Seen here is the main electrical control box in the cab of bus No. 350. A recent fault with the starter motor lead to an investigation to check the electrical integrity of the starter circuit. On dismantling the control box, it was discovered that a small piece of former fuse material had possibly come into contact with two separate terminals. This fuse material may have dropped down many years ago and lain undisturbed until now. It had the potential to do an awful amount of damage but fortunately this threat has been removed.
The errant fuse material; about the size of a fingernail.
