⚡ Lisle 64970 Parasitic Drain Tester: Detect and Solve Battery Drain Issues with Ease Review

Our 20 year old Jeep suddenly had electrical problems and the battery died overnight. I've tried everything to find the cause and then came across this issue. If you read this review, just skip it and add to cart. You will not regret it. In short, I managed to fix our jeep and now it works great. Do not be shy. For the money you will be glad you bought it even if you only use it once. Much cheaper than keeping the car in the shop and they'll probably use it anyway.

I had a parasitic battery charge that drained the battery overnight. The problem was difficult to understand, but this little gem fitted the bill perfectly. The problem was that the ECM threw open earth on the A/C clutch relay four hours after the car was turned off. After hours of head scratching and guessing, I bought this and watched various ECM driven functions play out. .As the draw rose after the fourth hour, I just pulled the fuses and relays until I found the culprit. Much cheaper than…

My battery died but the alternator charging system was fine leading me to believe there was a parasitic leak in one of my car's subsystems. After you received this product, it came with no instructions and no maps showing where to find instructions online. I visited her main website and she was there, but the instructions were a little vague, especially for those who are new to troubleshooting electrical systems with a multimeter. It would be much better if it came with detailed instructions on

I just wanted to leave a review because I saw some reviews that said it was "wrongly connected" because the switch just shorted the wires. That's what the switch is for. This will prevent current from flowing through your meter when you first plug it in, and the current will surge when everything first wakes up. Leave it for about 30 minutes and then turn on the meter and remove the short circuit (turn off) so that flow begins to flow through the meter without disconnecting and starting again…

I ordered this item in February because I'm a professional automotive technician and I love tools that can make my job a little easier. Well, that was just a headache. I finally got a job where I could use it the other day and it made me chase my dick and end up doing it the old fashioned way. Got a replacement from Revain which was great as I didn't have a return date. Well, the new one has the same problem. I'm not sure how anyone using this tool gets any real results. You should check yours.

I haven't tested this with a 12 volt battery because I'm not sure the instructions are correct. I switched on the 9v battery and tested it with my multimeter following the instructions provided, which means you flip the switch 📴 to use your meter. I couldn't measure any voltage, but I turned on the switch and it read 9 volts. It would be more correct to turn off the switch when you put your cords in the cord holders, then turn on the switch to let the current flow, then read the power…
