I don't even think that just a "pulse present" indicator would tell you anything useful
"need teach naked woman to spin" If you do not have the tools (I recall once on a software trip [no scope] being redirected to take care of a hardware issue) you must find a way to get by with what you have. My basic presumption is that if you can do something with proper tools in an hour, it should take no more than a week to do it without. A scope will tell you if you have the right thing a "pulse present indicator" will tell you if you have 'something' and then you must surmise if it is "the right thing". There is no way in hades to do hardware debug without a scope, so the amateur has two options: a) buy proven hardware e.g. SILabs devboards b) buy a scope Now to see if a chip is dead as a doornail (the original question) a "pulse present indicator" on ALE would, while not proving that the chip is functioning, show if there is any life.
