griffipaul Posted October 27, 2019 Report Posted October 27, 2019 Need new battery for mk2 vitesse. Current connectors are the 'pot type ' with self tapper in top of terminal . cannot find a battery with this type... seem to be correct posts but not drilled. do you need to do drill yourself or Is it better to change over to clamp connectors . If so I'll replace the whole leads also.
Colin Lindsay Posted October 27, 2019 Report Posted October 27, 2019 It's usually only soft lead so use a very thin drill, a hand-held Dremel-type drill will do it. Just make sure it doesn't damage the terminal, and that the self-tapper is also of a size that will fit but not distort or split the terminal. Other than that, it's a simple job.
JohnD Posted October 27, 2019 Report Posted October 27, 2019 Self tappers self defeating, unless you never need do it again. By design they tap out whatever they are screwed into, so after a while the post is ruined. Invest in terminals that bolt tight around the post. John
Pete Lewis Posted October 27, 2019 Report Posted October 27, 2019 yes go for some new shiny clamps the old cup type get a coating inside and make poor area of contact , its always a good idea to clean up and scour the posts to remove the hard lacquer stuff that develops and get to nice lead coat all with some grease when assembled not on the connections just the outsides any corrosion growing is easy removed with a splash of boiling water ( think H and S ) pete
griffipaul Posted October 27, 2019 Author Report Posted October 27, 2019 New clamps and leads it is then. New hi torque starter motor took out the old one , starter engaged did not turn and then retracted , all electrics dead , battery reads 12 v unloaded but 0 v with just ign on . Tried new motor with jump leads on tr6 battery with fingers crossed and works ok. Many thanks o wise ones..
dougbgt6 Posted October 27, 2019 Report Posted October 27, 2019 I used self tappers for years, disconnected, reconnected, many times, never had a problem. If they get a bit loose, get a bigger self tapper. However, I have recently gone for clamps because, as Pete says, they're shiny It might be me but the posts on my battery appear tapered, certainly the old caps could be pressed down until they wouldn't turn, no screw connected. I took the car for a drive and later discovered the clamps loose, a bump in the road and they'd slid up the taper. You have to do them up really tight to stop this happening, which of course distorts the post probably more than the self tapper. But they're bling so I'm not bothered. Doug
Pete Lewis Posted October 27, 2019 Report Posted October 27, 2019 yes they are supposed to be a taper post on our batteries if it pops off you need more marmite !!!! unless you convert to something more modern and blingy

Pete Lewis Posted October 27, 2019 Report Posted October 27, 2019 doug guess thats possible , old habits and all that, you need to keep the air and moisture away but adding grease to the parts you want to make good contact it is not a good idea pete
Guest Posted October 27, 2019 Report Posted October 27, 2019 I always thought the advised medium, to place on battery terminals, to keep out moisture is Vaseline and certainly not grease. Regards. Richard.

Theres some talk on here https://community.screwfix.com/threads/why-grease-battery-terminals.27630/ I suggested grease as only Doug has any vaseline !!!! Well most have grease and better than the corrosion Sealed batteries are inherantly less of a problem ....times change things for the better Pete

Doug I've rarely read a post so lacking in self awareness! First you deny any problem with self tapper terminals, then admit to having to use a bigger screw. Exactly the problem I warned against. Then you admitted how loose they taper post terminals can be, if the screw is loose. Really, I couldn't have used better examples of why they are so poor as battery terminals, but then I've never used the damn things. Thank you, Doug, for providing all.the evidence to disprove your own.point. John 1 1 3
dougbgt6 Posted October 27, 2019 Report Posted October 27, 2019 Thanks for that John. You warned against it, well death doom and Armageddon! My point is, it's TRIVIAL. The self taper distorts the post, the clamp distorts the post, it doesn't MATTER. Lets get on with some serious stuff and stop being smug, rude and offensive? Doug 5 1
Clive Posted October 27, 2019 Report Posted October 27, 2019 If it any comfort, I can happily vouch that the only real downside of the cap type terminals is the fact the battery terminals are a sod to drill. The lead grabs a small bit which breaks. I have had several Triumphs with the caps, and apart from the issues drilling (and the odd broken drill) I was perfectly happy with them. Just my experience.... 3

I've read both of the threads a number of times. Have to say, Doug did not say he had to use bigger screws but advised that it may be necessary - obviously in some cases this may apply to other owners. This Forum is about assisting / advising others who are seeking answers to their vehicle issues. It is NOT a platform to demean people publicly nor to score points if that persons observations do not fit in. May I suggest that a more helpful constructive approach is adopted in the future which will benefit all. Regards. Richard.
Pete Lewis Posted October 28, 2019 Report Posted October 28, 2019 Yes back to the plot the taper cap and screw was used extensively for more years than I care to quote , common on cars through The 50 60s and 70s with all sorts of screw and many caked in green grotty, some refitted with a good wack to lock the taper on destined to crack the case sealing and use any screw that gripped, more corrosion then followed, The sealed batteries have made great improvements in corrosion whatever the terminal And on the screw front ive repaired loose terminals with acme threaded tappers nice hex head easy to remove, and no terminal damage Yes drilling lead is silly stuff. Slow and steady and bigger doesnt clog and jam the bit as well. Pete

Pete Never had any problems with the original terminals, cap fitting and self-tapper, but then my battery goes in and stays there for a year or two. I don't remove it so much that I'd ruin the terminal with repeated refitting. The screw is just a light fit to stop it jumping off; not to bolt it down tightly - plus on the GT6 it's only on the short earth strap; the positive terminal is a clamp.
ahebron Posted October 30, 2019 Report Posted October 30, 2019 I coat the terminal with vaseline then warm it with a hairdryer. Adrian

Pete Lewis Posted October 30, 2019 Report Posted October 30, 2019 hot vaseline.....HMmmm sounds like Dougs been involved ?? yes exploding batteries ...managed that at school with the old glass accumalators had a load in a row and we were welding name tags as a dead short and KaBoom it stuck the terminals into the ceiling tiles only the metal carry strap saves us from terminal and glass ingress. i guess we learn as we progress ????? Pete

Pete Lewis Posted October 31, 2019 Report Posted October 31, 2019 the learning slows as the years flash by Ha !! remembering what you remember is another challenge now there's a shortfall in steam engine drivers , same applies to old school classic problems we need to pass on so much to the youngsters , who only seem to push buttons . how about a members apprentice scheme ??? pete
JohnD Posted October 31, 2019 Report Posted October 31, 2019 Seen in "Another Place", this is how you get a new battery:
Pete Lewis Posted October 31, 2019 Report Posted October 31, 2019 must have some tough fingers ???? just shows what can be achieved when H & S is kept away but where there's a will there's always ...a Way i guess this is ...inspiring !!!! Pete
Chris A Posted October 31, 2019 Report Posted October 31, 2019 Now children, don't try this at home. 😷 Back in 2003 when I spent a month in Cuba they repaired disposable lighters, amongst other things, in similar 'artisan' workshops. What went under car bonnets was 'enlightening'. We gave a couple of school children a lift in our modern hire car, they were completely amazed at the fact that the rear windows had winders and worked!
