In the process of rebuilding Windsong I am uncertain if I should ditch some old equipment or try to keep it going. At this time none of these pieces of equipment are functional, and I had not bothered troubleshooting since I figured I'd try to salvage what value I could out of them by selling and upgrading. However, as the list of things I need to buy grows, I am further seeking to save a buck. Please tell me if I should keep it or ditch it.
1. 1993 Seafrost SA-III (134A) Series engine driven & 120 volt refrigeration & freezer system. I would like a DC system, but have given the current one some thought. It is already set up, though I would like to give the boxes more insulation before cruising. I plan on cruising in the tropics, and I know that matters when choosing a fridge system. I am curious if this old system is worth keeping though.
I don't really like the idea of an engine driven system, I'd rather keep my batteries topped with solar and an good alternator and have a constant cycle DC system. Is that a good idea or should I seek to get this one working? Would this old system have any value to sell? Any particular units I should look at to buy? Since the system uses chill-plates, and they are already installed, would it be worth ditching the engine driven compressor and just buy a DC run unit to use with the existing set-up? If I have a DC unit, I question keeping the AC unit since if I were to be tied to shore-power I would be charging my batteries regardless.
2. 1983 Alpha 4404 Autopilot. I would like a windvane for my self-steering, but want some sort of back-up and for motoring. I figure I would get a wheel pilot, but this old beast is attached to the boat. There is a mechanical control arm, a cockpit control unit, and a compass unit. I wouldn't know where to begin to start troubleshooting this, but would be willing to give it a shot. If just one of the three parts needed replacing, would these old things be worth trying to get going?
Any opinions from my wise readers would be appreciated!
