Greetings everyone,
Just had trouble starting the car; I noticed it a few weeks ago, but being the slothful person that I am, I replaced the battery in the hopes it wasn't holding charge—a 200 pound error.
I believe I've isolated the problem to a power delivery issue after dragging myself out of bed one evening to conduct some diagnostics.
This is a list of all the symptoms I'm experiencing.
The other day, I left my car running overnight, and it started up again when I got in the morning. I took it for a short trip, and then, just five minutes after turning it off, it still wouldn't start. The voltage on the battery was 12.45 volts.
A second battery can be used to jumpstart the vehicle using the front jump ports.
Analysed voltage: 14.5 volts
Assuming the vehicle is not in sleep mode, the current draw is 70 milliamperes.
After removing the IBS sensor, the push-to-start function still does not work; the relay clicks audibly.
The following readings were recorded when the voltage under load and crank was measured directly from the battery in the boot:
turned off at 12.6 volts
1.25 volts for ignition and 12.2 volts for cranking
for measurements taken at the front jump ports
starting at 11.6 volts with a 0.4 volt cranking electrical system
When I tried to start it with jump leads after transferring the battery from the back boot to the engine block, I heard a clicking sound reminiscent of a machine gun.
I've heard that the positive cable that runs from the battery to the engine compartment is faulty. Conversely, I believe the automobile should have started because the battery was connected to the battery jump starters.
I'd be very grateful for any recommendations or suggestions for items to try.
Even though I enjoy a good puzzle, I am completely overwhelmed by this one. Though
