I own a 2002 GMC Savanna Explorer van and I have no power at all. The battery is at 100%. What do I need to check?
Cecily, first check all your fuses for the ignition, and starter
Then check your battery ground, and positive cable connections.
Check to see if you have any diagnostic trouble codes present in the
vehicle, that may help with your diagnostics.
that could cause the issue include:
Make sure the
battery has been load tested. Sometimes the battery voltage will read
okay but when you load test it it will drop.
Make sure the battery is checked out properly
