OK. Boat comes in for some booked work and the usual ..."Can you have a look at...."

Customer issue 1 "we have lots of water in the bilges all the time"

cruiser stern with no rear covers, deck channels recently cleared, but drain channels completely blocked. No rope in stern packing, just lots of grease. 

Customer issue 2, "we have no 240v, the inverter cuts out as soon as we turn it on and we think the alternators are faulty" "cant work it out as we have two new(1 week old) batteries"

on opening the domestic battery bank we see.........

.

battery A (OLD) connected to inverter, battery B (old) and C (new) connected to alternator and battery charger, battery D (new) connected to......

 

can anybody see anything wrong with this battery installation? :-)

(hint, the starter battery is on the other side of the engine bay and in good condition)

[churchward]

I may be in the numpty class when it comes to boat electrics but I don't think battery D is connected to anything or at least the positive isn't.

[sharpness]

If nothing else theres some nuts missing on the battery posts

[Rickent]

Matty , have you removed all the nuts from the battery connections or is this how it was.

The last battery is connected to nothing....

[bizzard]

Far battery not linked to the next two.  Near battery not connected. Nuts off.

It must just be me... I can't see anything right with it...

[Rob-M]

It needs an engineer to take a look.

[MtB]

I have to say Matty, I'm not impressed with your installation of those batteries.

Making out it was someone else, honestly!

Probably a pair of small moles. 

[matty40s]

you are all getting there (except mikey )

we did find two more linking cables behind the battery box.

Is battery A the only one connected to the inverter?  Doesn't look like it's connected to anything else , not the charger anyway.

As I predicted, you deny being responsible?!

[churchward]

I am enjoying the picture  in the OP as it makes my battery box installation look quite good!

It's my homemade inductive charging battery module (ICBM) 

It may look like a box with no front on to the uninitiated.

MOAB - mother of all batteries

[mark99]

Series connection, subject to weakest link in chain. Hang on need another coffee can't see well on little screen.

 

Same concl. as Bizzard. Invertor connected to one old shagged battery. No way of charging first in more ways than one.

[Momac]

is this supposed to be all one battery bank ? The first battery appears to be not part of the bank? Would be better if possible, if positive take offs all on batt 1 and negatives earths on batt 4 ...................given missing link  cables also  added.

Also all batteries in bank best being replaced at one time.

[rowland al]

Are the batteries still in the boot of his car?

[Horace42]

Is it a rhetorical question, or are you asking because you need technical help to diagnose the fault and fix it?

[mrsmelly]

And by now the 1 week old batteries will be goosed

Batteries don't have weels, unless you count those golf buggies or milk floats. 

[billh]

I think the carpentry on the battery box could be better, it isn't very neat......
