't disconnect the reverse switch before dropping the tranny, or pinched the wires when re-installing the tranny.

Either way, with a blow fuse there won't be any current draw coming from that circuit.

 

no my meeter in my dvom no in the car i hooked it up in amps in seris fo that circut with the car off and it poped a 10a fuse

 

10 amps through your DMM is pretty high. What was on in the car when you did the test?

 

i dont know my amm meeter on my dvom is max 10A and it blew that so i dont know exactly how many amps its pulling just more than 10a im shure of
