Click the electrical schematic for a larger veiw.  It will exceed the size of your browser window but you see all the details.  This schematic shows the hookup for a Kohler 16HP engine.  All other engine hookups will be similar.  Just connect your wiring to the corresponding equipment.

You are welcome to download this image and use it as a guide for your craft.  YOU are the one that is ultimately responsible for the proper connection of all the equipment on your craft.

Remember to use this diagram as a GUIDE only!

What did I do today?

Hours

12-13-99

I started to create the electrical schematic for the craft.  I will log this work in my construction time totals since this is something I had to the design and build since it was not provided in the plans.

Completed the wiring schematic for the craft.  You can bet there will still be more modifications to it as I go along!

After I did all the priming & painting today I decided to install the electrical conduit under the port side deck.  This will provide a sealed passage from behind the dash into the port aft flotation compartment to protect the wiring harness from weather and also chafe from gear stowed under the side decks.

I added a mounting base for the electrical terminal strip that will be in the port aft floatation compartment.

I just had to go out and do something so I installed the steering wear plate on the steering crossbar.  Then I ran the wires between the terminal block under the dash to the terminal block in the port aft flotation compartment.

I installed the conduit between the engine deck and the port floatation compartment.  I removed the engine cooling shrouds and stripped all the original wiring harness.  I laid in all of the small gauge wiring and attached it to the terminal strip in the port flotation compartment.  Then wire pigtails were attached to the terminal block under the dash.  I also tried to replumb the oil pressure sending unit.  The new sender for the gauge is bigger than the original unit for the low pressure light.  One of the nipples is a little short and will be replaced with a longer one after the next visit to the hardware store.  The engine cooling shrouds were then reinstalled.

I cut and mounted the keyed ignition switch and 4 toggle switches into the dash panel.  The instruments and switches were wired to the terminal strip, ground buss and the fuse block.  Initial electrical tests may be on 05-26-00.

05-24-00

I installed electrical conduit from the engine deck to the battery compartment and from the dash to the battery compartment.  I ran the wiring from the dash to the battery compartment for the main power feed, the fuel pump control and the fuel sending unit.  I then completed the wiring behind the dash panel.

05-25-00

I finished installing the battery cable conduit from the battery compartment to the engine.  I found a couple more wire to connect behind the dash.  The oil pressure and oil temperature sensors were wired in.  Then the wires were run to the auxilliary electric fuel pump and the fuel tank level sensor.

I installed the battery cables from the battery to the engine and connected the main power feeds from the dash to the battery.  I cleaned up some of the wiring harnesses and got them well secured out of the way.  I did a test run of the engine again today only this time it was with the new wiring system.  The engine started and ran great, the emergency shutdown switch functioned very well (I found this out once I realized the engine wouldn't start because it was set to the kill position, one of the hazards of new installations and no switch labels!).  None of my instruments worked except for the Ammeter.  I discovered that I had missed connecting a ground wire to each of them.

Wired the bow light and installed the ground wire for the instruments.

05-28-00

The anchor light and the yellow flashing strobe light were installed and the wiring was installed.  The wiring behind the dash was tied up and secured.

 Well this about completes almost everything.  I think its time to go and see if we can take our maiden voyage!
