Yes, the lights go off when I shut the car off to restart the car.
Having a bit of trouble dealing with the quote feature ?
I cleaned up your posts a bit for you.
I was referring to the "lamp test" that happens when first turned ON.
ALL of them come on and then go out a couple of seconds later.
It sounds like yours are not going out until you turn it completely OFF; and maybe they ALL are not staying ON.
At any rate, you need to have the 12 V battery tested again at a different shop or battery store.
Have them test it a couple of times on a row, waiting a minute or two in between.
How old is the 12 V battery ? If it is 5 years or more old, just replace it.
And check the OTHER ends of the main cables too.
Make sure the new one is fully charged and check the charging voltage after installation.
The sad truth is that if this is not a battery problem, you probably are going to have to wait until the problem gets worse because it seems that there are no "real" mechanics or technicians left these days. If some computer doesn't TELL them what the problem IS......or there is not smoke pouring out somewhere.......or there isn't fluid leaking on the ground.....they have no idea how to LOOK to try and locate an intermittent problem.
