Im stumped on two capacitors I can't quite figure out their size.
They are small capacitors
One side has
470
A1J
the other side has
804
AGC
Is this one 470 micro F

The other one has;
235
RCV
the other side has
4R7
A2D
And is this one 235 micro F

Thanks

That's an odd value, 235uF...not impossible, though.

How is it shaped? 4R7 means a 4.7 ohm resistor, usually.

I might guess that it is 47 pF (4, 7, and no zeros) - but I might vary
my guess based on the size of the capacitor.
As another poster suggests, 4R7 suggests a 4.7 ohm resistor.

235 doesn't seem to be a value - "23" isn't a standard value, but "22"
is - 225 would be 2.2 uF

You will only rarely see capacitors or resistors with values specified
to three digits.

They are both a sort of gold/orange. Both are small perhaps a little smaller
than a grain of rice. The 4R7 is a little more square than the 470. Perhaps
I will try putting the one that you both think is a resister on the ohm
meter and see if it reads the right amount. The reason I thought they were
capacitors was that they look like the same kind of packageing and color as
other capacitors I have.
