Soldering close wires

Having issues with the Joystick on the JD3800
I know what the problem is, the wires run down through a center tube which has a pin going through it which has rubbed through said wires.
Easy enough job to replace the wire at the top end of the joystick, but at the bottom end they go onto a circuit board.
Trouble is they are so close together i keep keep bridging to the next wire with solder.
Whats the best plan to get round this
I just have a bog standard soldering iron, do I need something different??

don't solder to the circuit board, solder to a short bit of the existing wire, which will give you more room to play with.
That is unless you have cut them all off at the board in which case refer to previous reply, and upgrade your soldering iron :D

No room to get anything between contacts, they are 3mm apart max
Might have to invest in a fine soldering iron, certainly cheaper than a replacement joystick
Actually surprised at how basic they are inside
Certainly helps when you have the wiring diagram though

I don't see what the issue is, 3mm is plenty of room, put a photo up plz.

You can usually grind soldering iron tips down to a sharper point if needed. Often they just need cleaning on a bit of wet rag/sponge/newspaper because they're gummed up with burnt solder and flux.

As above, tin the soldering iron tip with solder, tin the wires, tin the contact on the circuit board, touch them together and dab the soldering iron on to get the lot to melt together.

Don't forget to put a photo up. Photo of the soldering iron would help too.

Could be on 0.1” or 2.54mm spacing. Standard in circuit boards and would definitely not be called fine pitch.
As above, grind an old tip down if you are having any issues. Or take to your local auto spark or electronics specialist and they will solder it in a few seconds. You definitely should not be shorting out at that spacing, unless you’re using a massive iron for battery terminals etc.
It’s possible you have too much solder on the pins. A solder sucker, or solder braid, or even heat the solder and tap the board of the bench to get rid of some of the old solder, should help.

I have a cheap station like the one in the link. Comes with a 0.8mm tip, and you can buy replacement irons, tips etc.
For a circuit board, and especially soldering to plastic buttons, a temp of less than 400 is ideal.
That particular one is available in various brands.
no need for a metcal or weller for occasional use.
That particular one is out of stock, but they have one with digital readout for a tenner more. Normally I wouldn’t pay extra for that feature for a cheap iron. You may be able to get something similar elsewhere.
Buy yourself a solder sucker and sone insulating tape, contact cleaner and cable ties if you need to make the free delivery minimum

A very fine soldering iron can actually make things worse as it can be difficult to get the heat in without a large tip area.

As above, 2.54mm spacing is standard and should be possible to solder using most standard irons. A roll of solder wick can help if you're applying too much solder at a time.

A man has pleaded guilty at Newtownards Magistrates’ Court to waste offences relating to a bonfire next to the electrical sub-station on the Circular Road in Newtownards, Co. Down.

Gareth Gill (51) of Abbot’s Walk, Newtownards pleaded guilty to two charges under the Waste and Contaminated Land (Northern Ireland) Order 1997, for which he was fined £150 each and ordered to pay a £15 offender’s levy

On June 25, 2018, PSNI officers went to Gill’s yard, where they found a large amount of waste consisting of scrap wood, pallets, carpet and underlay.
