Radiator voltage readings
I just tested the voltage between the liquid and radiator in my brass Brassworks radiator (.18v) and aluminum Griffin radiator (.14v). Did I do it properly and if so are the readings acceptable? Thanks

Re: Radiator voltage readings
Of course the readings have to be compared to the chemical make-up of the liquids in the radiator. What were the results of the chemical analysis?

Oh Oh, you are talking above my pay scale now. lol Don't think I've heard about that before.

Re: Radiator voltage readings
Here is a good description for checking for electrolosis, although your readings look acceptable.

Re: Radiator voltage readings
Try grounding the radiator real good.

Re: Radiator voltage readings
Is it a 6 volt radiator or a 12 volt? Did I really ask that question? Sorry senior moment.

Re: Radiator voltage readings
I find this to be shocking!

Re: Radiator voltage readings
And why exactly do I/we want to do this?

Re: Radiator voltage readings
Probably to check the Ph of the anti freeze to see if his radiator is being "dissolved" due to electrolysis.

Re: Radiator voltage readings
Words of wisdom from the late, great Rumbleseat:
CHECKING COOLANT FOR RUST INHIBITORS AND THEIR CONDITION: As we all know, anti-freeze never loses its anti-freezing ability. It may get dirty, but it still has the same anti-freeze characteristics as when it was new. HOWEVER, the inhibitors last only a fairly short time. The most common solution to this problem, and I think what the manufacturers want us to do, is to replace the anti-freeze. But why not just replenish the wore out rust inhibitors? Problem is how to determine the inhibitors are no longer active. Remembering our old high school physics..... Whenever dissimilar metals are immersed in a liquid in motion, D-C voltage will result.... or something along these lines. This will cause softer metals (like aluminum, zinc, brass, and copper) to transfer to harder metals by electrolysis. Inhibitors prevent this by reducing or eliminating electrolysis. Determining the condition of inhibitors can easily be checked using a Volt-Ohm-Meter (VOM). A digital VOM is easier to use than an analog (analog have scales and a needle) for this test. Turn the function selector to D-C volts. You’ll be measuring voltages of less than 2 Volts so select a voltage of 5V or less. Hold one of the probes (either one) suspended in the coolant in the top radiator tank. Don’t let it contact any metal. Ground the other probe to the metal of the radiator filler or tank. Read the voltage on the VOM. When the voltage exceeds 0.5 Volts D-C, the inhibitors are worn out and are no longer doing anything. Adding a can of rust inhibitor is all that’s required. A voltage reading of 0.5 Volts DC or less show the inhibitors are still active and there is no need to replenish them. Remember, anti-freeze never loses its anti-freeze capabilities...... it only looses its
