Hello,
I am in need of classic mustang mechanic in Orange County California. Near Irvine.
Issue , no power. I see door light no working assuming no power.

battery is new a month old, solenoid new, replaced by mechanic. Got car back today, was able to start and drive to test new disc brakes. Tried couple of hrs later and it won’t start at all.

I will appreciate any suggestions , help I can get.
