I have just checked the earth from the battery and its ok, battery terminal stays tight even when car is hot, I ran the car up to temp and turned off and re started several times with no problem, I tried to make it fail but nope it was ok, so why does it fail when it feels like it.
Battery is a good 12.5 Volts static, charge rate is good.
Someone must have had the same problem, I read the relay conversion and thought that sounded like my problem but now I have curve balls added which add the element of doubt
I would really love to trust my Supra and drive it but I can't sit and wait up to 90 mins each time I stop
so I am
