My 2008 Pilot SE AWD will not start. I replaced the battery and Alternator a week ago. Car ran fine. Now, nothing happens when I try to start it. What could this be?
Thank you for the suggestion. I’m still getting this issue intermittently so I’ll take your advice and check the fuses. Something IS slowly draining the battery.Since OP already replaced the battery and alternator last week I’m guessing there is a parasitic draw on the system. Easiest way to check is to put the multimeter into millivolts DC mode and measure voltages across the fuses. The Pilot needs to be off with no key in the ignition while measuring. Any fuse with a reading out of line with all other measurements points to a current draw on that circuit.
If OP was able to jump start the dead battery, and presumably drive the Pilot around the block, it seems the alternator and cabling & fuse between the alternator and battery positive are functioning. Voltage measurements across the battery, once the battery is charged, would verify this.
OP, you will likely need to charge the battery prior to measuring voltages across the fuses and verifying the charging system.
Intermittent sounds like it could be a poor battery cable connection or corroded cable. Double check the battery connections and also the negative ground connections. Sometimes the stranded copper of the negative cable can corrode and start to break away near the frame connection. The battery terminal clamps can stretch and no longer grip the terminals, even though they look good.Thank you for the suggestion.
