Ammeter heat question

I decided I wanted to do the easier ammeter bypass in my 67 Sat by bolting together the feeds and taping up really good.
My question is would you expect them to get warm?
Roughly, 100degs?
I would expect due to resistance in the system, some heat is expected, but it surely is not enough to melt anything and would be the same even if it was left hooked up to ammeter.
For just this modification, would leaving these taped up behind the dash after experiencing this 100deg or so warmth be acceptable?
