Review on Power Probe PP319CARB Carbon Special_Use_Testers by Guled Probz

The thing works great but you have to be careful how you use it. I've found that partial tribes don't always read well. Also, do not use a driver with a pulse width driver. I checked the camshaft solenoid and got incorrect readings that would make me sue a perfectly good ECM. I love having good traction when testing things like taillights. With a long wire I can just turn on and ground the lights. I also like being able to power electrical circuits. It's like checking the fan and starter with a relay circuit. This is a great tool if you use it the right way!
