I recall the heater not hooked up on the 82. A compression test is a great Idea....no sense in replacing my 20R with a 22R that is dieing....although, it felt stronger....seat of the pants feeling.LOL
I was thinking along the lines of wireing issues. Do I keep my 20R wiring or replace the wiring from the 82...I think I would have to pull all of it out(82)?
I know it's early..or late depending on the time and location of everyone. I still need to go pick her up.
Thanks again,
Mike
