It's possible your cell has frozen (or worse).Shocked

If your temps are approaching or below zero (like here), that cell belongs on the bench until you have a winter electrolyte.
I'm running 50% distilled white vinegar, 25% Di H20, & 25% Propanol as an antifreeze. I thought that should do it, although the spare fluid jug in the garage is a bit slushy. If the cell needs to be thawed, will it work again then, or will it need a rebuild?
My multimeter goes to 10 amps. I admit I forgot to change to lead from the 400mA post to the +10 A post. My bad. Blush

RE: weird codes
As long as it doesn't freeze solid you might be able to pull it off.

I've got a bottled water in my truck and the bottom is bulging so it's round on the bottom like a tennis ball. You said it was "colder than you know what" so I assumed it was highs of zero or less like here.

stl_hemi's right, if your cell isn't producing, you should pull it until you get it figured out.

I had a chance to drain the electrolyte yesterday, and as a lousy XMas present, I could see through the top plug hole that 3 of the plates are touching each other. Shocked No wonder there is no gas production. I have an email in to the local MagDrive rep to see what their warranty covers before I pull it and try to rebuild it myself.

Oh no. Not another MagDrive failure! I got a bad feelin' for ya gal! You might pull it, take and post pics for the folks to suggest fixes. Or, it sounds like you can probably handle that yourself.

RE: weird codes
I suspect damage due to freezing isn't covered.

MagDrive in GA got back to me to say that the 3 center plates are fused together on purpose. I rechecked the fuses and the 30a one was fried again. I think I am doing that when I try to check the amps coming off the block, so I have given up on that. I did do an H2O displacement test and am getting about 62 ml per minute. It took 8 minutes to empty a 500 ml bottle! Mad I guess some gas is better than no gas (depending on the sourceWink ).

RE: weird codes
You're not the first to note that their Magdrive produced less than advertised.

RE: weird codes
Please tell me you meant 620 ml/min? And THAT would be a bit poor, even for a brickinnabath type unit!
well, maybe something could be done with it to salvage it. I hate that for ya.

RE: weird codes
At 62.5ml pr min. you may as well just turn it off and put it on the shelf. Sorry for your luck. Build yourself a dry cell and you will have less problems and a better producing cell.

Let me put it this way: It took 8 minutes to empty the 500 ml water bottle.
I will have a serious talk with the MagDrive folks tomorrow.
