Altright so my 2015 sienna starts right up when connected to another car. Multumeter say the battery is getting 13.78 volts while running. However if I turn the car off and try to start it again the car shuts down. No crank, click nothing and all power turns off. The dome lights wont work no headlights. It seems like a seftey feature. If I unhook the battery and reconnect it the dome light head light ac radio etc all work again. But just trying to start it cuts all power to everything. Anyone have any ideas? A short some where? All fuses look good.
