Narrative:

During climb through FL250 we noticed a very strong odor that we thought was an electrical fire. We completed the appropriate checklists and then requested the lead flight attendant (flight attendant) to come to the cockpit. Upon entering the cockpit the flight attendant stated 'what's burning' which helped us verify our suspicions of an electrical fire. The odor did diminish some but not completely after running the checklists. We then decided to divert and make an overweight landing.
