Today I stopped at BCF just out of Wagga Wagga and when I turned the key... nothing.
Because it's an old van I decided to join the NRMA and today I took advantage of that with their roadside assist service.
In these Hiace vans the engine is under the passenger seat. The technician seemed ready for a battery replacement but my volt meter showed me that the battery was fine. The starter motor is underneath and a rap with a hammer and it worked! The guy explained that this is a common short term fix but in the end the problem will re-occur.
I've had the starter motor replaced for $380 (with member discount) and I'm pretty happy with that. They fixed it same day but I'm staying over in a motel. Hitting the road again in the morning.
I feel very fortunate to have broken down in a town rather than up a muddy, rarely used track, with no mobile reception. A close call.
