Hey, after spending quite a bit of time searching over the past few weeks regarding an apparent electrolysis issue with my XJ I figured I'll just ask as I can't seem to find the answers to my question.
I have a 1997 Cherokee (4L, AW4, NP242 if this makes a difference) over the past year I've been having some radiator issues resulting in several replacements under warranty from my local mechanic (unfortunately I don't have enough experience nor the tools/space to do this type of work). They have determined it is an electrolysis issue causing the repeated failure of these radiators.
Though when I measure the voltage difference between my negative battery terminal and coolant overflow bottle I get a voltage reading between -0.1V and -0.2V depending on coolant temperature (Voltmeter's negative probe on neg battery post and voltmeter's positive probe in coolant overflow). Am I incorrect in thinking I don't have an electrolysis issue by having a - voltage reading, or am I measuring it incorrectly?
Thanks for your time!
