hi guys doing today today I'm going to
00:00:02.330 00:00:02.340 show you how to test a capacitor and
00:00:03.949 00:00:03.959 what tools you need to test the
00:00:06.140 00:00:06.150 capacitor okay so what you'll need to
00:00:08.270 00:00:08.280 test the capacitor is a digital
00:00:10.610 00:00:10.620 capacitor mirror you can also get just a
00:00:13.580 00:00:13.590 regular dial meter capacitor meter but I
00:00:16.760 00:00:16.770 like to digital this particular model is
00:00:20.120 00:00:20.130 a new case in xc60 one 3l also to test
00:00:26.089 00:00:26.099 the capacitor the first thing you're
00:00:27.529 00:00:27.539 gonna do is you're gonna go ahead and
00:00:29.390 00:00:29.400 look at the capacitor itself and where
00:00:33.049 00:00:33.059 it says 1,000 UF that's basically micro
00:00:38.000 00:00:38.010 farad this is the negative side always
00:00:42.040 00:00:42.050 wherever you see a black line or a
00:00:45.470 00:00:45.480 circle line it looks like it's a
00:00:47.740 00:00:47.750 negative sign with the white strip
00:00:50.209 00:00:50.219 that's your negative side okay so first
00:00:52.880 00:00:52.890 things first is you're gonna take you're
00:00:57.529 00:00:57.539 gonna take your digital meter I'm gonna
00:00:59.540 00:00:59.550 set it to obviously we got to go above
00:01:02.799 00:01:02.809 1000 UF or micro farad because that's
00:01:05.960 00:01:05.970 what the capacitor calls for so we're
00:01:09.890 00:01:09.900 gonna go to 2000 UF and that's where
00:01:15.530 00:01:15.540 we're gonna start testing the capacitors
00:01:17.480 00:01:17.490 at you always want to go higher than
00:01:19.999 00:01:20.009 what the capacitor says because it won't
00:01:22.670 00:01:22.680 read okay so like I said the negative
00:01:26.630 00:01:26.640 side is right here so we're gonna go
00:01:28.880 00:01:28.890 ahead and keep it on the camera I'm
00:01:33.230 00:01:33.240 gonna put the negative there and the
00:01:35.960 00:01:35.970 positive there and we're gonna do a
00:01:37.219 00:01:37.229 reading real quick
00:01:38.270 00:01:38.280 now this one's rated for 1000 you
00:01:40.280 00:01:40.290 usually want to go with 10% so this one
00:01:44.810 00:01:44.820 obviously is a bad capacitor 866 10% of
00:01:50.690 00:01:50.700 a thousand is 900 so you don't want to
00:01:53.149 00:01:53.159 go any lower than 9 heart so 866 that
00:01:55.730 00:01:55.740 that capacitor is on its way out so we
00:01:57.920 00:01:57.930 have another capacitor here it's also
00:01:59.240 00:01:59.250 rated 1000 UF you don't have to worry
00:02:02.780 00:02:02.790 about the voltage this one says 35 volts
00:02:05.510 00:02:05.520 don't worry about that
00:02:07.830 00:02:07.840 if you're changing a capacitor out you
00:02:10.479 00:02:10.489 want to either stick with the same
00:02:11.949 00:02:11.959 amount of voltage and the same amount of
00:02:14.170 00:02:14.180 UF or higher you can go higher you can
00:02:17.619 00:02:17.629 get a I'd say if it's a 35 you can get a
00:02:20.410 00:02:20.420 40 50 60 volt capacitor that just is the
00:02:24.490 00:02:24.500 rating of how much abuse it can take
00:02:27.100 00:02:27.110 before it pops but you do not want to
00:02:29.920 00:02:29.930 change the UF or the micro farad you
00:02:32.380 00:02:32.390 want to stick with the same number okay
00:02:35.170 00:02:35.180 so we're gonna test this one
00:02:36.460 00:02:36.470 another negative negative and positive
00:02:39.369 00:02:39.379 on the positive and as you can see this
00:02:46.839 00:02:46.849 one's 895 give or take it's off by 5 so
00:02:55.330 00:02:55.340 it's probably like 10.2% bad you could
00:03:00.940 00:03:00.950 probably get away with this one
00:03:03.059 00:03:03.069 so that one will roll out okay now
00:03:07.059 00:03:07.069 here's another type capacitor it's a 25
00:03:10.000 00:03:10.010 volt thousand UF so we're going to put
00:03:13.240 00:03:13.250 it on the negative and the positive and
00:03:21.190 00:03:21.200 this one is rated at 9:38 so that's a
00:03:24.220 00:03:24.230 good capacitor so pretty much you're
00:03:27.610 00:03:27.620 seeing how I'm doing all this gives you
00:03:30.220 00:03:30.230 a good idea I'll here's a little
00:03:31.660 00:03:31.670 different one this one is a 16 volt 16
00:03:35.140 00:03:35.150 volt capacitor at 470 UF so let's go
00:03:40.360 00:03:40.370 ahead test this one and we're good for
00:03:51.099 00:03:51.109 thirty-one that's a good reading less
00:03:54.190 00:03:54.200 than 10% okay so I showed you how to
00:03:56.620 00:03:56.630 test capacitors if you guys have any
00:04:00.190 00:04:00.200 questions please feel free to leave text
00:04:03.670 00:04:03.680 or message me but hope you enjoyed my
00:04:06.430 00:04:06.440 little video and please subscribe
