How can it be determined if the primary dash grounding plate behind the instrument panel is itself properly grounded? (kind of like, 'how can you know if a level is level')
Can the radiator coolant mix solution be determined with a refractometer? If so which brand and model # would be adequate? Don't want a cheap one but don't need the best either.
Thanks, Gary
Gary,
Here is a link to the refractometer that I have used for years. Simple to operate. Most Accurate Fahrenheit ATC Glycol Antifreeze/Battery Fluid Refractometer... (http://www.opticsfactory.com/most-accurate-fahrenheit-atc-glycol-antifreeze-battery-fluid-refractometer-tester-rha-100atc/)
If you use one of these remember that all you read is freeze protection, you still need test strips to read nitrates and pH.
We don't get a Kick back from these people just an example as to what we use. You may even be able to find them on eBay.
