Can a 15A fuse increase the battery drain?

I pulled the 15A fuse for the radio from the under-dash box and it actually made the drain INCREASE, but by only 0.01A (to 0.07). I guess I’ll just start pulling everything till it goes away.

What is the current draw on a fuse?

Amplifier: completely removed > NO CHANGE. Everything else is factory stock including radio. 1) Hooked up the meter in series to the negative battery cable. Meter reads 7.18 (20mA/10A scale) current draw. 2) UNDERHOOD – If I pull the: #15 40amp fuse labeled “ Back up, ACC” > the current draw drops to 0.48mA (seems acceptable from what I’ve read).

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).

Where is the drain fuse on an Integra?

I managed to get the drain down to 0.01A by pulling fuse 3 in the under-dash box. Items connected to it are (according to Helms) the Integrated control unit (what is this? gotta look it up in helms…), ceiling light, power antenna motor, and Data link connector (DLC).

How can I tell if my fuses are draining my battery?

Let me know as soon as you get the battery drain ammeter readings on that fuse #24, with the iod fuse out and wait for the modules to go to sleep.

What to do if current draw from am1 Fuse goes away?

AM1 has various loads (at least on the petrol version) and not all ignition switched (e.g. dome lights) – pull their associated fuses to see if the parasitic draw goes away. If you have a current clamp (compact one with DC capability) you can clamp it over various parts of the AM1 feeds to narrow down the offending circuit.

Where can I get an amperage battery drain test?

However, your local public library may have a copy of the manual in the reference section as well. The amperage battery drain test requires disconnecting one of the battery cables. If your car radio or alarm system needs a code to reactivate it after cutting battery power, make sure you know the code to turn it back on.

I pulled the 15A fuse for the radio from the under-dash box and it actually made the drain INCREASE, but by only 0.01A (to 0.07). I guess I’ll just start pulling everything till it goes away.

Is the 15A fuse linked to the under dash box?

The underdash fusebox is *not* linked to that fuse, and the Helms is telling you each and every thing that the fuse is powering… I pulled the 15A fuse for the radio from the under-dash box and it actually made the drain INCREASE, but by only 0.01A (to 0.07).

What’s the current draw on a back up Fuse?

It continuously fluctuates between 0.11A and 0.29A. This is with the car off, keys out of ignition, doors closed, etc. I found out that when I remove the BACK UP fuse (7.5A, but there’s a 10A in its place) from the under-hood fuse box, the fluctuating current draw stops and stabilizes at a constant 0.06A.

How often does a car battery drain out?

I’ve got an inherent drain on my electrical system, killing the battery every 3-5 days if I don’t drive the car. It continuously fluctuates between 0.11A and 0.29A. This is with the car off, keys out of ignition, doors closed, etc.

What does parasitic drain mean on a car battery?

Parasitic drain means something is using power when it should not be, could be a aftermarket alarm/stereo, stuck relay, shorted wire/switch, faulty alternator, etc. I will post a link to show how you can check your vehicle for parasitic draw by pulling fuses and checking amp draw/power with a DVOM. Good luck.

When to start pulling fuses for battery drain?

If it shows 12 volts, you need to start pulling fuses one at a time and watch the volt meter to see when voltage drops to below .03 volts. If after pulling all fuses you have not seen the voltage drop, start pulling relays, then start disconnecting componets where there is current at all times.

How to find the cause of parasitic battery drain?

Luckily, you can usually find the cause of a parasitic draw yourself. Start by connecting a digital multimeter to the negative battery terminal of your vehicle. Then, remove the fuses one at a time while watching for changes in the multimeter’s reading.

How long should Sync module stay on to drain battery?

I just found in my manual (Section 414-01 Battery Drain Check) that the draw should not exceed 50 mA with all electrical accessories off and the vehicle at rest for at least 40 minutes.

Why does my Ford Escape battery keep draining?

So you can’t just determine that the charging system, alternator or v-regulator is functioning fine by measuring voltage at any single point in time. It does need to be checked under various loads and power requirements to ascertain this, so old school methods no longer apply.

Why does my 3 rd battery keep draining?

THis is an intermittent problem. does not always go dead. On my 3 rd battery in less than 6 years. Is the radio tied into the BCM to be draining it. Clicking this will make more experts see the question and we will remind you when it gets answered.
