|This blog covers the installation of a stay alive in a Austrains 41 Class|
The ESU say alive is the only commercial product that will fit this engine and requires modification to the hoot to be installed.
Note: ESU stay alive's only work with a ESU decoder.
It is the easiest to do this with the hood removed.
To do this remove the handrails installed into the cab sides with a set of small pliers. It is best to leave the factory foam that supports the handrail for this whole process.
The cab body is secured by six  clips - break the lugs that engage the hood as it is impossible to release all of them at the same time. Using a screwdriver disengage the lugs in the running board by pushing along the board then down - not easy.
With the four  lugs push / pull the cab off - it is tight so care mixed with force is required. Once removed dress the side of the cab where it rubs in the hood to open up the clearance a little - a few wipes with a flat jewellers file will do the job.
Enlarge the slot in the hood to take the stay alive as shown
Note: Remove the capacitor from the board taking note of which side the negative is marked by the stripe on the side of the capacitor, this is the negative side.
Solder a red and black wire to the capacitor to keep track of the positive / negative and reinstall on the board - tape to the engine on the opposite side to the decoder
Test and reassemble.
