For example, the radio has a 5 amp fuse. even though this is the max amperage you could use it and be safe. Headlights use a 20 amp fuse. 30 amp for the blower. I would think just go for the largest available and you should be good. I am sure the 100 amp <a href=\"https:\/\/www.freeautomechanic.com\/alternator.html\">alternator <\/a>would be fine but if you also have a hopped up stereo you may want to opt for the 130 amp alternator. Might as well through in an extra large battery as well.<\/p>\n<h3>Alternator Precautions<\/h3>\n<p>To prevent serious damage to the alternator and the rest of the charging system, the following precautions must be observed:<\/p>\n<ul>\n<li>When installing a battery, make sure that the positive cable is connected to the positive terminal and the negative to the negative.<\/li>\n<li>When jump-starting the car with another battery, make sure that like terminals are connected. This also applies when using a battery charger.<\/li>\n<li>Never operate the alternator with the battery disconnected or otherwise on an uncontrolled open circuit. Double-check to ensure that all connections are tight.<\/li>\n<li>Do not short across or ground any alternator or regulator terminals.<\/li>\n<li>Don&#8217;t try to polarize the alternator.<\/li>\n<li>Do not apply full battery voltage to the field (brown) connector.<\/li>\n<li>Always disconnect the negative battery cable before disconnecting the alternator lead.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Selecting an alternator I recently add several electrical components to the engine and chassis.
