Put the test light on the wire on the starter, you should have 2 wires-the big one.
Try to start the car. In a normal situation that wire has power to it when you turn the key to start.

2007 Mini Cooper convertible, stereo signal got worse and now can't listen to the radio, other functions still work. Have changed aerial and still no change? Any clues??


some sort of bad connection inside the radios socket
or bad coax

check the antenna with an ohm meter
to see if the coax is shorted out
and also that there is continutity between the center pin of the coax radio plug and the antenna

you can demount the radio and stick a bit of wire in as a quick test
if you get the signal then its something coax related
if not its something to do with the front end of the radios reciever circuit
and you need a radio engineer that fixes car radios and cb etc
they will make it work for sure
i could in ten mins flat ...possibly a transistor has failed
or a bad connection as it comes and goes ...

'94crown Vic radio stopped working. Checked fuse under drivers side, checked the ground wire, and those are good. All the lights on the radio come on and everything seems to be lit up, but there is no...


are all the radio function dead.?????
what are they, radio, AM and FM dead, cassette, CD,?
if only the radio is dead. (static) then the antenna is bad or its lead in coax wire is bad. or fell off. etc.
the amp (audio is good) as you heard the static.
you can unplug the antenna, wire, from radio and plug in any
lenght of wire to test the radio, any radio can be bench tested this way. and is in any shop.

its very rare today for any head end radio unit to be only a radio.
so do the other features (other audio sources work?) try them.
if they work then the antenna is bad.

Dash lights arent working on a 99 explorer, fuses are fine and all the other lights work. quit working after installation of aftermarket stereo


OK, that radio use a straight or constant 12 volts a ignition 12 volts and grounds. now your radio ground might be connected to the park light wires of the car. that wire will should grounds ( - ) but when you turn on the park light it turns to 12 volts to illuminate the dashboard gear shift etc. if that is the case you're wondering where you will get grounds to collect the radio, well the antenna wire has ground, so plug and play, and the frame where the radio goes has metal, which is also grounds. disconnect the black wire from the radio and that wire you can test by turning the park lights on and you will get 12 volts

I was having this problem with the Honda radio and I have since replaced it with an after market one. I still have the problem with needing to disconnect the battery for the radio to work for a little...


a new radio?, or used, make and model # , must i guess?
all modes on the radio dead, AM/FM,CD/USB/IPOD jack
ALL, that be the first tests and if all bad that means you lost power.
does the radio scan? show signs its trying? when asked, LCD live? or dead. all i know is the word PROBLEM (vast possible)
did you ask the maker of said radio.
did you follow the new radio's instructions sheet.?

disconnecting the battery, wow !

the radios can have 3 or 4 power pins.
1: Radio power (head end power)
2: dial light (goes to car park dimmer)
3: some have a memory wire, if not connected all programming will be lost. this must go to HOT ALL TIMES line.
4: electric antenna, (it's an output but is power)]

and at least 1 good speaker connected.
and for AM/FM any test antenna or just a wire 12ft long works.
the radio can be bench tests.
1 battery 12v
1 radio
1 speak or 2.
1 antenna. now can test for days like this..... anyone.

My dome light and radio do not work. on my 2001 Ford Escape


It almost sounds like an interuption in the security system. Have the vehicle tested by a dealer or qualified mechanic.

All radio, cd tape function buttons on 98 explorer stopped working


just removing ur radio would cause this (ive had mine out a dozen times) make sure all plugs and the antenna is plugged in snug, also you can try another compatible radio just to make sure from another ford (the two square connector style is refered to as the "world" plug)

GAGES GOES HAY WIRE WHEN DRIVING. MY RADIO TURNS ITSELF OFF AND ON. DASH BOARD LIGHT FLICKER ON AND OFF. LIGHTS ARE DIM AT TIMES. DOES NOT WANT TO START ONCE VEHCILE IS NOT RUNNING. HAD IT TESTED, IS NOT...


This sounds like the X-files "electrical gremlin" that these vans are infamous for. I'd start with the wiring harness connector pins on the back of the instrument cluster. Earlier versions of this van have had copious problems traced back to this issue. Just re-solder the pins on the circuit board (my 98 Voyager has 13 of them) and this may solve the problem. If not, then there is likely some other electrical connection issue somewhere along the wiring harness. Others have traced the problem to the connectors on the heater and A/C controls on the middle dash panel. I suspect similar problems on my own van are likely located in the block connectors under the dash, or possibly old/worn/brittle wires somewhere in the engine compartment. Just spend a few hours tracing wires from your dash and making sure all connections are tested, secure, and functioning. This can be time consuming, but it might be the only way to avoid excessive/prohibitive mechanic rates! (I'll be diving into my own van's wiring tonight - while the weather is still warm)

Radio effected by brakes?


If this happens when the car is still you have voltage interference between brake light voltage & antenna. If this happens from motion check all wire connections, loose antenna wire, to antenna.

Instrument panel dials all pegged to zero or max


ok let me help you get started
this isnt going to be easy we need to do a bunch of testing.
you will need a 12 volt test light.
remove the negitive battery cable and connect one side of your test light to the battery negitive and the other side to the battery cable . and with the key off.. so now if you have a short some where the light should be lit. now what we have to do is start to pull fuses untill the light goes out. and when you find the fuse that is causing your short and drain your battery . then we have to look into the section of the wiring and components.
let me know what you find
later paul

AFTERMARKET REPLACEMENT FOR AUTO ANTENNA


sounds simple
placement of antenna is important this will determine which wires to use
most antenas are in the trunk of vehicle with a wire clip to connect or disconnect
tools needed
test light
find your wire clip running from old antena this will be where test light will be used one side of clip is full powered the other is key powered find good ground tip the test light on first prong light stays on this is full power other will be key powered

now your looking for the simple color wires ok on the back of your sterio there is an atenna wire which is blue this will power on only when sterio is on the other wire
you use test light to find without key in take your test light and find a permannent powered full on wire hot supply then connect antenna into these 2 things

at top the reason i mentioned this is cause the old power antena you can find the right leads in the trunk area where new antenna going to be placed with the test light you might need a second person to help you testing wires you in the back and them in the front turning the key on when you need it it makes things simpler with 2 people
i hope this helped you in your quest for knowledge
