Asolutely , capacitors are what we call in the buisness ,starter motors, theese cylinders hold the juice to start the motor in motion ,,do yourself a favor ! don,t buy this part from a garage door supplier because they will get you for 20-30 bucks , Instead go to any good electronics store , and i don,t mean Radio Shack, You want to go to a store that carries electronic parts such as diodes and computer coards and led lights because theese stores also carry capacitors and lots of them , I pay at my local electronics store about 7 bucks and as long as the ratings the same it will worf fine also if the rating is a little higher it also will work , bring your old capacitor with you so they can match it , I go to a place in pompton plains,n.j. called Wayne Electronics they might even be able to ship it to you in the mail if you don,t live around the area , well good luck and i hope i was able to answer your question, Thank you for the oppurtunity to help you , Sincerely Glenn Mayer

My Pioneer MVH-X650BT head unit would start up, connect my phone via bluetooth, aux cable or USB cable and then randomly shut down as if the cord was pulled... as of late, it wont even start up. i us

Sounds like it has a bad capacitor in it, or it could be a short on one of your speakers or wires running to the speakers. A short will cause the unit to get hot and it will shut down to keep it from further damage. Check your Ohms at each speaker and you should have between 2-8 Ohms per line. you also may need to check the connections coming out of the units connectors. Make sure that they are all pressed on tightly and not coming loose or not fully making connections, check all fuses, check all grounds and clean off the area where the ground is maybe moving it to another spot right away.

Can i charge my didgi cap with a batt. charger?? stupid i know but i gotta make sure im stupid before i belive it:)

You aren't stupid just need information about the capacitor!

Here is a short explanation as to how the cap works and also the link:

How the Capacitor Works
  • A capacitor is an electricity storage device; think of it as a short-term battery that can release power quickly to meet peak demands, unlike a battery that releases power in a steady stream. When the capacitor is in-line in the amplifier's electrical system, it will release electrical energy when the amplifier hits a high demand. The power released by the capacitor makes up for the shortfall in the system, so the car's electrical system isn't compromised, and the amplifier has sufficient power to drive the subwoofer effectively.

    It's beeping when turned on. Why?

    I have read that if the polarity is reversed, or the connections are backwards, the Capacitor will beep. If this is not the case, it may need to be replaced.

    How to charge the lanzar 1.6 capacitor

    typically you can charge or discharge large capacitors using a resistor. Not just any resistor will do. You will need one with high-enough resistance and wattage ratings or you'll burn up the resistor. I would use a 1/2W, 4.7kohm or a 1W, 1kohm. These are minimum values and you can use a slightly higher resistance but it will take longer to charge/discharge.

    To charge, connect the positive terminal, then hold the resistor between the ground wire and the ground terminal for 30-60 seconds. Then connect the ground terminal. To discharge, disconnect both terminals, then hold the resistor across the terminals (do not reconnect terminals without charging). In either case, you can use your fingers to hold the resistor as DC will not shock you, but if the resistor gets hot it will burn you. I use needle-nose pliers to hold the resistor (just in case). Just be careful not to short the resistor leads or terminals with the pliers.

    Explanation: For a standard cap 1 - 2 farads, the discharge voltage is up to 20V so we'll figure off of that. I would use at least a 1/2 watt resistor, a 1 watt could be safer, depending on the value. For a 1 watt, the current can be no more than .05A at 20V. For a 1/2 watt, only .025A. Let's say .04A and .02A, respectively. Ohms = Volts / Amps, so 20V / .04A gives us 500ohms. Double that to be safe (avoid overheating) and it's 1kohm. Same process for the 1/2W version will be 2kohm, but it's not as hefty, so I would recommend 4.7kohm.

    35 Farad hybrid power capacitor not charging like instructed in manual, tryed charging the cap throgh the supplyed resistor "2watt/10ohm" between power cable and cap.But nothing happens seems like it dosnt...

    Yes you certainly wire the 12v+ wire directly to the positive post of the stiffening Capacitor, however if you have a one of those test light probes to check for current on a car? They are really cheap but what i do is clamp the one end on to the battery and than touch the probe to the + teriminal of your capacitor, when the light goes out your cap is fully charged. Now if the light does not go all the way out or stays on you have a bad capacitor, and might i ask why the hell are you driving to need a 35 Farad Capacitor anyway?? Damn.. We do show and competition cars here and sometimes use them. I like the BatCap way better, it's a Battery and a Capacitor all in one. Way strong like bull..... good luck... Mark

    Switching Capacitor to another car

    This is a specialized capacitor device. This device is designed to hold and discharge a very high amount of electrical current in a very short time to an audio amplifier as needed during a demand. As with that said, safety is a big issue with any attempt to discharge or transport these devices. That stored current packs a punch if you attempt to dead short it out (not advised, makes huge sparks, could cause damage or injury). You should consult your owners manual concerning your specific equipment. but since you are dealing with only 12-15 volts of electricity, you can just simply easily move it to your new vehicle with no problem, just DO NOT Short it out, or touch the terminals with wet hands when you move and reinstall it. :D

    Sound like the "outfit" that worked on your operator did not change the bottom bushing on your motor mounting plate. Some "outfits" only change the white gear #41A2817 and some change the gear shaft assy. #41C4220A without changing the bottom bushing.

    Chamberlain Power Drive 1/2 HP - motor runs but does not move chain

    I have the same problem. I just removed the cover and discovered a nylon gear had been worn out. I found lots of shavings inside the cover. The nylon gear is beneath the exterior chain gear. I am looking for information on how to replace it, if I can find the part. If you decide to look at yours, unplug the power and remove the sheet metal screws securing the bottom portion of the cener cover to the front and back covers. Then just remove the upper screws from the center cover. Good luck.
