I'm attempting to remove rust from some parts using the washing soda/battery charger method, but I'm running into a problem. My charger is too smart for it's own good.

It has a circuit to detect if the battery it's connected to is no good. If it ain't, it shuts down. Well, since I'm not connecting it to a battery, it shuts down.

I'm using a Husky charger from Home Depot. Glancing at the shelves of the auto parts stores, it would seem this is a common feature. Anyone know how to fool the damn thing so it starts shooting the juice through my contraption?

Check out some local garage sales or on craigslist.

I have 4 older craftsman models that I use for both stripping and anodizing. $20 for all of them.

Yeah, guess I'm going to have to find an old one.

If I had a car battery lying around, I suppose I could put it in series with the charger and rusty parts, but I don't.

I got one of those smart sears chargers for xmas $80.00 I think. The first time I tried jumping my garden tractor with a flat out dead battery it did nothing. I guess they need somekind of read back to work plus it had all kinds of crazy ass read outs on it. I ended up returning it and found one (old) at a yard sell for $5.00 6 or 12 volt and a on and off switch and it works great. Just simple and works the way it should.

The link in my original post is pretty straight forward.
Just make sure the charger you use doesn't have a bad battery sensor.

It works great! You just have to let your rusted pieces soak in the mix awhile.
