Review: Works great - Great tool to have for the tool box
Review: A Fluke 88 and this Parasite Drain Tester are the perfect combination to find a parasitic draw on a late model vehicle. - A commercially made harness made by Lisle that is so simple but takes the place of the home made 10 watt resister with alligator clips soldered on each end then having to put alligator clips on your test leads then hook it up with one on one side of the resister and the other on the other side, with so many connections made it would fairly easy to miss a current draw of 50 Ma, never mind what the heck is causing it. Disconnect the negative battery terminal, connecting this tester in series to the regular battery cable.This tester is fused, it has an on/off switch, and it has two pass through banana plugs that connect directly into the fused current inputs on your multimeter. This is a necessity for newer cars to detect draws that are so slight that the test light trick will not work here. All of the connections are extremely dependable and the fear of missing the problem due to a bad connection is minimized. Lisle 64970 Parasitic Drain Tester This is one diagnostic tool that I didn't have to think about, as soon as i realized what it was I put it right in my shopping cart.

## Features

- Replaceable in-line fuses protect both the meter and tester in the event a high current source on the vehicle is left on
- The multimeter is bypassed with the switch during connection in case of a power surge
- The tester and meter can remain connected until other computer systems shut down, isolating the drain
- As a convenience, stacking banana connectors are used on the tester
- This allows voltage to be measured on various locations on the vehicle during the drain test, using standard test leads

## Questions & Answers

**Q: How is using this tester preferable to hooking up your multimeter in series with alligator clips and a blade fuse soldered inline with your leads?**
A: It helps because it has inline fuses which will protect your voltage meter. When using your meter directly you risk damaging your meter.

**Q: what gauge are the cables that connect to the battery and terminal. Can I start and run the vehicle with the tester connected?**
A: No, they are a light gauge wire. Too light of wire to handle load of starter.

**Q: Does it come with instructions?**
A: not really, you have to look at a video from mac or matco which has same tool just their name. its hard the first time ,but you can figure it out after you start to use it.

**Q: This seems useless. Why not use a clamp on dc meter?**
A: I liked it because it has a fuseable link on both leads and you can connect your probe to it. I blew a couple fuses while trying to track down a short and it prevented an damage to my rather inexpensive multimeter. It's designed so that clamp it to the battery directly. If you already have leads with clamps then yes this would probably not be helpful to you. It worked great for me fixing a slow drain on our Jeep. I mostly found it helpful while pulling fuses until I found the circuit that was causing the trouble. I could have spent a fortune having it in the shop so I figured spending a couple bucks on this was a much better option.
