Where do you find an in-series "test" tool for relays to probe each post of the relay while it is installed. The ones I've seen are blue, and you plug it in where the relay goes, then relay plugs into the top of it, leaving the tabs exposed so you can aligator clip onto them. I have a bunch of relays clicking on my durango and it won't run. need to see what is happening.
Cuz I'm not testing whether or not they work. More to see what voltages are coming in and going out. and what'* happening when things are going haywire. With no relay - the circuit is open and will test different then when installed.
Amazon has the group w/o pliers listed for $120
