Macintosh IIci 5V to GND resistance?

[DevyDevly]

Hi,

Can I ask a favour please?
Can someone with a working IIci please measure the resistance of their 5V rails to GND (e.g. the positive side of C14 to Ground).

I'm trying to fix up a IIci but not sure whether the 16-20ohms I'm getting is normal for the IIci - I've seen a few posts online, but nothing definitive.

Many thanks in advance,
G.

I get 13.8ohms steady on my working IIci.

Though I don't have a board to hand to measure a exact value I can also confirm sub 20ohms between 5V and GND is totally normal on the IIci. This threw me the first time I saw this but I have verified it against multiple boards and it's totally normal

Many thanks Eric!
Looks like I can eliminate this as a source of problems.

It’s definitely thrown me too.
