suzook12 Posted October 16, 2020 Share Posted October 16, 2020 First thing I will say here, is if you don't understand electrics, leave it alone and find someone that does, preferably the non stetson wearing, colt 45 carrying type. Usually easy to spot and for the visually impaired, listen out for the jangling of spurs...... Ok, so that out the way...... First tool to mention, the multimeter Multimeter There are loads of these around with many different functions. The main functions you need are AC and DC volts, Resistance and a very useful one, Hz. Aim for around the £30 mark to get a decent meter for DIY level, if you intent to do a lot, names suh as AVO and Fluke....... Clampmeter If you want one of these, check the specs to make sure it does what you want, it could be a very expensive mistake to make. Usually, you would use one to measure amps (they do the V and Ohms as well) as this is what sets them apart from a Multimeter. Crimps Cheap really is not your friend here. The 2 main types for automotive cable are the insulated and non insulated, and they require different crimps. I'll start with non insulated as these are primarily what I use. Pictured above, non insulated type terminals These are the pliers I use for these. You can buy ratchet crimps, but not found the need on this type of terminal Insulated terminals I try and stay away from, but, used with high quality pliers are fine. The ones used in the rail and aero industries are very expensive, like £300+, but that is where you need to be for reliable crimping..... At the very least use GOOD ratchet crimps There are other crimps for battery leads etc, but for this thread, we will stick to basic tools.... Other Tools So what else? Side cutters, wire strippers, insulated screwdrivers..... It really depends how far you want to take your wiring. Hand tools, stay away from the cheapest as stated above, quality really does score in this section Andy135 1 Quote Link to comment Share on other sites More sharing options...
suzook12 Posted October 19, 2020 Author Share Posted October 19, 2020 Some other items to have at hand when tackling a wiring job. Heat Shrink. An absolute must and not that expensive, can be bought ready cut in various sizes or as a length/roll to trim yourself. It comes in various different colours so you could even have a colour code system going on with the heat shrink. Remember to put the heat shrink on first! Fuses Always have plenty of fuses of each and every type you use, keep a good stock on the boat as well Tape Several types to consider. Harness tape, the non sticky stuff tou wrap around a loom or spur from a loom to protect it, held in place with heatshrink. Self amalgamating tape, again to wrap around a harness for protection, bonds itself together to form a more reliable sheath. Insulating, or insulting tape as I often refer to it, ok as a get you home temp fix, but better suited for taping wires together when harness making Gas Soldering Iron These things are brilliant, can be used for shrinking heatshrink to soldering multi wire splices. Just remember to carry a lighter and a gas can Saintly Fish and JDP 2 Quote Link to comment Share on other sites More sharing options...

Andy135 Posted October 21, 2020 Share Posted October 21, 2020 Just to add to @suzook12's post on Electrical tools, you really do get what you pay for. I've had two different crimpers at the cheap end of the spectrum and both times they've started to bend out of shape at the hinge pin when crimping firmly. On one of them the jaws started to open up so that they would never meet properly when closed. Buyer beware! Quote Link to comment Share on other sites More sharing options...

Just remember to carry a lighter and a gas can I had years of messing about trying to use a low cost ellectric soldering tool with poor success. Recently went over to using a little dremel gas soldering tool which has attachments for hot knife rope cutting and a heat shrink attatchmeant and now my connections look very professional. This tool wasn't expensive and seems to run for a good amount of time on the easy to fill gas. There are plenty of UK YouTube videos that convinced me this was the tool to get. When I use heat shrink Ive been putting dialectic grease over my connection, when the heat shrink squeezes down on the wire the grease oozes out ( might not be the way to go but haven't had any problem ).

Another alternative for battery leads is the "hammer on" terminals, although we always did them in the vice for welding cables and they would last the distance SiDfish and captin slows old outlaw 2 Quote Link to comment Share on other sites More sharing options...

suzook12 Posted December 3, 2020 Author Share Posted December 3, 2020 2 hours ago, JonC said: I bought a pair of ratchet crimping pliers last week, not really expensive ones, an about £30 sealey pair. I never knew they were a thing before, always struggled with the crappie single action cheapo things before that have never been any good. Not a bad price range Jon, and you should get a few years service out of them. When I was younger, I bought a cheap pair off the market. They were great for a long while then suddenly stopped crimping tight enough..... Quality of the crimps can play a part too, the RS supplied ones are good, no doubt there are others Quote Link to comment Share on other sites More sharing options...

The aircraft and train boys say no, don't solder, and again, I have worked in the rail industry for quite a few years. The big difference is quality of crimps and pliers. Not just any old crimps off of the market (or ebay these days) but proper quality items from the likes of RS, who supply rail and aircraft industries... Decent pliers fetch around £250 used on the open market, or ermmm get borrowed from the railways..... Quality makes the difference mate. I won't use insulated crimps unless they are quality ones, much preferring non insulated. Excess solder can make the wire brittle and cause it to snap under vibration. To be fair, I've never had that happen on any of the bikes I've wired over the years. What made me switch was the terminals for most multiblocks use latched non insulated terminals. Whatever method you use, make sure you do a pull test on every crimp, you don't want and important wire coming adrift halfway across the Bristol Channel Andy135 and daio web 1 1 Quote Link to comment Share on other sites More sharing options...
