Finish electrical wiring of jet engine Boat

First step:

Bring in all electrical wires. protecting them appropriate and guide these wires above water-line into new battery compartment.

**Bring all electrical wiring into new Battery compartment and prepare the wires for new terminals**

Second step:

Create a plan for how and were you are going to install the new Busbar’s and circuit breakers and Main Battery switch. The idea is to have a clean cable flow and not a twisted and messy new wiring arrangement. Think also about were you gonna place the batteries and how. The idea is to have all as compact and clean installed as possible. When you got the plan, start the execution. I started in my case with the installation of the new battery tray’s.

The client bought these typ of Battery holders. These typ of Battery tray’s are ok, if the area where you install these types are good protected against water and offer a good ventilation. When considering completely sealed battery types, these tray’s are good, if you have not sealed acid led batteries installed you should not use these type of battery trays. Reasons are Battery leakage can flow out of these type of boxes, better use full battery box in this case.

Third step:

Install the Busbars and Main battery switch as you planned. Then create clean untangled wire flow to contact points and create good waterproofed terminals at each end of the new wires.

I started with the Engine side first and went then on with the main battery switch side. This photo show’s the work in progress.

Adding main battery switch

At this stage I added the new main battery switch and made also the new wires for the new switch

Here you can see work in progress as new battery switch is installed and wired up correctly

Wiring all correctly up

This step is the most sensitive one. You need to create correct wire length’s and correct wrings to each positive and negative pole. At this point you need to be aware to keep all marine safety standards in mind to correctly adapt these codes either AYBC or ICE codes. My wirings are done here in ICE code. Remember all these wirings will be cleaned up in the end with the final touch. Here I started to install the ACR unit with the breakers. On the far left side you see all Blade fuses come together. Later stage I ID tagged these and then cleaned installation. The idea here is to not leave wires and Terminals at the end exposed, use conduits, protect these and keep them above waterline together. Here at the Breakers you can see the factory terminal protection are not good. Later, we covered the exposed terminals.

Last step:

We install the new batteries and cleaned up the whole Battery compartment. The Idea here is to cover any free wire with protective conduit and fix individually these wires to be loose inside the compartment. In our case we use cable ties to make sure that all wires are correctly hold in place against any vibration so to not damage any terminal or wire installed. Finally of course is the testing of your installation. In our case it worked like a charm and our client is happy which makes our company happy.
