Since the OVP acts like a smart fuse, the easy way to evaluate it is to see if the devices powered by it are functioning. Not functioning right or wrong; just functioning. Just as a fuse can't make a system perform wrong, only not at all, the OVP either does or it doesn't. A standard voltage drop test is the absolute answer.
That makes sense alright. Whats a voltage drop test (remember, I'm an idiot!) and which devices should I test and how (remember, I'm an idiot#2)?
