A simple idea to try
 

I have been reading on this forum for a while... finally decided to register. I ran into a guy who made this video. I have tried this myself on my Astro, No concrete results yet but some interesting things happening with my multimeter. I ran the wire into my coolant reservoir and gradually saw an increase in voltage at the battery. The coolant also held a charge of 2 volts for about 5 minutes gradually tapering off. I ran the van for a few minutes until the voltage climbed and added fresh water to the reservoir and the voltage at the battery dropped a volt with the van running. I figured with the cumulative knowledge on this site as well as your scanguages we may be able to explain the results? It would also be great if others would try it and share there result if any? I figure worst case we end up with a really good ground to the block?

Cute picture... but what are the reasons you discount it? Care to educate? I am not saying that I believe in it 100% but I am willing to try it. I am skeptical of everthing myself Including conventional wisdom :)

Doesn't look that way.

oh come on frank lee........5 minutes counts as 'a while'!!

Wow tough crowd... I said I have been reading for a while but I just registered...

welcome!

We really believe in testing.
ABA testing is the standard.
you can search and there are several posts on how it works.
instead of a lot of posts about how a poster 'feels' about something (which is a waste of everybodys time), we look for factual, tested results.

I like how it will not work with vehicles that o2 sensors so you can't hook it up to a vehicle with a scan gauge and prove that it doesn't work right there!
I bet that if the wire was replaced with a piece of string that guy would have seen the same results.

...provided it was done without his knowledge. Placebo requires an uninformed participant.

...but, unfortunately, we (america) got lots of them!
