Tried starting the Honda Passport yesterday morning and something popped under the hood while it was turning over. It wouldn't start. Tried it again and something popped again and then lost the electric. Took battery out and had it tested and it was good. Cleaned the terminals, re-installed it and it started like normal. Charging very well.

This evening, it turned over but wouldn't start again. Soon lost the electric again. Heard a faint clicking noise from the rear.

Any ideas?
