speed warning buzzer

[Keith B.]

I bought a NOS buzzer and it does not work. is there any way to make them work again?

Keith,

It may be just a corrosion issue on the internal contacts.

Carefully pry out the cover tabs, remove the cover to expose the contacts. Clean them with a points file.

It could also be a broken coil wire. That would need a delicate soldering repair.

If you open it up take a few photos from different angles.

I did and it's clean as can be.

Ok, put a ohm meter across the coil wire terminals. One side is power(Org). Its ground comes from the speedo head terminal(-) below. Should get a ohm or less.

Short meter leads together first to get lead error. Subtract that from the 2 terminals(+-) reading.

If the coil tests good, try this......
