Alternator question

I have appointment tomorrow to get new tires, about 6 miles total driving. I don't want to re-schedule appointment as I need m/h next Monday.

But I'm waiting for elec part to come in. The part is what is called "shortstop" and I couldn't find any locally. Right now my pos and neg are disconnected at house battery and at the converter. All metal ends of battery cables taped up, so no contact with metal.

Question...When driving it, will the charge line under hood sense no power and do damage to alt? Or will charge line sense circuit is not complete not put out power?

Your alternator is (or at least should be) connected to the chassis battery, not the house battery directly. It will work just fine, exactly as though it were an ordinary truck without the motorhome stuff attached at all. No troubles with driving across the country, much less a few miles.

A tiny caveat: Sometimes weird wiring things are done to RVs, particularly by (prior) owners who thought they had some idea what they were doing but in actuality may not have. Still, having the alternator sensing voltage at the missing house battery would be very very much unexpected and would tend to be problematic in other ways even if the battery were installed and connected.
