FH - wiring harness

 I'm not going to blog the complete build of the wiring harness, because I've done that a few times already for the Square and the W/NG. What I will do is show you a few details of the harness as it comes together.

This picture shows the arrangement around the back of the toolbox. From the main harness there are branches going to the horn, to the regulator, to the battery and to the stop switch.

I will probably add a series of bullet connectors to allow me to separate the main harness from the harness going to the rear mudguard.

This next picture shows the main earth cable to the rear which splits into three near the indicators. There is a soldered splice under that heat shrink.

This picture shows the harness going to the rear of the bike with that soldered splice and the wires to the indicators and the rear lamp all covered with PVC sleeving, with a heat shrink section around the joint.

The bike is running an original Lucas 529 which needed to be rewired. I've replaced the cabling and used some heat shrink to provide some wear resistance where the wires go through the rear of the lamp. The connections to the bulb are blobs of solder flattened on the linisher.

Here's the engine earth. This is taken back to the main frame earth which is the upper of the two oil tank bolts. I need to clean the Wellseal off!

For the record this is how I have terminated the magneto kill switch. There is a length of cable, covered in heat shrink, passing through a small length of fuel line which sits neatly inside the thimble nut on the end of the magneto. This end is now weatherproof.

The other end of the magneto cutout cable is soldered into a push button at the handlebar. The joint is hidden by a piece of PVC sleeving pushed over the button - I didn't have any suitable heat shrink to bridge these two sizes.
