Today was a interesting day to be a Perth Mobile Mechanic ! Today in our travels we were called out to replace a faulty car battery but when we got there we found that the car battery was not the problem it was a seized gearbox [due to lack of vehicle car servicing the gearbox had run out off oil ] so we didn’t bother with the battery we just removed the gearbox for service and repairs .
