Charge in Radiator

[punisher72]

Hey guys n gals.
Ive installed a Alloy Radiator and i have a charge running through the coolant when the car is running or not.
Im told if this is the case the radiator will eat itself 
Can anyone tell me how i could fix this?
I dont know where to start 
Thanx in advance

Found a couple of articles, each suggest eliminating possible sources and adding back one at a time till the issue reappears.
One suggests missing grounds even to the radiator.

Now we all know why it is so important to flush out the cooling System in your newer car every 1-2 years.

Afterall, where does the Spark energy ground when that 50K volts goes through the spark plug?

Right through the coolant, to the block, to ground.

Spark would go from the center electrode to the block to ground. The better your ground wiring, connections, the less current will look for pathways elsewhere. I'm curious though. How do you measure a current flow in your coolant? Water, coolant will always have a certain amount of ionized molecules, so there will be some 'charge' no matter what.

take a volt meter put the black lead on the negative battery post and put the red lead in the radiator neck touching only the coolant with the engine running. my 02 dakota had a bad ground and it ate the aluminum radiator up in short time. new rad and cleaned grounds later it is good to go.

I was talking to a mate today and he said to go over my earths from motor to chassis.
I have an earth from front of block to k-frame only.
Im going to add 1 from rear of block to the firewall and recheck the earth to floor in my boot.

When i checked my current in my radiator with everything running it was around 0.066 volts.
Im pretty sure it should be no more than 0.05........

Had a radiator eating issue in one of my excavators a few years ago.
Didn't worry me too much as it was warranty.
Anyway,after the 3rd radiator Komatsu looked further into it and yes,the culprit was poor earthing.
Komatsu says absolute max 0.04V.Desirable max 0.015v

The block to chassis ground wire should be a substantial wire, like #4 AWG (or better). Same size as the one connected to the -ve post on your battery.
