About 20 min ago I went to start my 2007 Fiat Ducato Camper and quickly found that my son had moved the clutch into first gear while parked. The engine turned as usual and immediately turned off due to the E brake on. This has happened before with no follow on issues. However, on the next attempt the only feedback I got was a single clicking sound and no engine turnover whatsoever. The battery is still fully charged as I am in the middle of a trip. Any feedback or recommendations? Thanks in advance, Trevor.
