Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.If you are loosing your light when you try and start the engine then the first thing you need to do is to make sure the battery is fully charged and able to hold a load as well as making sure both cables are clean and tight. Check this for me and post back with the results and we can work from there.
Are you sure the battery test okay, what is the voltage reading at the battery as well as the under hood fuses?
Okay will if the light go out while trying to crank the engine and your sure the battery and the connections to it are okay then you need to trace the source of the loss of power, are you sure there is not a fuse panel on the right side of the engine compartment and if so have you checked all your fuses.
