Electrical: What is this relay good for?

[TR3driver]

I disagree, I don't think the glowing has anything to do with a bad ground. That is the connection between the solenoid and the starter, and the glowing indicates a bad connection at that point. Possibly just tightening the nut will work, but I would want to disassemble the joint and clean or replace all the surfaces involved.

The starter draws something like 500 amps at first, so good tight connections are essential. And that hot spot will eventually burn out and quit working altogether, no doubt at the most inconvenient time. The strap into the starter is the most likely candidate for burning away, which will ruin the starter.

Adding a ground connection between the engine and body/frame is certainly a good idea, as otherwise it will be something like the choke cable carrying the current for the lights, etc. But I don't think it's the source of the glow shown above.

They corrode.

They are also very easily damaged by a short in the instrument lights. Even if you want to retain the rheostat function, I would suggest temporarily bypassing it and driving the car for a few nights, to be sure that's not why the old one failed. It makes a VERY expensive fuse !

On my Stag, the intermittant short proved to be the wire to the gear indicator for the automatic transmission (unused since my gearbox is manual), which was pinched between the console and the tunnel. Obviously doesn't apply to a TR6, just an example ...

I'll do that. And later by-pass the reostat.
Anyone knows how the knob to the the windscreen wiper on a 73 is supposed to work? Puss/ pull or turn right/ left?

Get comprehensive insurance coverage on this fire trap BEFORE it burns to the ground(not after,its fraud)...if you like the car get an extinguisher too. This car is going to need a lot of TLC and $$$$ Good luck!!(you will need it)

You need to take the connection apart that is glowing and clean the corrosion off of the parts. You have a high resistance connection.

Sorry, I don't. Might be best to start a new thread, as I'm sure someone does, they just aren't reading this thread.

However, did you know that TRF sells reprints of most of the factory owner's handbooks?
For a 73 with carbs, I think you'd want P/N 545111/73 which is currently on sale for 13 USD.

Hello Anders, I have your same problem, painted cables,missed fuses, and new cables added,this is the sindrome of the bored Triumph owner, thank God here we found LBC lover owners and ready to help us, ask tinster, he can tell. I was working on my electrical system my car comes with a siren, air horns, a on/off dimer swicht, early alarm system with on/off switch, cb radio also a loudspeaker, I dismantle all start puting all cables back to the original way, now the original horns,the original dimmer switch(ebay),the courtesy lights,the buzzer for the seat belts,the glove box light, the trunk ligh all this are working fine.The next is the reostad, the temperature gauge and the gas gauge, this is not working, maybe because I loose some cable. So take your time and ask this guys they're always here to respond to our prays.

Gardener,

Check the voltage stabilizer on the back of the speedometer for the temp and fuel gauges. https://www.74tr6.com/gauges.htm

Here is how to rebuild the rheostat. https://www.74tr6.com/rheostat.htm

Good luck,

Paul

I bought the Hand Book today. The PI version though, but for most practical purposes it seems very useful. As late as Dec 05, the original Hand Book, tool kit etc. followed the car, but somehow seems vanished during the last two years.

And Mad Dog - extremely encouraged by your prognosis. But I'll certainly get an insurance and distinguisher.

Couldn't agree more. Luckily, my car hasn't been fitted all these strange extras, but nevertheless the wires and cables do not look very simular to pictures from the average seasoned TR. My gauges are working surprisingly good so far, no lights in them however. As soon as more critical issues are solved, I'll start with the rheostat. And then clean off the paint on several wires with aceton or nail polish remover.

Is it going well otherwise with your car? Made some test runs, keeping pace with Amos?
