How To: C15a Wire-3 restoration

[David Dunlop]

Hi Jordan.

Quite another milestone. Congratulations!

A few posts back you commented about sorting out the Signal Buzzer wiring feed. My suspicion is the feed from the buzzer in the cab to the box is very probably the same on your WIRE-3 as the WIRE-5.

The wire would drop down from the buzzer to the Cab Roof Seam and turn to the rear to follow the seam until it arrives at a hole in the seam that allows it to pass through to the lower wall. Small cable clips hold it in place. On my WIRE-5, these clips were all painted. You should be able to spot the small holes where the clips were secured.

The wire dropped down to the lower wall/floor seam in a fairly straight line and disappears through a hole in the floor, the same size as the one in the Cab Roof Seam. This takes it out of the cab floor close to the Left Frame Rail of the vehicle. It then follows the Left Frame Rail, but I can not remember if that is along the top edge, or close to the top of the outer side. Clip holes should identify the route for you in that area.

At the leading edge of the WIRE-5 box, about 12 to 18 inches in from the left side of the box, another hole in the floor allowed the wire to be fed into a conduit assembly built into the front wall of the Wireless Box, behind the plywood wall. Your WIRE-3 is an open box inside so once the wire arrives in that area in your vehicle, you may have to rely on the small clip holes to guesstimate where it went. If the WIRE-3 box was set up for Wireless Operator seated centre front and a Cypher Clerk to the rear and left of the operator, odds are the buzzer switch was situated to the left side of the WIRE-3 box somewhere easily accessible for either the operator or clerk to use it.

Hope that helps.
