Last fall I put a Premier Power Welder on the jeep. Since the install I've had a slew of odd electrical behavior. Some could simply be coincidence - but the coincidence list is longer than I'd anticipate.

I've spoken with the company and they are willing to help but have not heard of or encountered such problems. I purchased a replacement / backup regulator-rectifier and the same performance is noticed.

I'm wondering if the PPW system is putting out some stepped or noisy power to the jeep's electrical system.

I don't know if an oscilloscope is the proper tool to measure the condition.

Thoughts?
