I replaced my Prius c 12v battery and now my car won’t start in the morning unless I lock and unload my back doors. Help …
Recheck the battery connections. Remember, when you put the terminal clamp over the battery post, tap it downward gently with the back of a screwdriver or something. THEN tighten the clamp. Otherwise you get an iffy connection.
Including the OTHER ends of the main cables. Slamming a door might accomplish the same thing.......IF the frame connection of the negative cable is loose.
I had them check my battery when I replaced my spark plugs and then a few days after it happened again. No power so I open the back right passenger door and the power comes on. No lights on the dash or anything until I open the door. My check hybrid system came on again as well. No other issues going on with the car. I just don’t want to have to pay almost $200 bucks just to get it checked by the dealer
Well pretty much nobody WANTS to do that.......but what are your alternatives ? Do you have a voltmeter.......and know how to use one ?? So far, it doesn't appear that you are hearing the suggestions being made.
