a little advice on my front turn signals

[mar67655]

i bought led turn signals when installed them it keeps popping the fuse i know the wires are matched correct when i plug in the stockers and replace fuse works perfect what am i doing wrong

maybe try a new led relay Triton e35 I think.

A relay won't keep the fuse from popping - maybe a bad connection within the turn signal - use a multimeter to check for shorts.

LED = Light Emitting Diode. It will only allow current to pass in one direction. If you wire them up back words, they will block current and pop a fuse (and not light up). Check your wiring to make sure you didn't wire them wrong or possibly cause a sort somewhere. If you lucky, you didn't blow the LED bulbs.

switch the wire and try again. The colors are different on aftermarket leds.

I would unplug one at a time and try to narrow down the problem leg. You may have a slight short in a blinker unit. You could try testing continuity in the questionable blinker. If you do have continuity, there's your problem.

You are 2/3 correct. Yes a diode will only allow current to pass in one direction and yes if you hook it up backwards it can blow the LED. HOWEVER - if the diode is hooked up backwards, since it BLOCKS current, there will be no current flow and therefor the fuse cannot blow. If the LED does blow 99% of the time, it will blow open - and once again no current.

@mar - please do actually troubleshooting by trying to find the short using a multimeter - replacing fuses just to see if they pop after unplug/replug things is not the best way of doing things. Not to mention bad for the wiring (especially if you decide to replace the original fuse with a bigger one.)

thank you for your advice

Correct, but not really lol. You mention 90% of the time. There fore I would be correct if it happened at all (10% of the time). I build avionics for UAV's (unmanned Air Vehicles AKA: Drones) and been doing it for just shy of 2 decades. Murphy is a funny guy, and I've spent hours chasing down problems because a diode and / or capacitors blew and shorted, where you are always taught they blow open. I've also had resistors go bad and turn into shorts (what are the odds of that!). My advice was a generic way to quickly trouble shoot 4 wires and assume NOTHING because it's so easy to trouble shoot. Thanks for correcting me however

I hope I didn't offend - but "If you wire them up back words, they will block current and pop a fuse" is totally false and is the only part I really have a problem with. Other than that it's cool.

Off topic: Are you in the service? I did the avionics on Apaches for a few years, along with a few Blackhawks - I'm not doing more schooling as an instrumentation tech for power stations. [cool]

No offense at all!, I just re-read what I wrote, then what you wrote and brain farted. I wrote it out of order, thinking if the LED blew and closed the circuit he'd have a short, your correct.

Not in the service, a few people in my company past and present were though. We are a private company (Microbotics, Inc.). We had a Crata agreement with NASA Langley and had our base set up there for a decade, but moved out due to politics. We weren't contractors, we weren't NASA employees, we just had free space in exchange for whatever technology we felt like sharing, but they tried to impose a lot of their rules so we bailed out and moved across the street to our private building lol.

Buells, planes, guns, cars, and quads [cool]

send them back and get new ones.you have at least one bad one maybe both.

 

[BuellerPilot]

Ohh, and RC stuff too!
