I bought this car 3 months ago. We've had minor issues with it. I had to replace the radiator a month ago, we've got a minor oil leak that will eventually require a replaced head gasket. Other than that, not many issues. However, recently, we went to start the vehicle and got nothing. No lights, no electrical. Now, as we are adept with cars, we did everything we could think of. Jumped it, replaced the battery, etc. We had to replace the alternator belt a few weeks back, and had forgotten to ground the alternator, so we thought that would be the problem. We tried grounding it, no luck. Any ideas?
