Question about BOSS AUDIO CAP3-5B 3.5 FARAD CAPACITOR, DIGITAL VOLTAGE

2 Answers

For some reason my capacitor wont charge, I've checked everything! I just bought a boss cap3.5b and I know for sure the fuse is working there is power coming from the battery and the cap is grounded correctly. But for some reason when I connect the resistor to the cable and to the cap nothing happens! The voltage meeter doesn't turn on at all and also doesn't flicker. What's wrong?

Get a small led or something that runs on 12 volts. i use my 5 dollar 12v test light and hold it to the positive cable thats gonna be hooked to my cap.
hook the other side to the cap, it will light up the test light and in a minute or two the light dims and then goes out, after its out , the cap is charged......JUST DONT LET IT TOUCH THE OPPOSITE WIRE WHEN YOU HOOK IT UP OR YOU DISCHARGE IT and its not funny

SOURCE: 35 Farad hybrid power capacitor not charging

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

No vertical everything else is ok


Check and replace all the electrolytic capacitors {5 or 6 of it} at its vertical scan output section circuit. Replace all at one time. be sure about the polarity of these capacitors when replace it. As you know, all electrolytic capacitors have both +Ve and - Ve terminals, must coincide with to that the marking at the PCB.

Laptop was not charging so i bought a new battery, still didn`t charge so i bought a new charger, but it still will not charge or turn on. any suggestions


The capacitor in the mother board or a fuse is blown
It must be opened up to check
Usually a qualified technician must do this for everything inside is so delicate to remove

My cruise control doesnt work


First check the brake switch if it is sending a signal that the brake is applied the cruse cont. wont work. If the vehicle is a standard then also check the switch on that pedal for the same reason. I don't really know what you mean by "the gas light" do you mean the light behind the gauge or?
