[RE-wrenches] for all you Aquion installers

[Tom Duffy]

We have a situation with a customer's Aquion (Understand there's now longer a warranty) I spent some hours looking at the Aquions. I tested the voltage of each cell. 4 out of the 6 stacks  had a cell that was low, in the range of 0, 3, 4, volts, while all the rest were above 6.

Each of the cells has a test point above the connector. The cells that were low each have corrosion on the positive terminal, such as you see in the photo. Any ideas as to what is causing this? Has anyone seen this before?


Kind regards
