How does parasitic battery drain work on a Dodge Ram?
How does parasitic battery drain work on a Dodge Ram?
You don’t do an Amp draw across terminals, you use a CT around the positive cable. He is talking about voltage drop as without the truck running and the power being used the battery’s voltage is going down resulting in a dead battery. Click to expand… What he described doing in the quote above is an amp draw test (parasitic drain).
How many amps does a Dodge Ram battery have?
Reading starts and stays as 12.18 amps. Click to expand… You don’t do an Amp draw across terminals, you use a CT around the positive cable. He is talking about voltage drop as without the truck running and the power being used the battery’s voltage is going down resulting in a dead battery.
What’s the current on a Dodge Ram when it is off?
He’s doing an amp draw test, not voltage drop. 12.18 is the current being drawn with the truck off. @Tim C, that is EXTREMELY high for the truck being off (like equivalent to both headlights being on).
Why does my Ram battery drain while driving?
If your battery is draining while driving, it is almost without exception the Ram’s alternator that is causing the problem. If it is you should see the battery or alternator light on, it indicates that the alternator is not creating the necessary voltage to charge the battery. It could be a bad battery, or more likely a bad battery cable too.

How can I tell if my Dodge Ram battery is draining?
You can look for them but as a note you can check the circuit ‘s fuse without taking them out, each fuse has two metal tab (small) you touch to with multimeter, when the voltage is showing you know that the drain circuit and fine what is on the fuse. 10 people found this helpful.

What does parasitic power drain on diesel mean?
Use the search term parasitic power drain or power draw. As said above, have you batteries tested. 5 years on diesel batteries is about max life. Then proceed to do a parasitic drain test. I had the exact same issue, and it wound up being an aftermarket radio i installed staying on in the background.
What causes a Dodge truck battery to go dead?
Finally got my long tube headers on a few weeks ago. Now, my battery goes dead when truck sits one or two days without being driven. I took the truck to get charging system checked and they said battery was bad, so I bought a new Optima Red top. Same thing, goes dead if I don’t drive it everyday.
What to do if your Cummins battery drains?
Load testing is the only way to know and Sears confirmed this in order to get warrantied. So, even if there is something you find draining them then most likely they need replaced anyway. I now hook up a battery tender so I don’t ruin another pair of good batteries.

Why does my Cummins diesel battery drain so quickly?
Because of this, during cold weather, (below 55 deg) it tells the grid heater to cycle. This drains the batteries quite quickly. There was another thread on here awhile back that addressed this issue. I simply disconnected the grid heater from the batteries.
What to do when your diesel battery drains?
I was out camping and had to use two sets of jumper cables to reach from the trailer batteries to the truck – then charge up the bats with the onboard Onan 4000 generator. Took forever to get the bats up to normal operating voltage.
Why does the battery drain after a recharge?
Battery voltage after recharge does not point to a dead cell or battery issue. Anyone have an idea of a system or accessory that will/may hang or not turn off. The frequency points to user problem – I just don’t know where it could be coming from…or what I’m doing?

How long does a Cummins diesel battery last?
Lots of thread regarding parasitic drain testing, and the allowable mA at rest. As said above, have you batteries tested. 5 years on diesel batteries is about max life.
