        Q: How come my truck won't start?; new battery and new distributor/cap?
A: It is perhaps not the battery , but try this :   It takes roughly 9.5 volts began to a automobile . If you hear a click sound , your battery 're not putting out sufficient voltage . Your radio , headlamps , etc. , will all work , so you 's going to think that your problem 's your starter . NOT SO . Either you have a weak battery which need charging , or the looked just likely culprit are your battery cables . Most people will look at their cables and if they LOOK clean , and do n't see any white corrosion building up on the terminals , they thought the battery terminals are making a good contact . Once again - NOT SO . Those terminals and cables are lead . Lead is a shiny metal . Scrap the top of a battery terminal and it will shine . That darkness on the terminal you scraped off 's also present between you battery terminal and cable , and will prevent a good contact . All it was necessary is to cause a decline in voltage to your starter and you will hear a clicking sound from the beginninger .  Get a good battery terminal and cable cleaner at your automobile parts store . The type with the wired inside that will truly make those terminals and cables shine . Once you have sanitized them , your battery will put out max voltage . If you still hear the click sound , take your battery to an automobile parts store and they will verify it . It is perhaps not holding a charging or you are able have a deceased cell . However , DO NOT try and clean your battery terminals with Baking Soda or Coca Cola . I 've cooperated in automobiles for over 50-five years ofs and everything that does is clean the OUTSIDE of the wordinals - NOT the link between the cable and terminal .  So numerous people run out and buy a new beginninger or battery when it is really the link himself . 

Q: Correct hook up for car audio capacitor?
A: I made the error of not using a capacitor on my system and I have shall be substituted for the alternator and battery each year . You wo n't need another fuse between the cap and the amp , but you do required to use another ring terminal . If you ever wish to broaden your system and add another amplifier , you will be happy you got another ring terminal . No matter wherever you live , there exist custom automobile audio places nearby and they have tons of them . Just ask !
