What ever the value - make a set up to be one if need be.

If you want a large value - Rtotol = R1+R2+R3..... when in series.
-/\/\--/\/\-/\/\-....

If the value is small - you can parallel them together for a smaller one.

so all ends are together on one side and the other side all ends together.
Make a pigtail if needed - but they become series resistors then - the leads.

If you want to make a 47 millohm - sounds like a sense resistor.

If this is a tube circuit - it would be k or meg for most -

It would be best to tell us the circuit that that part is in. And where.

Transistor / triac / tube - and where the part is .

Low values can be made from large fuses that are trimmed down to increase value.

Hi Friends,

I'm trying to help my Italian friend sort out an electrical problem
with his Bridgeport mill.

Please excuse my inexpertise in electrical terminology. I am just a
friend trying to help him

out as he doesn't speak english and there is no Bridgeport support
here in Italy. This is

what I know about his situation:

1. He has a "burned" resistor (I think that's the right term) on his
"FEED CONTROL" circuit

board. It blew and there is a heat marking on the board where it was
fried.

2. The resistor is marked R6 on the board, which corresponds to the
wiring diagram.

3. The photos illustrated show the basic type of mill (Bridgeport 2HP
model), the electrical

panel, the position of the electrical board for the feed control, the
position of the board,

and the general electrical layout.

4. The mill was manufactured in 1979 and the serial number is 7978.

The resistor was burned and there is no visible markings or colors
with which to reference.

He is asking me if anyone knows what the resistance capacity is (in
ohms??) so he can

source a new one.

Can anybody help two lost souls? Sorry again that I'm not a machinist
or electrician.

Thanks so much for reading and we'd really appreciate your help.

Ciao,
darren
R6 shows as 47 Megaohms on my schematic.

cheers
T.Alan


milliohms maybe?
