Bambi + a facelift = No parklamps?

[Layne]

I hit a deer on the 4th... So I went to the junkyard today and got a grill and a headlight assembly. Thing is, I have blinkers, but no parklamps. The drivers side is super fast and all the bulbs work. Do I have a bad wire somewhere or the wrong bulb or something?

[Irish_Alley]

bad ground sounds like. i had a bad ground on my 94 the ground was on the passengers side. but if i turned my head lights on everything would turn on high and low didn't have turn signal at all if the running lights were on and if they were off everything worked just fine

a superfast blinker means low resistance in one of the "other" blinker signals.  That could mean a burned bulb or the circuit just is not complete in some other fashion like Irish said, could be ground.
Take a voltmeter to the socket of the light that isn't working and see if volts rise and fall.

I assume you mean high resistance in one of the other blinker signals (infinite resistance on a bad bulb).  He also said that his bulbs all work.  It should be a bad ground or a corroded terminal or other cause of high resistance.  Bad connection somewhere.

Upon further inspection, I had a bad fuse. Visual inspection just doesn't cut it sometimes.... So I have lights everywhere and all is good, but my left turn signal is still quick draw Mcgraw. Some of the insulation was peeled off a wire, but I taped it up good. Should I Investigate that? The copper was ok, just the insulation was missing.


Also everything was okay before the deer, so a ground or a corroded wire wouldn't be the case, right?

Mine was was a bad ground after my encounter with Bambi...  Knocked the ground wire loose on the core support, at least that was my problem...  It was hard to see, but after I took the grill back out I saw the problem...

I had some real fast turn signalling a while back and a new flasher took care of it.

no a high resistance would cause a slow blink. But it could still be your ground. Usually fast blink is cause a bad bulb are you sure all the bulbs light up. With just turn signals on try you 4 ways and match both sides

??

infinite resistance on a bad bulb?  no, there will be no resistance on a burned out bulb because the circuit won't complete. Like a fuse, the little thread inside the glass breaks clean = no resistance.

exactly Irish.  Try using a long extension cord and put an appliance on it that draws lots of amps. The cord becomes warm or hot....why? because of high resistance--the appliance will not work efficiently (slow)

So, as i said in my first post, a circuit with low resistance will speed up things a bit elsewhere in the circuit.  

[jaredts]

Infinite resistance is another way of saying open circuit.  A blown fuse and a blown bulb are both examples.  Conductivity is the inverse of resistance.  No conductivity is infinite resistance.  No resistance is infinite conductivity, which is impossible.  A bad ground or a corroded connection create high resistance.  Think about that bulb or fuse's filament:  make the wire smaller and smaller resistance goes up.  You could make it small enough to have megaohms out the wazoo until the wire is so small it doesn't exist.  The huge amount of ohms of resistance becomes infinity.  The correction I was trying to make was an academic one and not really helpful.  Sorry.

update:  Here's something that might be good reading:  http://mgaguru.com/mgtech/electric/et104.htm
This explains how the flasher works.  If you have a blown bulb that is one less path for current flow.  This increased resistance from a blown bulb (fewer paths) causes the heater to heat up more quickly and flash rapidly in the flasher.

[Layne]

All lights work, and the 4 ways are slow and normal. On a side note, the left side is way brighter with the parklamps on. Haven't had a lot of time to investigate with work and whatnot.

[Irish_Alley]

did you see if all the bulbs are the same what is it 2357?

[Layne]

All the bulbs are correct, although the drivers side is all orange, and my pass side has 1 orange and 1 clear

[Irish_Alley]

Since you have "clear" lenses and all 4 bulbs are turn signal they should be all amber not clear bulbs

[VileZambonie]

Infinite resistance is imeasurable resistance ie open circuit which is true. However one thing to keep in mind is that in a parallel circuit the circuit total resistance will change if one bulb goes out but the circuit will still function properly. With a signal circuit an open bulb will allow the flasher to cool faster resulting in a faster blink.

Think of a 2 2Ω parallel circuit with 12A vs a 3 2Ω parallel circuit with 17A

If you want to calculate use the product over sum formula to calculate ckt total resistance or the recipricol formula if the circuit has more than two parallel legs.

Sounds to me like he has a bulb or socket issue. Did you verify all of the filaments illuminate in the dual filament bulbs front and back?
