No electrical power

Welcome to 2CarPros.

If there is nothing and you are certain the battery is good and the battery terminals are tight and clean, there has to be either a main fuse blown or you lost ground to the battery.

First, make sure the battery is charged. Next, check to make sure the terminals are clean and tight.

If the terminals are clean and tight, the battery is good, then I want you to check 3 specific fuses in the under hood fuse box. I attached a picture to help you find them. I circled the three I need checked.

If the fuses are good, confirm that the ground from the battery to the engine block and body is in good condition, tight, and free of corrosion.

Let me know what you find.
