Modifications & Equipment / Where can I connect my new freezer?

« Last post by Ailatan on March 31 2024, 20:55 »

I was thinking of connecting the new portable freezer to the positive and negative poles of the Danfoss compressor of the fixed fridge, please look at the picture.

Is it a good or a bad option, any suggestions?

Thx

Well done, I had similar problems but I only needed to remove the top part.
After cleaning everything with a rust remover I found out that everything was in perfect condition so I put them back in place with new sealant so no leaks since then.
There is a post in this forum somewhere with pictures similar to yours.
In any case I understand that if you didn't feel 100% safe with the situation of the tie rods you did well cleaning and ordering new parts

Nice work. Can you show the ball head of the tie rod as well? That's likely the critical part.

On ours, one of the through-deck bolts had a crack in the head, so I replaced them all. The rest was fine, although ours hadn't been leaking for as long as this one. Polish it all up and check for cracks (can use dye if you want to be fancy). Unlikely there'll be any problems with the lower bracket, it's massive.

Update #3

Today I got the whole chainplate assembly off the boat. I had to remove the galley sink to get proper torque applying access to the 45 mm large nut holding the tie-rod to the bulkhead bracket. It took some large wrenches and a plenty supply of penetrating oil to get the last nut off. Now the galley is a mess, however on the upside the hardware does not look even half as bad as it did when it was still mounted to the boat.

To be honest, the parts look OK to me. However there is still two dark corners to explore - namely the stainless tie rod itself is a "free floating" piece. On the deck side it is sitting in a ball joint and on the bulkhead side it is somehow stopped in the cylinder from which the massive 45 mm threaded rod sticks out of. I'm going to look at the floating points and see if there is anything up there.

I'm having second thoughts on having anything replaced in this assembly. However, as said, I'll open up the tie rod joints, clean all the parts up, inspect them and see if I can find anything. I'll maybe swap out the tie rod, as it is the thinnest part in the whole assembly. Everything else is massive compared to it.

Again, any ideas-suggestions are welcome.

If the original alternator was isolated, that's usually to minimise saildrive corrosion (on later engines the saildrive itself was electrically isolated from the engine).  Fitting an unisolated alternator may give you corrosion issues.

Perhaps ask a marine electrician to take a look and advise you?

Please help me with wiring the alternator.  I changed the alternator, until now I had the standard alternator that comes with the VP2030, the new alternator is 100 ah.  I made the mistake of not taking a picture of how the old alternator was connected, I think it was isolated so it needed a minus wire.  As far as I can see, the new alternator minus pole is connected via the housing to the engine. Service technician who installed the motor is not an electrical specialist and obviously connected it incorrectly.  Because the batteries don't charge and the rev counter doesn't work.  I see that the two wires are not connected, but I don't know where to connect them.

Update #2

I got the chainplate off yesterday - in fact it was not under much pressure. I held the deck bolts with a hex wrench and undid the nuts of the backing plate to which the tie rod connects. I was fully expecting the bottom plate to "snap down" when loosened, however this did not happen. The tie-rod is still stuck to the hull. It is a rather elaborate system. Once I get it all off I'll upload a picture. I need to go buy a 45 mm wrench..
