[TR] TR3 Horn Relay

[Kinderlehrer]

Terry,

The points tend to wear over time and require some adjustment. Remove the dome and you will see them. I don’t remember the specs and I can’t find the reference off hand, but it is important that there is some gap however small. It is easier do if you remove the horn and work on it on the bench, including a power supply to test it. At least that’s what I  remember.

The horns on my TR3 are less than useless, giving out this embarrassing thrush-like warble like I'm taking revenge on some meathead driver who just swerved into my lane to cut me off by tweeting at him/her.  

 

Take that, you poo-poo head!

 

I might just as well stick out my tongue at them.  Makes the same amount of noise....

 

So, I have solid ground and good current going to the horns.  I seem to remember having to tune similar horns on my old MGB 45 years ago but can't remember if these are set up the same.    And I can't remember if there's a relay in the horn circuit for a TR3.  Since it's freezing in the garage here in New Hampshire, I'm too lazy to dig out my electrical diagram there.  

 

Thoughts, anyone?
