Test bulb how to test the bulb in model f20t12

Hello Deryl Priest,

The quickest & easiest answer is to get a couple
more lights ... and try again.
(we could help with Make & MODEL numbers).

Most USA market bulbs are "Edison" e26 appliance
bulbs... sold SPECIFICALLY as appliance lights.

Any one of ordinary lamp sockets can be used to
check ALL those bulbs (old & new).

ELSE...
Any novice with a VOLT-OHM Meter... can test
your bulbs for "continuity"...

Please COMMENT back for assistance testing.

If you still have the OLD BULBS (you removed)
it might be a good idea to try to test them...

Your problem might be a DOOR SWITCH instead
of a bunch of Bad BULBS...

Get your model number... and come on back..
or look up the USA (domestic) part houses

Normally the light bulb function should not affect the machine's ability to operate, however, it could be if your machine is a computerized model. Try replacing the bulb and then test.
...

1st try a different bulb, make sure its a working bulb, If the test light is blinking & u have a good ground it has to be the connection from the bulb to socket.

What year and model is your subaru ?

Is it a singe ground issue? Fuse? ?????????? Without doing some testing we would be just guessing. You need to test the electrical circuit to know for sure . Voltage drop testing !

Under system click on lighting ,then under subsystem click head lamps . Click the search button then the blue links. Look at the wiring diagram to see what all is involved in making the head lamps work .

Voltage drop test the electrical circuit .

Mastering Voltage Drop Testing with Pete Meier and Jerry Truglia
Do you know what a wiring diagram is ? Do use a test light ,use a DMM - digital multi-meter . Free wiring diagram here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model . Under system click on lighting then under subsystem click on turn signal lamps . Then click the search button then the blue link . Scroll down to last diagram .

Please check using a tester/multimeter for the voltage on the bulb holder or test if the bulb within is fused or not using a continuity test. If not the fault can be with the main door switch of the fridge - normally some switches fail and so there will be no contact. If not there can be break in the circuit line/wiring to the holder.

Check for the Bulb as they have two wire on it,maybe one for the turn signal is out....Remove it, and test the Bulb with a test lamp and Battery......

Don't know your Lincoln model, but replacing the headlight bulb can be OK...inpect the underhood location of the Headlight assembly...review the back side, which holds in the bulb...you can check your local parts store for exactly which bulb your model needs...be sure to use gloves when handling the new bulb...the natural oil on our fingers will cause the new bulb to wear out prematurely...Most headlight assemblies are fully removal from the car allowing you to switch out the bulb from the backside...reassemble, and be sure to test before final assembly...Bulbs will range from $8. to over $50...depending on design and preferred performance...Hope this helps.

Test the connections on the bulb for continuity using a test meter.

Google

make model television manual

to see if the are reset instructions after replacing the bulb module.
