OK, I keep reading that you must take out capacitors before checking and then I read something else.....Who can tell me the truth about this? If I can't test them in line, why would I waist money on a meter?

The good ESR meters like the CapAnalyzer88A discharge the electrolytics before testing to prevent damage to the meter from a charged capacitor.

The LeakSeeker 82B locates the exact spot on the pc board (to within a quarter of an inch) where a shorted or leaky component is bringing a power supply bus or data line to ground. It is the only locator that can locate defects from zero to 150 ohms with no loss of resolution. It can even find active shorts that a DVM won't even show. Now shipping the LeakSeeker HD , which has a High Definition mode that can locate shorted components on multi-layer boards with ground planes and a power layer. Amazing! 60-day satisfaction or money-back guaranty.
I've tested caps with my DMM and an ESR only to find the cap to be bad regardless....but that is a very small amount to pass both testers and still fail.
