i just changed my battery over and realised that the terminal is cracked and therefore loose.i wondered if anyone had renewed a terminal before and if so how do you connect it to the original wiring

thanks

Assuming that you mean the cast-lead one; either fit a complete new lead; [pricey] or get a screw-terminal [or solder-on] one from an accessory shop.

The easiest thing to do is to get a screw terminal as a replacement. Basicaly you get your broken terminal off the lead, trim the insulation back by about an inch, slide the new terminal on the wire and then tighten up the two screws that grip the wire into the new terminal. Then refit the termainl onto the battery and you are all done. You can use a solder on type terminal which is basically the same, apart from you need to solder the lead in to the new terminal, rather than tighten any retaining screws.

If you are going to solder it think industrial size soldering kit!

Copper is a very good conductor of heat as well as electricity. Even a 100w iron was incapable of soldering jump leads to clips , I would guess a gas heated solder pot was required to tin the flexible multi strand cable first.

Blowlamp is what is needed tho' at work we had a 500w. iron;used it mainly for sheet metal work.

ive decided to replace the battery terminals becasue the others are loose and cracked and bought the replacements todays. instead of soldering them im going to use the screw thread terminal. before i start i just wanted to check the wiring with anyone who knows about electrics. there is 3 wires for the positive (2 to the fuse box and 1 main or large wire)
if i strip these back do the 2 from the fuse box go together into 1 screw and the main wire into the other?

the main wire also looks very thick i havent striped the insulation back yet but is this one thick wire or lots of thin bunched together?

cheers

Yes you are on the right track. The big wire is a thick multi core cable that feeds the starter motor. The trick with the screw type terminals is to ensure they are fairly full so you gat the greatest contact when done up. Remember to note any radio codes etc. Regards Peter

thanks peter...when i put the wires in at each end do i need to be careful not to touch the wires togther and leave a gap before clamping them down i dont want to cause any damage and will the multicore cable to the starter be a good fit?

is there anything else as regards to earths or any wiring thats worth taking time to clean up spray wd-40 etc

cheers

Just leave the negative earth connectio off and tied back until everything is done and secure and then relase the earth cable and make a clean connection. Be Careful. Regards Peter

sorry if ive put this thread up before but im still no furthur. I need to replace the positive battery terminal becasue it is cracked and loose. the new terminals i have are the screw type where you put the wire through and clamp it down. the problem being that the positive wire from from the starter and alternator are to thick for the new terminal. is there any other way (apart from soldering) to attach terminals securly.

cheers

An auto-electrician might be the best and most reliable way forward. The connection has got to be really good for everything to work well

Those replacement screw-terminals come in a huge range of sizes to accomodate cables up to an inch thick. Take it back to your supplier and swap it for a bigger cable size.

If they haven't got one; look-up your nearest LSUK or auto-electric suppliers on Yell.com
