Review on ⚡ Dorman 86579 Electrical Tester - Inline Spark Plug Diagnosis Tool by Jeff Addison

There were big problems with the outboard motor. It is difficult to pull the starter cable and at the same time try to hold the spark plug (either one) to the engine ground and try to see if there is a spark. After buying a spark plug and a wire tester (which I should have bought sooner), checking the spark was easy. A spark or fuel problem was immediately identified. I think this is the tool that I think most mechanics should have in their It's worth every penny and I highly recommend this Revain CharlotteNC reviewer
