Question about Weller D550PK Professional Soldering Gun Kit

1 Answer

Trouble with the 2 work lights

Both bulbs are good. Continually have trouble having them come on and light up the work area. The bulb holder is always loose, and what is
the proper way to keep the bulb mounting in the right position? I can get it to work, but in the next few minutes it wont make contact. I have the
D 550 and case kit. my Weller is used in the electrical trades.
Everything else works fine over the last 15 years.

You need to open the gun case and check the connections to the bulb sockets inside. I have several of these guns and the only problem has been the occasional need to re-tighten the tip screws to break through the oxidized copper adjacent the screws. Good luck!

02 impala back turn singles blink fast, when the hazards are on they blink normal but nothing blinks in the front changed all the bulbs the hazard and turn single switch put new fuses in help

Use a volt meter or trouble light, to test for voltage at the front lights, remove the bulb,turn ignition on, probe from the center of the bulb holder and to the side of the bulb holder must be battery voltage, if not probe from center of bulb holder to metal of car body, if there is now voltage the light has a bad earth, if still no voltage there is fault in the wiring from the lights to the indicator switch, or the indicator switch is at fault.

Hi, i have a 2007 vauxhall vectra. Change side light as dash said not working. Still not working after changing it? Any ideas please. Thx Naomi :-)

Bulbs not working can be for a number of reasons. It could be a bulb, a fuse or a wiring problem. Checking the fuse is easy to do.
Just changing the bulb may not resolve the problem (as in your case). Take the bulb that is not working and place it in another working bulb holder to see if the "so called" blown bulb actually is okay. If it doesn't light up then throw it away, don't put it down as you will get it mixed up with working ones (been there, done that). Take the "known to be working" bulb you removed from the working bulb holder and try that in the "blown bulb" holder. If that doesn't work replace it in the original working bulb holder and see if it still works. If it does then the "blown bulb" holder is the place to start looking. Clean up the contacts on this holder and try a bulb again. Still no luck, check the wiring at the back of the holder for broken connections. Most cars are now wired to light clusters that hold indicators, brake, side, reverse and fog lights. These are all on a circuit board (you will see what looks like silver strips from each bulb holder running to a connector that the wiring loom plugs into). If you have a meter, check to see if you have power to the faulty holder. Sometimes just wiggling the bulb or connector plug will make the bulb work, in which case it is a connection issue. If you can, try swapping over the left and right light clusters (just remove and plug in as they won't fit the car the wrong way round). If the "faulty" cluster works in the "working" side and the "working" has the same original problem in the "faulty" side, then it is the light cluster that has the problem and not the wiring from the connector back into the cars wiring loom.....big relief.
I always find electrical issues frustrating, so be methodical and eliminate any possible problem one at a time. Don't do lots of work and then check because if you can identify the single cause, should it reappear (and it most probably will in my experience) that is the first place to check again.
Good luck and hopefully that eliminates the need to call an expensive repairman.

Having trouble to get brake light to work?

Does the brake light come on when you press pedal? Your question is not very clear, brake light fuse, brake light switch, bulbs, bulb holders, if you explain better you will get a positive answer

2004 ford explorer engine trouble light wiring diagram

The trouble light is in the instrument cluster.behind dash gauges.,BE SURE TO DISCONNECT BATTERY BEFORE REMOVING ANY PART OF DASH..Use safety glasses.,The cluster is attached to the back of gauges..Be VERY CAREFUL If you remove it ..Very Fragile and easy to damage..!!....Older vehicles have a more simple cluster with bulbs that can be replaced or removed..Or leave out and never have a trouble light again..I doubt if your vehicle has a simple bulb however it is possible...If you just wanted the light to go off forever there is a chance you could remove the cluster and it will have a simple small removable bulb..I would ask a Dealer Tech....The cluster is like a map or a weird racetrack..lights for each instrument are located on the pathway...You may could crush the tiny area where light is if it doesn't have a bulb that can be removed but it may interfere with other lights on the cluster pathway or perhaps DISABLE THE COMPLETE CLUSTER..I DONT RECOMMEND CRUSHING ANY PART OF CLUSTER.!!,,However I have seen it done..Some lights are made into the pathway and can't be removed and some are just removable bulbs..Your vehicle could have both type pending on location of your problem light..I have seen many replaceable bulbs located at the bottom of instrument clusters on Heavy Ford Trucks.., however the center lights cant be replaced..Especially if it is all digital..!!..Look for a close up photo of the rear of your instrument cluster on a computer and you will see what I am describing...You may just have a very small plug in bulb..It may be a good idea to ask a Dealership Tech.....Good Luck...

Do you have a scan tool that can access DTC'S - diagnostic trouble code's from the body computer . SJB - smart junction box .That would be the first thing to do . The SJB controls (turns on ) this light's . A problem with the circuit will set a code that should point to the problem area . Doesn't need to be ford dealer ,there are independent repair shops that can diagnose this.

No lights for my license plate. Don't know if it is a fuse or bulb. Where is the fuse?

Typically the license plate light will come on with the running lights....if all the other lights are good I would suspect a bad bulb or trouble at the bulb holder....
Take care.

Right turn light and rear right tail light is out. Replaced with new bulbs and the lights still will not turn on. Please help.

Either you do not have positive 12 volts or the ground at the bulb holder. With a voltmeter or a 12v tester probe between the two connectors in the bulb holder with the bulb out and tail lights on--
If you do not get anything then probe with one lead --red in the bulb holder (switch the red voltmeter lead between the connections in the bulb holder to get a reading)and the other to a good ground --any bare metal part of vehicle.If you get a reading -that means you do not have ground at the bulb holder.
If still nothing--than it means you do not have 12v at the bulb holder. Than try finding a good 12v and work from that a reference point. Confusing? may have to have it checked out
Just in case try a bulb that you know that works..

Rear brake light problem

The tail light housing bulb holders are notorious for not making good contact to the tail light housing. Remove the housing, and disconnect the electrical connector. Label each bulb holder prior to removal, with a marker pen. 1, 2, 3, upper, middle, lower, etc. Remove each bulb holder, by turning counter clockwise 1/2 turn, and withdraw holder. Inspect each contact. You can bend the contacts outward a tiny bit, just flex it a tiny bit, and check with an ohmmeter for contact. Also inspect the bulb holders for melting from bulb heat, so much so that the plastic holder, which contains the bulb contacts, no longer make proper contact to the bulb. Also check the bulbs with an ohmmeter to verify that the bulbs are good. When reinstalling the bulb holders, check that the little flanges on the holders are properly inserted into the tail light housing. Reconnect electrical connector, and reinstall housing into vehicle. On a further note, with the electrical connector disconnected from the housing, you can check for voltages from the connector pins to ground, using a voltmeter. Turn ignition switch to run position, turn on headlight, and turn on blinker, or use stick to push brake pedal, against front of seat, and verify voltage from pins to vehicle frame (or connector ground pin). If no voltage, then check fuses, or broken wiring. My experience, however, is poor connection from bulb holders to tail light housing.
