Battery went dead, charged it, took it and had it checked, its good. Also tested Alternator and Starter. Got home turned it off and on and it started. Waited 30 minutes and it will not start again. Any idea what to check next?
The most likely fault here is that your battery terminal connectors are dirty or loose. Disconnect them from the battery and clean them and the battery terminals with an abrasive (sand paper, wire brush), then reconnect them.
If this doesn't fix it, you need to check the battery voltage using a voltmeter, both with the ignition off (should be at least 12v) and if possible while trying to start it (should stay above 9v).
If the voltage is below 12 with the ignition off, then the battery is probably faulty.
