Question: I simply put a new bulb in on the back right, and the following day it was failing. I took it out to look, and also it looked nearly burned or melted on the bottom wherein it connects within the socket. What go this mean?

Answer: There might be part resistance in ~ that component of the circuit. Check the connections at the earlier of the socket. The wire must be well connected. Also, examine the ground. Too much resistance will reason the socket and also lamp come overheat.

Question: Both my indications keep flashing and also I can't revolve them off. What might be the problem?

Answer: There might be a brief circuit. A power wire in the rotate signal circuit is more than likely in route with the risk light circuit. You'll should test the circuit. A test light or voltmeter and, probably the wiring diagram for your version can assist you here. Expect this helps.

Question: I have a 2014 model, 3.2 4x4 Ford Ranger. The front and rear, best turn signal don’t work yet the irradiate indicator ~ above the dashboard work. Any kind of advice?

Answer: There can be a trouble with the turn signal switch or a faulty connection. Use the repair manual for your version to locate, gain accessibility to the switch and connectors, if necessary. If friend don't have actually the manual, inspect the referral section the your regional public library. They may have actually a copy for your details model.


Question: every my left-hand side indicators and also hazard warning work; however, the best side doesn't. Would breakdown assist and also would it be covered, as it's unsafe to drive home? and as far as I deserve to make out it’s not the bulbs or fuses in the car. Although i haven't checked fuses or relays in the engine. Also, the next repeater in the driver's door, i m sorry is a addressed unit, that bulb is blown, would it take the entirety right next out?

Answer: Usually, this is due to a faulty turn signal switch. But you could want to check the bulbs first, and also any potential faulty indications you might see in the sockets or wiring to them. Shot swapping the door irradiate bulb with the the opposite one and see what it does. You can additionally test the switch using a test light. Walk over ar two in the post.

Without the wiring diagram, it's hard to tell.

Usually, the flasher relay and also signal switch are the most typical sources of trouble for this kind of problem.

But you might want to dual check how you wired your brand-new LED lights. It relies on whether you're using double beam (one bulb) or single beam (two bulbs).


Probably a chat through these guys could be more productive.

here’s a weird one...

I have actually a 1974 volvo 142. As soon as I tested revolve signals, I obtained inconsistent results and suspected I had a loose bulb, connection or fuse issue.

I know nothing of the vault owner various other than over there were components in the tribe that says they to be resto modding and lost interest.

I pulled, cleaned and also replaced every fuses. Ns unplugged all switch “hubs” or “step down connectors” or whatever they are dubbed (located in engine bay) and also wire brushed corrosion and reconnected (possible suggest of mistake).

I put in all brand-new bulbs and also checked voltage to each socket (there is voltage, couldn’t tell girlfriend if correct amount)

I turned ignition without crank to strength the lights...

when i signal left or right, I acquire Hazards! (?)


The just thing I deserve to think of as soon as considering what go wrong:

1: I connected the multi pen Hella step down dimmer/high beam incorrectly. However the diagrams are daunting to find and also I don’t even know if the hazards/turn signals room even associated with this part.

2: once I eliminated the voltage regulator and put earlier on, I had actually two grounds: one indigenous the alternator, and another from the ideal head light. Ns attached the grounds to each of 2 mounting screws for the voltage regulator (maybe that’s okay?)

Second issue:

I replaced my OE headlights with sophisticated LED.

headlights are activated through pulling a knob. A fifty percent pull transforms on every signal lights (just on, no flashing) yet no headlights. A complete pull to add the headlights.

1: I‘m pretty sure i readjust from short beam to high beam by either a half to full pull of the knob OR by pulling back on the signal lever. However, ns can’t it seems to be ~ to move to either. The lamp beams are just “On”.

Could both of these issues be related to the action down switch an installed on the finder well? wired incorrectly?


Nicole - you could want to examine the voltage drop because that the charging system as well. The test makes sure the connections are good, no corrosion, loosened or damaged wires, etc.:

Dan Ferrell (author) ~ above June 17, 2020:

Try this: turn the ignition crucial to the top top position however don't begin the engine. Have the right to you view the battery irradiate come on, ~ above the dashboard. This is to examine the exciter wire for her alternator. If this wire is damaged, your good alternator won't fee the battery. If your model has actually this wire coming off the battery light pear on the dashboard, the battery irradiate won't which if the is broken. However your specific model may have this cable hooked to the voltage regulator through a fusible link. If the fusible attach is blown, same results, your alternator won't fee the battery. So you may be running your automobile with battery power without letting the alternator charge or properly charge the battery. Examine the location of this wire in your certain model and test because that voltage. You may need the diagram because that your details model. Expect this helps.

To add to my last post about 1999 Ford Windstar, every time we jump it every little thing works fine no difficulties or noises or anything, simply when we shut it turn off the battery soon drains and blinkers walk crazy.

Nicole top top June 17, 2020:

I have a 1999 Ford Windstar. Only 120,000 mile on it, to buy it in ~ 115,000 and also never had difficulties with it till recently. Once we closeup of the door the automobile off the blinkers would certainly blink on and sometimes opened a door cause this together well. Than when we shot to revolve the vehicle on it would certainly not start. This occurred for around 3 days and also then as soon as AutoZone tested the battery stated it to be fine 보다 tested the alternator i beg your pardon failed, so immediately we adjusted the alternator. 5 days walk by and also it beginning doing that again. Test alternator and also it's fine, check the battery and it's fine yet a man said could be battery due to the fact that it's almost 3 years old. We have nothing charging nothing plugged in and also today after transforming it turn off my father tried to rotate it back on and also nothing, however blinkers flashing and also lights came on, and also my dad claimed the theft irradiate is randomly turn off which is a new thing.

I am not a car person but I know electrical energy electronics and the whole blinkers flashing the minute we revolve off the car and also battery draining means to rapid now makes me think some kind of cable brief or some brief circuit. Probably it is the battery but if the car is totally off and the alternator is fine ns dont see just how the battery might just drainpipe that horribly in ~ seconds particularly if it passes the test at AutoZone and a secondary mechanic place.

Any principles on what's wrong? I read stuff around corrosion sockets, cables, move assembly, my father carried up ignition switch and I want to recognize what others might think

Hi Dan, I have actually a 2006 Chevy Colorado. Both the front and ago left side rotate signals blink common on the exterior of the truck and also the left arrow on the inside dash instrument cluster blinks normal as soon as putting the move in the left position. As soon as the revolve signal move is in the neutral position both the rear left exterior turn signal bulb and the dash tool cluster arrow stays lit heavy (not blinking) and drains the battery. If I placed the move selector in the right position the external front pear blinks normal and the rear ideal does no blink at all and also the left arrow on the within dash tool cluster continues to be lit solidly(the right arrowhead never comes on), When turning on the flasher it is the same definition both the outside front and rear left bulbs and the ideal front blink normal and the rear right doesn't work and the within dash left arrowhead stays lit solidly. The ground appears to be an excellent in the rear ideal bulb since the same bulb is provided for the tail light and also works. I switched the bulb with the left side and also it works on the side so that is not the filament. The dark green turn signal power supply cable doesn't seem to have power coming into the connector as soon as I checked with a check light. Execute you have any kind of idea what would cause this since I can't follow the wire diagrams as well well? go the 2006 chevy colorado have a flasher? Looks favor the switch notifies a bcm.

A week ago I bought a revived 65 Pontiac GTO. Now I discovered that the rear rotate signals and brake lights perform not owrk. The prior signals room fine. I replaced the bulbs, also though they looked good, and also the sockets. With the bulbs removed, rotate signal lever in left turn position and also the test light base to chassis the left socket flashes and also the right socket has steady illumination. As soon as the bar is in best turn position the test light flicker in the appropriate socket and also glows in the left. With key on and turn signal lever in the center the ideal rear irradiate is on. Over there is likewise a scenario, though ns forget exactly when, that the appropriate signal flashes v the bar in the left rotate position and vice versa. Since there space no brake lamp at every my friend checked for power at the brake irradiate switch. As soon as he accidentally bumped the ignition crucial the test choose flashed. I'm baffled.
