Also keep in mind that voltage drop is a variable and is a function of load. So it's not something that can be measured except during those times when it's actually happening.
Measuring the voltage at the input to the unit's engine battery connections won't show a dropped voltage if there is no load to pull the voltage down.
There probably won't be enough load to cause a voltage drop if A) the house battery is full, or B) the unit detected a voltage drop and stopped loading the input.
The CTEK probably responds very fast (solid state switching) to a dropped voltage on the input, so even if you do have a voltage drop issue to the unit's input, you might have a tough time actually catching it at the right moment to see it on your meter.
Edit: And it could also happen so fast that your meter's display can't keep up. So even if the meter could see it happening, you might not.
