Turn Signal Flasher Relay

[Pipemasta808]

So here is an odd on. I have a relay 5 pin in my 71 and it makes a rattling sound when running at times in 1stand 2nd gear. Literally sounds like a rattler! Now, it functions okay... but it is annoying! Any suggestions on what gives, possible fix or even replacement. Below is the relay. I’ve searched and cant find a replacement readily available. Thanks!

I'd suggest opening it up - pretty simply mechanism, see what's loose, maybe fixable..

yes, that was the first thing i did, looks good from what I could tell...but that’s not saying much!

OK, another question, do you have LEDs? At least on other vehicles I have had, LEDs don't draw enough current to properly throw relays...

This lil piggy is nearly 100% original... so nope, old lights still in. I wonder if this relay also assists the Speedo

Afraid I am out - I should have in my signature line that I hate electrical issues, good luck though

Are you sure that's your turn signal flasher relay?
I thought to pigs had a three post flasher relay.

So I looked that up as well and saw that Speed Marker relay... and I wondered. so I disconnected the bugger and turn signals still work! SO! must be speed marker relay? Did t know one existed but makes sense it rattle at certain speeds? now for a replacement.....

Looking at the wiring diagram it controls a valve, taking a wild guess that valve is on your vacuum advance and pulls timing once you hit a predetermined speed, I would disconnect it and go for a drive.
