`So you don't think much of my suggestion to read the manual then?
Manuals usually have a "Things to check when it doesn't work" section.
I haven’t got a manual.
I’ve got new capacitors so……do they need to be “flashed” before installing?

Without a multimeter and diagnosing your fault you're just peeing in the wind.
Could be anything from a bad connection to the socket, loose wiring, circuit breaker, capacitor, loss of residual magnetism. ( Bad capacitors will usually be " blown" ie bulging out of the outer case. )
I’ll check the capacitors, the socket and wiring. Shouldn’t be loss of residual magnetism because it’s been in regular use.

Suddenly there is no power coming from my Mastervolt Whisper 6000. Starts OK. Any idea as to likely cause?

Well I’ve learned a lot today. I didn’t know the cable was so crucial. Can someone give me an idea of where I can get a high quality cable and adapters. I’ll get a Fringe LED signal finder meter as per advice from OldGoat. deleyCON seems to be a decent brand, (gold plated plugs etc)
you never stop learning?

You can actually get a special 'piece' for passing thru windows, down mushrooms etc, it is a short length of thin flat cable with a connector on each end. You can bend it thru 180 degrees and it still works
'ere U go.

But to answer the original question: yes, it could be the cable. The signals involved are tiny, so it's essential that the cable is the right quality satellite cable (not just any old coax) and joints are very well made and kept to a minimum. Ensure its kept dry and well sealed where exposed and don't exceed the recommended "bend radius" of the cable where you go round corners.
Straightened the cable where it goes through a Mushroom, result ……picture on the TV! yippee! ?
thanks to all for advice.

Try the sat finder on the cable at the TV end, that should let you see if it is a cable issue, and as said are you certain you at on the correct satellite.
That’s a good idea?

Could be the recommended bend radius is the problem. I didn’t know there was one!

I’m getting a signal reading from the meter on the dish (which is pointing in the right direction for Astra 2) but my HUMAX receiver says no signal. I know the LNB and the Humax are both OK so could the problem be the cable?

A bit of bulging is normal, as long as its not too bad.
Top up the water, do a good charge then an equalisation for a few hours and see how things go. Trojans do recover quite well.
Its also quite possible that only a single cell has failed but even if that is the case at 5 years it would probably make sense to replace the whole lot.
We are full time off grid liveaboards and our Trojans are just over 5 years, still ok but not sure we will get another winter out of them.

They are only slightly bulged. They seem to be coming back to life, so should get me through this summer.

Well running the engine/alternator has certainly made a big difference?

What are the times and values the controller is set to? If by some chance its for sealed batteries or AGMs the voltages are likely to be too low for open cell LAs and it may not do an equalisation.
They're set for Flooded Lead Acid. Strangely enough the Trojans seem to be coming back to life after a few runs out in the boat, with the Leece Neville banging in over 100amps?
-
I understood that the Episolar controller was supposed to automaticallyngo into equalisation once a month.
Maybe I would have been better off fully charging then disconnecting thd batteries.
They don't get warm btw.

Look at the case ends. If they bow out the battery is badly sulphated.
They are bowed. But how could that happen with solar/MPPT over winter?
-

The charger had probably dropped into float voltage because the batteries are so sulphated, the remaining capacity was charging up (voltage rising) so fast. This indicants that you have probably been rarely fully charging them and have no facility to do an equalisation charge. If your charge has an equalisation setting use it and it may buy you some time.
How do you decide when to stop charging and what battery monitoring equipment do you have/use.
They've been on constant solar power over winter via Episolar MPPT controller with no power being used.

My 5 year old Trojans look like they're on their last legs. 11.9volts this morning! I fired up the genny and the battery charger "Charge failure" light lit up and it took 4 minutes before it kicked in. It went into bulk charge (surprise, surprise!) at 80amps, but within 30 minutes, had dropped down to 12.7amps. But when I'm running the engine, the Leece Neville alternator is constantly banging in over 100amps.
I thought the batteries determined how much charge they want, so how come the battery charger is dropping down so quickly?
-
Sorted?. Thanks everyone for the advice.

The capacitors are classed as a service item normally being replaced every 2 to 3 years they are of the voltage control system..
No idea but it sounds like it's worth replacing them to see what happens

Not your bog-standard type. What will the generator run, without problems?
Kettle & halogen hob

When were the capacitors last checked?
In the genny? 5 years ago.

First component in a microwave is a powerful transformer with a heavy inrush current. I think this is a power problem rather than waveform. What WILL the Genny run?
Halogen hob no problem.
I have noticed that the genny seldom goes above 25% output. If I switch another appliance on, rather than go up to 50%, the other appliances “slow down”.

Sounds to me like the Genny output is low (thank you captain obvious). Don't have it set for 110V by any chance?
No definitely 230v. I know washing machinesvcan be awkward, but...a toaster?!
-
When i run my genny to boil a kettle or run my toaster, it takes a long time and my microwave although the turntable goes round, doesn't heat anything. But if i run the microwave on the batteries via inverter no problem?

You dont get diesel bug without water.
The bug lives in the interface between the diesel and the water.
Good point

New capacitors fitted and Genny fully functional. ⚡️⚡️Yippee!👍
