Hey,
So, I'm trying to ID the components on the board of my cars cruise
control board (it's broken). Now some I know, like a component with
"R43" next to it is a resistor, or "C12" is a capacitor, "Q16" is a
transistor, and "D1" is a diode. But here are a few I don't know and
would like help IDing:
"RA3" -
"X1" -
"IC7" - (integrated circuit?) -

That's it. School me!

Thanks,
Paul B.

TR is frequently used too.

Might be 'resistor array' as in a SIL or DIL resistor pack. I use RP for that.

> "X1" -

crystal

> "IC7" - (integrated circuit?) -

Yes. The designation U is also used too for ICs.
