JohnD Posted August 25, 2022 Author Share Posted August 25, 2022 (edited) The race is looking to be a corker! Entry list shows 16 Gp2s with eight Ginettae/Loti, who usually zoom off and have their own race. Leaving three Reliant Sabres and FIVE TRiumphs! No seven litre Camaros etc, who lap us, just a TR6x2, TR5, TR4 and me! Should be a very Triumph race! So many from Gp1 have entered the meeting that another six of them have been appended, which will add to the fun. Hope to see you there!

PeteStupps Posted August 25, 2022 Share Posted August 25, 2022 I'm seriously considering driving up to watch John. But it's a bit of a trek from London so not certain. Trying to rope a mate in to share the driving Link to comment Share on other sites More sharing options...

Escadrille Ecosse Posted August 25, 2022 Share Posted August 25, 2022 Sounds like an excellent grid. Good luck and enjoy Link to comment Share on other sites More sharing options...
JohnD Posted August 25, 2022 Author Share Posted August 25, 2022 (edited) Pete, I might be at Donington on the 10th, I will be at Kop Hill on the 25th - the last is lot nearer London! Michael, O/d electrics check out, the solenoid moves correctly, I even checked the oil filter, all clear (but half a gear boxful of oil on the floor!) So if it works, it works, if not higher revs! I can't investigate, or fix, anything else! Rev counter also failed last test drive, but it was just the earth wire had fallen off the gauge. But all that and it was too late this evening to disturb my neighbours with a test run, I'll go tomorrow. Hoping for a H-A-P-P-Y like Ken Miles in the film! Colin, CSCC has been known to go to Knockhill - I will let you know! John Edited August 25, 2022 by JohnD Link to comment Share on other sites More sharing options...

JohnD Posted August 26, 2022 Author Share Posted August 26, 2022 Now I realise that I am becoming the Moaning Myrtle of Hogwarts Sideways College but these Common Room discussions are so helpful! This time, I'll be grateful for the help of the Electrical Engineers, please! Test drive today - A-OK! I can't get the O/drive to work, maybe it suffered in my previous stressing of the box (don't test run the engine without oil in the gear-box - Doh!) but it's not essential, just helpful. Everything else works! Except for the horns. Once again, not a necessity on track, but the car is supposed to be road-legal and I test it on the public highway, so a good thing to have. But all I get from the horn push on the steering wheel is slight fluttering from the horns. OK, out with the multimeter. Two horns, Hi-Tone and Lo-Tone, wired in parallel and always live. Both should get 12V, and they do! Downstream of the horns goes to the 'pencil' in the steering wheel hub, and there's a full 12V there too. That contacts the horn button in the wheel hub, which makes a good contact when you press it, to earth the circuit via the steering column The column has a good earth. The horns should sound together, but they don't! Earthing the horns directly to an earth bolt in the bulkhead, sounds both. And individually too. But earthing the 'pencil' in the hub, sounds only the Hi-Tone horn. Using a short wire to connect the 'pencil' and the steering column gets the same Hi-Tone only. As does pressing the horn button in the usual way, just the Hi-Tone horn! And that is iffy. I'm thinking there must be a poor contact somewhere, with a high resistance that reduces the volts available at the horns. But each part of the circuit seems fine. Suggestions, please, for further investigation? Thanks, John Link to comment Share on other sites More sharing options...
Escadrille Ecosse Posted August 26, 2022 Share Posted August 26, 2022 Experienced exactly same John. Crud builds up on the brass ends of the pencil and brass contacts on the push and column ring. A de-fluff and buff up of these and making sure all the bullet connectors are tight does the job. Usually. The other one I used to get on the old Mk4 was hitting a bump and the horns sticking on due to the sliding joint sliding and shorting out the push. Very embarrassing.

JohnD Posted August 26, 2022 Author Share Posted August 26, 2022 So just go through the circuit and clean up the joints? Use brake cleaner spray, unmake, make and repeat, on all the connections? Link to comment Share on other sites More sharing options...
Escadrille Ecosse Posted August 26, 2022 Share Posted August 26, 2022 I found that the connection is in the column generally needed a proper clean which is cleaner and deoxidise with some abrasive Link to comment Share on other sites More sharing options...
flatter4 Posted August 26, 2022 Share Posted August 26, 2022 Agree the pencil is the likely culprit. Clean and clean again. Make sure the brass protrudes beyond the perspex outer at the bottom (top?) end. Also don't overlook the earth strap around the rubber universal joint. I think your circuit does not have a relay? If it does the contacts might benefit from a clean. Definitely a poor connection somewhere, the horns draw a large current so will expose a weakness. Unfortunately can't make it over to watch you this weekend, but have fun Link to comment Share on other sites More sharing options...
PeteStupps Posted August 28, 2022 Share Posted August 28, 2022 Strange coincidence but my O/D stopped working last weekend, definitely an electrical fault because I could hear the relay clicking but no power was lighting the warning lamp (which picks up 12v at the O/D solenoid). Then yesterday I found the horn wasn't working either. Which was good news because it meant a fuse had blown, and indeed changing the fuse solved both problems. But that evidently isn't your problem John, unless you've somehow got the low horn fused separately from the high, which would be unusual. Link to comment Share on other sites More sharing options...
Nick Jones Posted August 28, 2022 Share Posted August 28, 2022 Sounds like you may have a number of high resistance points adding up. Horns pull a fairly high current so volt drop can be a problem. Earth path, or lack of, from the column can be the problem. From the factory cars had an earth link strap on the flexible coupling (not needed if using a UJ) and an earth strap from rack to chassis. A multi meter test in this situation is only partially useful as although it proves some continuity, it doesn’t prove the circuit can carry current. You need a high ish wattage test light for that (old headlight bulb for example) Link to comment Share on other sites More sharing options...
JohnD Posted October 20, 2022 Author Share Posted October 20, 2022 Weekend after next, 29th October, I'll be at Cadwell Park in Lincolnshire for the last race of the season, and my first after the revision of the fuel system. And a spare gearbox! I have three spare tickets, if any Triumpheroes would like to come along. Please PM me? The programme includes Lotus Sevens, and clones, Modern/Future Classics, and Swinging 60s Groups 1 and 2 (Two races). Gp.1 practices at1020 and races at 1520, Gp.2(mine)at 1140 and 1710. 30 minute practice, 40 minute race, with pitstop. Glad of assistance with that if anyone would like to take part.

JohnD Posted April 9, 2023 Author Share Posted April 9, 2023 (edited) I posted about the Cadwell event elsewhere: Cadwell Park 2022 - Events and Motorsports - Sideways Technologies (sideways-technologies.co.uk) Now, I've entered for the CSCC's Thruxton event, 7th May. Nick will recall the debacle last time, two laps of practice and a burst engine, so I'm spitting in the Devil's Eye and he can do his worst! I'll report here later. That's a rising, not a setting sun! I'll be glad to see any Triumpheroes there! John Edited April 9, 2023 by JohnD Link to comment Share on other sites More sharing options...
rogerguzzi Posted April 9, 2023 Share Posted April 9, 2023 Hello John I hope you have better luck this time I still think of the the time we met at Mallory park with my late best mate and we fumbled with your seat belt as you had get out and back into your car in the race and Me and John were like laurel and hardy! But it was fun is that not what is about? And as my old Mother used to say there is no pockets in shrouds or similar! Me and the Memsahib are off the Spain again in about 8 weeks ! The first half will be seeing castles etc then the second bit Pyrenees We will have the useiual arguments over map reading or lack of it but a bottle of Fizz and maybe a leg over will get over it! It is just life ? Roger Link to comment Share on other sites More sharing options...
