I am just having no luck with these things. I have purchased a few that have worked to some degree but have ultimately failed in the end!

One that works please.

I have several. Can test them when i get back home in a week.

Thanks Bruce. I am not in a hurry.

Mike, drop the port end of the AAR into a small soup can (or similar vessel) and pour in enough solvent to fill the ports. Let it soak for a day or two, then apply a 12v power source to see if you can get the plunger moving. Repeat the process a few times and it should be good to go. The cleaner you can get it, the better.

Hmm. Where have I read this recently?

Good luck! I'm still working on mine. Results still inconclusive at this point.

Perseverance ...
