Review on 🚗 allsun Automotive Electrical Circuit Tester Power Probe: A Comprehensive Diagnostic Tool for Auto Electrical System Diagnosis by Joseph Hill

Our 20 year old Jeep had a parasitic traction problem due to a bad ground wire. It seems strange to me, but that's all. And I tried my best to find the cause of the problem but to no avail. I was looking for a diagnostic tool and came across this one. I'm so glad I bought it. Instead of spending lots of money at the store to have them track down the problem, I was able to do it myself. I pulled the fuses until I saw the current drop on the multimeter, then used the schematic to figure out what wire color to look for. In a few hours I solved the problem and the battery no longer discharges. I especially like that this sensor shows red or green for positive and negative, no need to constantly fiddle with the battery. I connected it to the negative pole and it gives readings for both polarities. Very convenient. Gets the job done quickly, no fiddling around trying to figure out if the current is going the wrong way. I've only used it once so far, but I'm sure it's paid for itself a hundredfold. Feel free to add this to your cart.
