Hall Sensor Protection Bracket

The SDS Hall sensor sits in behind the flywheel on the right hand side of the engine, attached to a bracket bolted to the forward 2 case bolts. 

This location is very close to the alternator belt - there is a concern that should the alternator belt break, flail around and damage the wires to the Hall sensor, then the engine will have no idea of the position of the crank, and therfore no idea when to fire the plugs, or inject the fuel. 

It's kinda important! 

As such, i decided to make up a little bracket to cover the wiring at the sensor, and will route the wires in a piece of fuel tubing which will eventually be bent and penetrate the forward baffle, to run the wires for the hall sensors along the top of the engine to the ECU. 

This is what the hall sensors look like - they are potted in epoxy into a nice billet case:

The case gets mounted to this nice billet bracket, which is bolted to the forward 2 case bolts:

Here are some examples of how other people have protected these critical sensors:

I started by bengine up some thick sheet, then trimming it to fit.

I used some scrap fuel tube to protect the wires out the back of the sensor.

The tube is help on one end by an ADEL clamp, and at the other will be bent to go through the baffles and will be held using a silicone grommet. 

It was finally primed and painted in a color to match the baffles:

I will install onto the engine during the engine build (hopefully soon), and bend the pipe and fit through the baffles.
