SOURCE: blinking tem light on optima

Its likely to be one of the fans at the front of the projector thats running slow or not at all. I had to take mine out and soak in WD40 dry and replace - all works now. The light will come on even if the projector is cool if it detects a slow running fan.

Led turn signal

mods, it's a modifcations post. rare... here...
first off ,you did willingly break your car, why do that.?

and if car has issues later on the road, the mechanic will hate you for this.
he may in fact say, sorry buddy, take it to a custom shop....
(it is your car, but...... think about the future... and resale, id never
buy your hacked up car. me and millions like me.... )

but if so inclined, you take the factory drawings (FSM)
then red ink the mods.
then post it and i can answer with 100 % accuracy,

your lights on off post makes no senses
my guess is the park circuits are crosswired.

one big failing with LED modders. is the lack of understanging
that some components on the car are sensitive to current'.
or have normal leakages. bad for LEDs.

that would just hate LEDs.
and the one in this car is not SPECIFIED.
how many LEDs did you install and where, we got the turns stated.
are you LEDing the Park circuit too ? aka TAIL?
the hazard module in the column, is an electronic type module.
the jeep lights are oddly wired,
see the schematic below. see how the
1 lamp element us used for many functions?
ignore red balls, they are for brake failure only.
http://www.fixkick.com/look/odds-ends/jeep/95wrang.jpg

the blk-yell is the park feed. if the park switch leaks, the LED will glow easy. . keep in mind the switches being old and the grease starts to conduct (metal wear ) and at 0.010 amps the LED glows.
so fails. a 1 amp factory lamp draws 100 times more, so will no glow.
see? the only solution to that is a new combo or removing all the nasty old grease in the switch. (im a certified tech, retired and see it all)

now look at the tan wire. ( the brake/ turns are shared , on jeeps)
see the TAN?
see how the markers are wired to brake turns? feed>?
odd , huh?
for sure the LED usage will in fact find all current leakages in the whole circuit. just 10/1000th of an ampere and it glows,
i hope this helps, but do post the mods to my drawing.
and we can in fact find any failure. any leakage,
sure can. with and accurate drawing and a meter.
good luck.

Camera will not turn on when i try charging is one red flash

You can not power the camera while plugged into a usb port on a computer, only using a wall plug or car lighter. Also when you insert a battery into a hero3 or 3+ black model you must wait 4 seconds before trying to turn it on or it wont turn on until you remove the battery and then reinsert it while waiting 4 seconds to try and power it up:

DOES THIS DIMMER WORK WITH LED LIGHT BULB

It's not quite that simple..

According to the manual for your switch, it is stated "Use with magnetic low-voltage transformers, incandescent, or 120V halogen fixtures only." Also, there is a minimum load of 40W or 40VA. Your LED lamp load will need to satisfy BOTH of these requirements. Electronic circuits are not to be "dimmed" with this dimmer - but use of either the VZE04-1L (400W max) or VZE06-1L (600W max) is supported.

You will need to provide the manufacturer and model number of the LED lamp(s) to be dimmed by this switch. Or, you can use traditional dimmers (if desired) with LED lamps that are specifically labeled as "dimmable" on their packaging.

Once the lamp model is known it will be possible to learn about their dimability assuming that they are not cheap imports with no real customer support contacts. Name brand lamps will have this support, and you can even call them yourself and inquire directly about the suitability to task for the dimmer. If the lam company doesn't know about the switch, contact Leviton with the lamp info at Customer Service: 1-800-323-8920 • FAX: 1-800-832-9538 Tech Line: 1-800-824-3005

Good luck!

Hi Ajin, I have a LG RD-JT52 Projector which I

HI David,
Sorry for the late replay first of all. I dont have the service manual with me. So i need the service manual for assist you. One more thing is You will not be able to connect the led directly to the power supply of your projector. For that you need Buck converter to connect in between the led and power supply. Normally leds are of voltage between 1.8V to 3V range. That will be mentioned in the PDF datasheet of the LED. The tearm BUCK means to reduce the voltage From the applied voltage to the range of LED working voltage. If not the led will burn out. You didnt mentioned about is the buck converter is there or not . If its there i want to know the input voltage range of the Buck converter. If it is not there, sent the service manual i will check out and tell you what type of buck converter you need. And how to replace with the LED if it possible. My email address is [email protected]
