Guys, I am facing two problems in my civic 2000 that I haven't been able to resolve.
First problem is in the car since it was purchased in 2011, even though the engine was changed in 2017, still the issue is there.
After driving the car for some time like 25-30km, if I turn the car off and start it again. The self won't turn as if the battery is dead, after a few min the car starts as if there was never a problem. I have changed the battery, changed self, still haven't been able to identify the issue.
Second issue is that at night, after driving for an hour or so, every time I press the accelerator the headlights and the meter lights start dimming. Some times the brightness goes down by almost 50%. As soon as I remove my foot from the accelerator everything goes back to normal.
To resolve this, I have added ground wires, but that didn't work, I have added relays, that didn't work either.
