Finding Parasitic Drain
Hi all:
I'm trying to chase down parasitic drains on my '01S 986 and my '87 951. The procedure as I understand it is:
Here's the issue I'm facing. When I try the procedure on either car, I never see any current. This is true even if I turn on one of the systems like the parking lights. Anyone have any suggestions as to what I might be doing wrong? If I can measure a current even, then I won't be able to chase down the drain. Thanks |

Thanks particlewave.
Well, I tried your suggestion and still no joy either on the 986 or the 951. When I disconnect the jumper cable, everything seems to go dead. I'll check the multi-meter once again to make sure its capable of reading DC current and I have the probes inserted correctly. I'm pretty sure I do. |
Yeah, sounds like no continuity through the meter. Either bad probe/wire, connection, setting wrong or the meter may have a blown fuse (meters usually have a fuse or two for the current setting).

There is a guide to what the battery drains should be (after all, those remotes must work, right) even a chart of how the drains change over time and how to check them here. Ignore the list of batteries, it is somewhat outdated. But the basic testing techniques are the still the same.

Hi all:
FYI: George from 944 Ecology sent this link. This procedure seems much simpler / easier than the one I suggested. https://www.youtube.com/watch?v=lRcj1fQcWwU |
I always wondered if a clamp on DC ammeter is sensitive enough to help with this kind of troubleshooting.
