I have a 2014 F150 that has a massive power draw dead battery in less than two days not the alternator trying to figure out what the problem is. I have had all the fuses and relays out. I’ve unplugged the body control module. I’ve unplugged the 4 x 4 trans module and yet there is still a big Christmas tree light up draw when I put the tester light on and the multi meter continues to read zero.

 

When you say massive draw, if your meter can read AMPS, that would be pretty easy to get some idea of just how much

Do you know the maximum your meter can handle ?

Please keep in mind, if the remote is near the vehicle ,the modules cannot go into sleep mode and will manage to drain even a new battery.
I suspect you may not be using your meter properly, which, if that is the case , no big deal we can assist with the proper method.. Easy to do !

 

no idea what it can handle I’ve turned the dial to every setting and still zero

 

Did you get any kind of instruction booklet with the meter ?

 

no it’s my father in-law’s blue point. I’ve looked it up Searched videos put in on all the settings and switch around the plugs in the different terminals still nothing

 

Lets start from a beginning.

What you want to measure is current flow which is compared to water flow and that term is called amperage (AMPS)

To measure that, all current must go through the meter. You need to be careful not to exceed the current carrying capacity of your meter or it will blow a fuse in your meter to protect it and now you cannot use your meter until you replace that SPECIAL fuse.
So all current will go through the meter, you remove the battery positive cable . Using the highest position of most meters,requires using the AMP port with the red test lead connected to the battery positive terminal (+) and the black test lead connected to the cable end you removed. Now all current will go through the meter.
Try that and let us know what reading you get. Make sure nothing in the vehicle is turned on , including the driver;s door IS CLOSED.
The reading you get will tell us how much is being pulled from the battery at this time.
Can you do this ?
Don't forget what I told you about how much the meter can safely handle. Most meters will handle up to10 AMPS. If you are not sure get someone to assist you that is familiar with meters. OK !

 

okay will do I’ll let you know. It’s 7pm in NY here and dark
