It’s been 2~3 years since I pulled the gauges from the helm dashboard. Kocian Instruments* did a good job making them nearly like new, and they’ve been sitting in a padded box in my basement ever since. With the starboard engine installed and the port engine up next, I need to get the gauges back in the boat and start figuring out the wiring–getting 1960s vintage SAE gauges to work with my Cummins 6CTAs (which I believe use non-SAE senders) will take some work.
- 2016 Update: Dale Kucian sold Kucian Instruments in 2014, and the company under new management is not one I can recommend. The full story from July 2016 is here: Trim Tabs & Gauges
I had Kocian Instruments recalibrate the tachs from 0-5,000rpm to 4,000rpm, since the boat was originally gas powered but now has Cummins 6CTA diesels. By coincidence, the engines came with mechanical tachometer drives, so I decided to keep the tachs old school cable driven.
I now know what every single wire in there does. 🙂
For such a low powered circuit, the compass light wiring sure took a beating. But the rest of the wiring looks surprisingly good, and the copper is bright.
Three of the old Morse control cables had very smooth operation, which was surprising given their age, but one of them was pretty sticky. I could have just replaced the one, but the throttles on the injector pumps of my Cummins 6CTAs and ZF280 gear shift levers are in different locations than the old Super SeaMaster 534ci turbocharged and intercooled gas engines that were in the boat when I got it. So I’ll order a full set of new cables that are the proper length for this application.
