Since one blew up in a friends face I've become a tad nervous of batteries. I have 4 knackered ones to remove and 2 to replace them with. There seems like a lot of stuff attached.  In general so long as everything attached to a +ve ends up on a +ve and -ve on -ve that should be ok? There are lots of sense wires, I don't know what for exactly, they're hard to follow, but there's a volt meter, the mains charger, a multi battery isolator (right in the picture) that connects to a relay, maybe the central heating. I'm not entirely convinced that the isolator switch will isolate everything but I'm a bit of a cynic. Anything I should watch out for? I thought I'd start by removing the extra links I won't need and attching sense wires from those batteries to the terminals that will have batteries attached when I'm done. I have a couple of rubber gloves to shove over worrying flapping bits as I go. Ooer. |

The multi battery isolator seems to be for the engine and bow thruster batteries so no need to worry about that though it's connected to an alternator too which seems odd, I'd have thought isolating both from the alternator would damage it? Anyhow, that's for another day.

on the plus side (no pun) at least they're accessible... mine are a right bar steward to get to - as I found out when I'd just had my first carpal tunnel done.

Wear safety goggles if you are worried about batteries exploding. Also rubber gloves to avoid getting electrocuted.

Best to use insulating tape to cover your spanners completely so you don't create a short by accidentally touching the hull.
Also remove or tape up rings and remove wrist watches, dangling medallions etc.

I manned up and got on with it in the end. As noted they are easily accessible. Just a matter of one thing carefully after another. No sparks or dramas.
I was hoping that among other things it would cure my webasto failing to light problem. No such luck.

I'm impressed you did it yourself.
Don't get giddy.
Others will tell you I am easily impressed by people who have the abilities and commitment to do work themselves.
But well done anyway.

Rog Generally, lately at least I've been a lazy git as andyberg will confirm. But  in the last 5-6 weeks I've moved the water tank from one side of back bedroom to front central, moved the water pump, moved a radiator, rebuilt the radiator cabinet, moved the dinette table c/w section of reinforced floor to lounge, made the dinette into a bedroom with storage, made a big seat/guest bed with storage under, stripped the rear bedroom, repanelled walls and parts of ceiling, used all the bits of wardrobe to do the above, made a door and bulkhead, made a high level cupboard, made a desk, made 2 single beds from scratch, made a suite of 4 drawers under from scratch, boxed in all the pipework, moved light switches and sockets, laid new carpet, remodelled the side hatch access steps and made a kindling store under one step, all in the style of the original oak fit out, well oak trim and oak faced mdf and plywood... There's more I'm sure, I just pretend to be a bit hopeless.  I am cautious of rows of powerful batteries though, I'd put it off for a month. |

...and moved a suite of high level cupboards from bedroom to kitchen, I chucked the original kitchen ones, too big and ugly and in your face. It's been fun to try and reuse every scrap of the original bedroom full of cupboards.

You are of course correct. But you need the right tools, and parts. Then you need the confidence. Got me there Rog |

Got me there Rog I had a business designing mobile phone transmission sites after teaching myself autocad and getting a lucky break. Too much sitting at a computer made me a bit ill so I rebuilt an engine (didn't have a clue what was inside an engine when I started), taught myself to mig weld, restored a vw camper, then other people's for a decade, built more engines, learned to spray paint by pestering someone, then stopped everything when my marriage broke up a few years ago. It's narrowboats now lol, In 15 months I've pretty well done everything spread over two boats except for engines but if it broke I wouldn't even care, I'd take it to bits, see what was wrong and mend it. |
