Help! How Do I Detect Stray Electrical Current In Coolant?

[GTR_26]

Hi all, I have searched in various sections but cant find anything and my apologies if this has been discussed before....

I have just installed a new alloy radiator in my R34 and want to make sure it doesn't have stray current running through the coolant which may harm my radiator. Has anyone had experience with this? I have a Digital Multimeter but am unsure of what setting to have it on etc. Any help in regards to this would be greatly appreciated.

Thanks, James

couple guys from work have just been through this at work recently on a grader with bad samples after a service. they set the multimeter to volts and measured between engine block and other probe suspended in coolant but i cant remember how much voltage is acceptable. will try get back to you tomorrow with a figure but i guess if you test and have 0.0 volts then its sweet
