Thanks again for the replies. It would appear that installing gauges on all seven condersers is fraught with difficulty. Here is a valve... similar on all seven condensers . This unit is low on gas. I guess thats why there is frost on valve. Is this what is referred to as a schrader valve...

OK. Thank you for the replies. In that case could I simply purchase a three hose aircon technician's gauge set and do this test myself every so often? What parts would I need to do this and what is the proceedure? I am trying to track leaks and not be so beholden to the marine aircon guys who...

Is it possible to install gauges on the aircon units to monitor gas levels? Does anyone have some photos of this? Could you point me towards suitable products on ebay or the web please.

Re: Now 48 Volt Lithium House Bank Upgrade- Silent Ship I thought I would provide an update to this project which has been operating the past year. It has all worked better that we could have expected. There have been no issues with the Victron equipment, other than understanding how it all...

Enjoy this 1991 72MY boat tour.... Its spectacular. https://youtu.be/Zo5ZGnpUvc4

Curious: What is the cranking amps (or watts) required for a 12V71 32 volt starter motor please? At the moment we have 4 x 180ah deep cycle golf cart batteries in series to start each motor. But they do not give CCA.

Been following this thread closely..... The 120v compressor has seized on the original twin room R22 7000 BTU Cruisair. R22 is now banned in Australia and cannot be sold. R22 systems are being refilled with "compatible" R438A." Two of the aircons on my boat are already filled with R438A. I...

A year into this project now and finally the solar panels are now mounted to the flybridge roof. The panel edges have been painted white. The roof is made of flexible aluminium sheeting over ribs, but the sheeting bends under a persons weight. In the end we used PVC solar panel mounts and...

The flybridge roof is finally painted with an epoxy primer and two coats of two pack white paint. We tested the new Furuno Wifi radar in situ and its fantastic on the iPad. It will do what we need. And I like not having the huge old radar display sitting on the wheelhouse dash. However the...

The 36 year old 32 volt working radar has been removed from our boat. Before it all goes to recycling I wanted to check if anyone wanted the circuit boards from the display or radar array. There must be some units still out there. There is an extra board in the display for an external radar...

So here is where we have got to....... Power from the inverter and auto transformer enters the Port engine room's blue door circuit breaker enclosure from conduit below. This enclosure has a 3 pole 20 amp MCB (Master Circuit Breaker) for the L1-N-L2 output. Inverter power to the Starboard...

I am getting ahead of myself. This thread only relates to the movement of the bolt on the throttle linkage as per the original photo. The mechanic said that if it was in the original position the motor would open throttle IF the cable broke. So he moved it to a new position. All I wish to...

A passing Detroit mechanic quickly gave the engines a once over and said the booster spring for throttle /governor was incorrectly positioned. This would have been set in 2005 when the boat lived in the USA. He explained that if the cable failed then the engine would immediately go into full...

The big lithium battery is charged only by the Victron inverter/charger and solar. Its not connected to the alternators in any way. The Victron gear has its own safety settings for overcharge and discharge. The 250amp internal Daly BMS has its own Bluetooth enabled settings. The Victron...

So back to the original solar inverter project that stalled due to our lockdowns last year. We have started to prepare the roof for the new solar farm. We have killed all the lichen over a six month period and cleaned and sanded the flybridge roof. Any bare aluminium will now be touched up...

So Oscar's flags had us back down to the boat this morning staring at the AC panel wiring and CBs, wondering what is the path of action? The voltage step down boxes described in my previous post were a thought bubble, but would have worked. So how do we do all this without modifying the AC...

I am wondering if anyone has replaced only the blower motor before, rather than replaced the entire motor & housing? The motor is a Dayton 3M726A 240v which I see are available. There seem to be only two long bolts. Does it just screw in or are their nuts involved? The last time I replaced a...

Another day with my head in a hole..... this time removing a burnt out air con blower in the stateroom. I don't understand why Hatteras installed two air handlers when one larger one would have been just fine. ++++ So the project investigation continues. - The 240v aircons will all work...

So the decision is made to make the existing aircons operate off DC, genset and shore power. No turning back. This is a DC project and thread. I guess it comes down to how you use your boat. We are on a swing mooring with no shore power. Sometimes we are on board for only a few hours on...

Hello All, This is a new thread about achieving the goals of DC power for existing aircons for our Antipodean Big Loop trip. Its not about the pros and cons of lithium batteries. ++ Following on from the 2021 lithium battery installation we'll now power the OSR, galley and twin cabin air...
