It normally says on the case of the radio where the plug inserts. If not, get a DC Voltmeter and carefully read the voltage and observe the polarity of your test. Most radios have a positive tip polarity. Good Luck

How do i find lighter fuse


Lighter fuse for corolla is on the interior fuse panel on LHS of dash. It is labeled CIG. And is a 15amp fuse, this is common for them to blow when people plug in charging devices or sat. Radios into them, try using the power point socket in centre arm rest.

Hi,i'm having trouble with the cig lighter on my car, it keeps blowing fuses. can i wire it directly to the battery with an inline fuse? How would i do this?


you could do this by running 2 wires directly from the battery to the back of the cig lighter and by fusing the positive.if it is only when using the cig lighter and not when charging a phone ect.it could be element on the cig lighter shorting

CIGAR LIGHTER WILL NOT CHARGE UNLESS ENGINE


Some cig lighter plugins are wired directly to battery, others are connected to ignition. You can always re-wire it straight to fuse or radio memory wire (Yellow) on cd deck or (Green/Black) from car wiring

Looking for the cigarette lighter fuse


Check all fused related to audio, dome light or instrument cluster. Try plugging a cellphone charger into the socket for cig lighter, if this works then you need a new cig lighter.

The cig lighter is probably part of the circuit tied to radio instrument cluster or dome lights, if any of those are out too, then it is likely a bad fuse or bad ground. Look for corresponding fuse and kill 2 birds with one stone hopefully by replacing the faulty fuse.

If you locate and replace a faulty fuse and the problem persists, you may have a bad ground. This is a bit more involved. I would guess by your question that you will need to have someone service it for you.

Fan blew 12v car fuse


You probably burnrd out the wiring into the lighter or, you burned the contacts in the lighter socket. You can not use an AC fan in a car. A car is DC.

Radio and cigarette lighter won't work 1996 Ford Ranger


Read your manual .It tells you were the fuses are.. If you use a test light,the terminal at the bottom of the lighter socket is positive and the barrel is ground.Don,t touch the two,or you will need another fuse. The fuse panel is on the left end of the dash.The cigar is #17 and radio is # 20

1991 s10 pickup radio and cig. lighter shrts out


You need to replace the lighter socket. Both of my 1988 S10's had the same problem after a few years of using my cell phone battery charger in the lighter plug. I replaced it 10 years ago and it has been fine ever since. Something in the original socket wears out and causes it to short out when something is plugged in. Good luck!
