IMPORTANT SIGNS OF A DAMAGED GROUND STRAP IN YOUR
BMW
2
The ground strap is the most important element
over the entire BMW car's electrical system.
3
All the electricity that flows throughout your
vehicle goes through the ground strap.
4
The ground strap is the heavy black wire which
connects to the BMW battery's negative terminal.
5
Let us discuss some of the important signs of
having a damaged ground strap in your BMW.
6
BMW WON'T START
This is one of the more obvious signs of a bad
ground strap in your car.
7
When you start your BMW, you will probably hear a
lot of tapping sounds due to a bad ground strap.
8
This is coming from the solenoid of the starter
while it is opening and closing repeatedly.
9
FLICKERING LIGHTS
Due to bad ground strap, the electrical circuit
will receive resistance while delivering power to
the headlights.
10
You can notice the headlights either flickering
or dimming regularly while driving your BMW at
night.
11
In some cases, your ground strap may just be a
little bit loose and will require you to tighten
it securely.
12
DEAD BATTERY
A damaged ground strap cannot deliver a charge to
the battery, expect the battery to die very
quickly.
13
The charging system of the battery depends on the
ground strap.
14
Another reason for a dead battery in your BMW
could be issues with your alternator or the wires.
15
LOW VOLTAGE
Take the help of a digital device to measure the
amount of voltage coming from your battery
terminals.
16
To check for a bad ground strap, run a continuity
test between the battery and the chassis.
17
A voltage reading of 12.6 indicates normal range
but a reading under 11.5 volts indicates a bad
ground strap.
18
Remember
The ground strap is also known as the ground
cable, negative battery cable, or ground wire.
19
The whole electrical system of your vehicle is
dependent on this ground strap to be intact.
20
A bad ground strap will cause a lot of electrical
problems for your BMW.
