I don't think there is any way to remove the heater without taking out the dash and other interior items first. Dash removal isn't particularly difficult and with the steering wheel off and the hood down access is OK.

Location of hazard flash is shown on the top diagram from Revington TR in the attached sketch. From personal experience it can be accessed from below.. 2D-08L.jpg (JPEG Image, 829 × 1150 pixels) – Scaled (95%).pdf2D-08L.jpg (JPEG Image, 829 × 1150 pixels) – Scaled (95%).pdf2D-08L.jpg (JPEG Image, 829 × 1150 pixels) – Scaled (95%).pdf2D-08L.jpg (JPEG Image, 829 × 1150 pixels) – Scaled (95%).pdf

PS are you still looking for the owners manual for your car? Cheers Howard

Sorry to tell you, but it really is at the back of the glove box. I have replaced two of mine and they are in the same location on '81 cars. FYI I installed the replacement electronic flasher relay under the central console cover after extending the cables to simplify future replacement. I think I have a photo or two and a drawing which I can post if it would help.

Sounds to me as if there is a short circuit between the live feed and the casing which only shows up when the heater is in the car. If you have access to a multimeter measure the resistance between the 12v live wire and the case. If it's less than one ohm that is probably the root cause.

If you are driving the motorway in the dark you will miss breakfast .

Stuart. Start by borrowing a multimeter and check the resistance on your spare sender. As you move the arm it should change from 10 to 300ish ohms. If it changes and is within these limits you can use it to test the circuits on the instrument cluster. Connect the spare sender into the wires that are plugged into the existing sender. If the gauge still jumps to full irrespective of the position of the sender arm the problem is not with the sender. As I said before there has to be either a short circuit on the wiring (green/black wire) to earth, or a short on the printed circuit board or a faulty gauge. Check the wiring from the flat connector that plugs into the back of the instrument cluster and again the resistance should vary as you move the sender arm. If it doesn't and it shows a very low resistance the problem is in the wiring loom. If that's ok, see if you can remove the gauge itself. I have a recollection that this may not be as simple as it sounds, but if you can, carefully trace the connections by following the circuit board tracks from the guage back to the connector. Repeat the above test. If it passes the problem is with the gauge

I recall Rob Pearce mentioning something similar regarding the indicator circuits at the CT/TSSC meeting so hopefully he will be along shortly with a detailed explanation. Howard

When the tank is full the resistance from the level transmitter is 10 ohms and empty approx 300 ohms, so if the gauge jumps straight to full there is a short circuit somewhere in the wiring. A short circuit on the flexible PCB behind the instrument can be repaired so long as you are very careful ( I had to repair mine so it is possible 🙂 .) You may find the attached drawings assist you in tracing the circuits. Cheers Howard 1981 TR7 DHC Wiring Diagram Rev 7 03_2023.pdf

Danny, LED's are light emitting diodes so when you try to check the continuity there will only be a path one way. So there should be continuity between both contacts and the barrel so what you have measured is correct. I suggest you try the following:- Check the power feed to the bulbs. If you have a voltmeter check the voltages on the feed wires to both the side lights and the brake lights (with the side lights off) - you should see 12v in both cases. Unplug the both wires to the contacts only and with the side lights switched on connect each contact in turn with the sidelight supply - the bulb should light up in both cases. Repeat this with the brake lights & again they should light up in both cases. I cannot immediately see why you are having a problem, but I know that Triumph did occasionally use a return path through the bulb filament which doesn't work with LED bulbs without a small modification.

Enter this years C2C in June and enjoy driving the roads instead😄

👍

Have you tried turning it over the opposite way to how it fell and giving it a good bang to see if you can shake it free?

I have updated my wiring diagram and now include details of all the electronic circuits to facilitate repairs. Please feel free to redistribute it. Cheers Howard 1981 TR7 DHC Wiring Diagram Rev 7 03_2023.pdf

I have a Garmin 55 dash cam permanently installed on my TR with a 64GB card that records about 24 hours before it overwrites itself. The main point to decide is what do you want the camera for - to produce movies of the trips you have done like this one I filmed in 2017 10cr Stelvio at sunset or simply to provide evidence in the case of a accident / incident. When I wrote off my car the camera provide evidence to the insurance company that I was driving sensibly and something failed when I was doing a pre-MOT brake test. Look at the on line reviews before deciding, particularly the following points:- Resolution. You need a decent lens with high resolution to read number plates, but the higher the resolution the larger memory card you need. Night vision. Reflected glare from road side signs can make it difficult to see the road so the dynamic range it important. Recorded data. If you look at my video you will see that it does not display the speed, only time and date. If you post the videos or are involved in an accident the police & insurance companies may take an interest in the speeds you were doing long before the accident (it is possible to calculate the speed from the on screen times and by physically measuring the distances between two points, but this requires significant effort) What software do you want to use with it? Garmin used to provide a program that allowed you to look at the recorded videos while simultaneous plotting you location on a map.

I had a few minutes free to check at the How Many Left / DLVA web site and was pleased to see that the numbers of taxed & insured TR7's have been steadily increasing over the last ten years. In 2005 there were 1300 left on the road (excluding SORN'd cars) and today there are 1346. By comparison, the lowest number recorded was around 2013 when at one point the total was just 646. The web site engine size tab also records that 300 of the currently taxed cars have had larger non-standard engines (probably Rover V8). There are some obvious errors since it appears that according to these records there are also 23 that have replacement engines of less than 800 cc installed! Has anyone checked the other Triumph models?

I read this and fell about laughing. Whatever will the Yanks shoot down next! Santa needs to be very careful next Christmas since he is already tracked by NORAD.. From Aviation Week Network: "A small, globe-trotting balloon declared “missing in action” by an Illinois-based hobbyist club on Feb. 15 has emerged as a candidate to explain one of the three mystery objects shot down by four heat-seeking missiles launched by U.S. Air Force fighters since Feb. 10. The club—the Northern Illinois Bottlecap Balloon Brigade (NIBBB)—is not pointing fingers yet. But the circumstantial evidence is at least intriguing. The club’s silver-coated, party-style, “pico balloon” reported its last position on Feb. 10 at 38,910 ft. off the west coast of Alaska, and a popular forecasting tool—the HYSPLIT model provided by the National Oceanic and Atmospheric Administration (NOAA)—projected the cylindrically shaped object would be floating high over the central part of the Yukon Territory on Feb. 11. That is the same day a Lockheed Martin F-22 shot down an unidentified object of a similar description and altitude in the same general area. There are suspicions among other prominent members of the small, pico-ballooning enthusiasts’ community, which combines ham radio and high-altitude ballooning into a single, relatively affordable hobby. “I tried contacting our military and the FBI—and just got the runaround—to try to enlighten them on what a lot of these things probably are. And they’re going to look not too intelligent to be shooting them down,” says Ron Meadows, the founder of Scientific Balloon Solutions (SBS), a Silicon Valley company that makes purpose-built pico balloons for hobbyists, educators and scientists. The descriptions of all three unidentified objects shot down Feb. 10-12 match the shapes, altitudes and payloads of the small pico balloons, which can usually be purchased for $12-180 each, depending on the type. “I’m guessing probably they were pico balloons,” said Tom Medlin, a retired FedEx engineer and co-host of the Amateur Radio Roundtable show. Medlin has three pico balloons in flight in the Northern and Southern hemispheres. Aviation Week contacted a host of government agencies, including the FBI, North American Aerospace Defense Command (NORAD), the National Security Council (NSC) and the Office of the Secretary of Defense for comment about the possibility of pico balloons. The NSC did not respond to repeated requests. The FBI and OSD did not acknowledge that harmless pico balloons are being considered as possible identities for the mystery objects shot down by the Air Force. “I have no update for you from NORAD on these objects,” a NORAD spokesman says. "

I largely agree with Tim, in that a period program should be fundamentally correct. So long as they have made a good effort to replicate the correct era I can accept that compromises are required, but where a program dismisses this and shows multiple incorrect items that would not have existed at the time it destroys the whole drama for me. P.S. In model railway terminology anyone who is overly pedantic about accuracy is called a "Rivet Counter" - the sort individual who complains if the number of rivets on a model is not exactly correct. Some rail modeller even run modified wagons fitted with a radar antenna on the roof to detect/annoy River Counters!

What's a Triumph Ajax? 😄

The camera is permenatly fitted to the car. H

Hope to share a few beers with everyone on Sunday night after the RBRR again H

Have you tried a different browser? Eg Firefox to see if the issue is the Samsung version of Android or the browser.

Keeping to the wedge theme, here is my S+S 1991 conversion TR7V8 taken yesterday. Its parked in front of Lake Vyrnwy dam during a recce for this years Coast 2 Coast run.

Drat, I didn't expect anyone to recognise the Welsh Motorway. ,😂

Welsh motorway?
