    420 DA Thread

    My apologies if this post is in the wrong section, I did post in General too.. with no response. I realise this is a difficult question to answer specifically, as there are many parameters involved... but, I have a 1990 sundancer 420da with 2x caterpillar 3208T engines. The boat will reach 21-22...

    1990 Sundancer 420DA fuel consumption

    I realise this is a difficult question to answer specifically, as there are many parameters involved... but, I have a 1990 sundancer 420da with 2x caterpillar 3208T engines. The boat will reach 21-22 knots at approximately 2,300-2,400 revs. Can anyone give me an idea of the fuel consumption at...

    420 DA Thread

    Thanks for the responses.. yes an older 420 DA. Yup as slow speed it just turns, and turns more than the rudders can counteract. Both engines are out right now, the boatyard mechanic and I are rebuilding them right now, the blocks have just returned from the engineering shop with liners in them...

    420 DA Thread

    Hi folks, has anyone ever tried running their 420 DA on one engine? I had a problem with the starter on the port engine, thought I would have a go at getting it back to the marina from where I was moored… set off at crawling speed and after going round and round the mooring gave up, tied up...

    1990 420da alternator wiring…

    Hi all, update…… So, the mechanic replaced the two blown alternators and my next task was to fill-up so we can take the boat for a test run (check for oil/ water leaks) and to see if the prop-shafts need alignment. Started up the boat, all ok… left engines running for 10 mins and drove it round...

    1990 420da alternator wiring…

    Hi Hughespat57, many thanks for the latest update.. apologies for the late reply. I have been away sailing for the last week (yes, I venture on the dark side of boating too). Well in my absence, the mechanic has called in a marine electrician to which they have identified that he has blown-up...

    1990 420da alternator wiring…

    Hmmm.. starting to struggle with this now. There appears to be two harnesses. One goes back into the depths of the boat.. I’m assuming the dash at the helm via a multi-way connector and the other harness really doesn’t have too may wires.. they seem to be initial power related rather than gauges...

    1990 420da alternator wiring…

    Hi Hughespat57, Some feedback for you… Ok, I’ve been to the boat today and put the multimeter on the connections. They are both hot (+12v) all the time. It doesn’t matter if the helm dash engine switch is off or even if the main breaker panel is off, or both of them together.. they are...

    1990 420da alternator wiring…

    Many thanks for the update… I’ll be at the Marina tomorrow and check this out (and report back!). Thanks for the English comment.. it’s actually my third language but I lived in Boston and Philadelphia and London for several years.. so I’m quite used to using it. Thank you again for the assistance!

    1990 420da alternator wiring…

    That’s fantastic…. Ok.. so to make sure I get this right and not blow the alternator charging capability… 1) Thick red wire coming from the battery isolator.. it definitely is an isolator (because it says so on the box), then that wire goes to B+ On the alternator 2) Thick black wire coming from...

    1990 420da alternator wiring…

    Many thanks for the response Hughespat57.. I also managed to find that which is really helpful.. if only I understood it! I presume that the B- would be both the black wire and the yellow/green one? The Exc connection? I’m assuming must be the excite one but which wire goes to it etc. Sorry...

    1990 420da alternator wiring…

    Hi folks, Can anyone help please….. I have a 1990 420da with 3208ta 375hp engines. The local caterpillar mechanic here (in Cyprus) has had both engines out along with the gearboxes and overhauled both sets of units. A great job and good work! However… his helper that assisted in disconnecting...

    Sundancer entertainment centre

    Just thought I would update this thread in case anyone else had a similar problem... So I found the rougue 'device'. It was a kinda home-made audio filter. It was located behind the entertainment centre cutout, almost behind the right hand sliding cupboard, so you couldn't see it! I had to take...
