On 9 December 2017, from the Ritchie Navigation website, ordered an CS-0025 LED Kit 12V Green NV ($22.22), SH-0176 XSP LED 12V Green GL & NV ($27.66), and a NV-0175 Mounting Gasket ($8.00) with shipping charge of $9.96 to our Los Angeles, California ocean freight consolidator. We received this in Naga City, Cebu on 23 February 2018.
With receipt of the ordered items discovered that CS-0025 LED Kit had a mount bracket and screws, that SH-0176 XSP LED Kit did not - the CS-0025 LED Kit is also cheaper by $5.44. The instructions that came with the LED kit clearly cautioned and recommended the use of a 1 amp protective circuit fuse. As the LED wire leads appeared to be 24 AWG, with a free air ampacity rating of 3.5 amps maximum, this seemed a reasonable fuse value. We would use a 1 amp protective circuit fuse which would correct the previous ill advised connection to the 12 VDC panel circuit breaker rated at 10 amps.
In March 2018, when we returned to Indra at Holiday Oceanview Marina, we removed the compass and its sunshade cover. The wires for the LED light needed to be cut to remove the compass. Could not access the enclosed area in front of the cockpit well where the old wiring was installed, so cut both exposed ends of the wiring and removed all the rest of the old wires.
The LED light assembly had corrosion all over it. Verified the old LED light was inoperative by connecting 12 VDC power to it. It appeared the corrosion on the LED bulb leads might be the root cause as to why it failed.
Before installing the new LED light assembly in the compass sunshade cover, we verified the new replacement LED lights illuminated ok.
New 16/2 AWG duplex sheathed wiring was run from the newly installed 12 VDC panel and negative bus bar at the navigation desk to the compass location in the forward side of the cockpit well. About 15 feet of 16/2 AWG duplex wiring ($6.00) was installed and connected with marine rated splices and connectors ($4.00) with heat shrink coverings. A 1 amp protective AGC glass fuse was installed in the 12 VDC panel for this circuit output. The following diagram depicts the compass wiring circuit.
The new gasket was used when the compass was installed. Retained the old gasket and place it and the SH-0176 XSP LED Kit into the spares kit.
