Hi again! Well the replacement of the TPS worked great. But now a weird
I was driving and my lights shutoff and the instruments starting going crazy
and the battery finally died. No problem!! I put a new battery in and it
starts right up!
BAD news: There doesnt seem to be power to the headlights, windows, ac, and
heater. The stop lights, gauges still work fine. I checked some of the
fuses under the hood and couldnt seem to find anything wrong.
Should I check them all? I have no clue why they just all stopped working.
Any ideas? Thanks!
1998 Hyundai Elantra(dam electronics!)
1978 Ford Fairmont(no heater/ac but at least is EASY to fix!)
Check the large main fuse under the hood. It's probably blown, preventing
the alternator from charging the battery and the other items from
receiving power. If it's not blown, check the bolt-in contacts to be sure
they're not burned.
Ok, I checked the fuse both visually and with an ammeter and found its ok.
You are right in that the attery isnt charging and the other items have no
The contacts to the fuse you mean? or is there something else like maybe
the alternator is dead?
I really appreciate any and all help! :)
The alternator being dead wouldn't cause the other items to not work.
You'll want to check to make sure you have proper power to the alternator.
Pull the connector and turn the key on and check with a test lamp. One
wire should light brightly and the other should be a little dimmer. With
the voltmeter, one should read basically battery voltage, and the other
should read up to 40 percent less. Also check the big voltage drop on the
heavy wire if you haven't found a problem yet. Clip one lead to the bolt
terminal on the alternator (being careful not to short it to anything) and
the other to the positive terminal of the battery. On the voltage scale,
you should not read more than 0.5 volts. More than that means you have
excessive resistance in that wire/circuit somewhere.
Theres 2 main boxes right? I checked both the one inside and out and all
are good. I am totally stumped since I seem to be getting power to the
There has to be something I am missing. :)
Maybe a fusable link or something. Since the alternator isnt working also,
maybe the voltage regulator? (wherever that is)
I guess this is what I get for buying a newer vehicle! bleh
I FEEL LIKE A DUMBF^&%!
Ok, I go to check the fuses, they are all good, but since I checked some of
them night it could be one was misplaced. Yeah, one was misplaced, but I do
believe the alternator is dead. Which was the problem in the first place.
Thanks Hyundai tech for helping! You rock!
Next question: WTF do the dam alternators cost almost $200!!!??? Seems
like Id be better sweating and freezing my butt off in my old 78, then this
dam money pit. Maybe I should have bought a toyota or nissan....Live and
learn i guess!
Changed one in my 97 Elantra a few months ago. A bosch rebuilt ran me right
around $150.00. Now I need the transmission worked on, no doubt rebuilt:(
unless hyundaitech has some tricks up his sleeve:) reverse, 2nd and OD is
gone!!! 1st and 3rd work fine!
Thanks Rick! Now you made me even more nervous about this car! :)
I guess ill just drive it until something major goes(prob soon eh). At that
point ill tow it to the junkyard and buy a nissan or toyota.
Don't worry too much about it Shawn unless you've got higher mileage on your
Elantra. My Elantra has 170,000 miles. I use it every day for work and to
be honest about it I've been pretty much pleased with the little car. I
guess I'll get it fixed, but I hate to put $1000-$1400(quotes I've got for
the trannie) into the car. The engine itself is strong, doesn't use a bit of
oil between changes(3000 miles) and the body and interior is still in good
Yeah this one has 59,000 miles. The sister-in-law is hard on cars but the
engine does run strong. Im going to replace the alternator this week, just
doesnt look like fun though. :) (small cramped space)
Soon as I got this car I changed the oil to 10w30 synthetic. I did the same
with the 78 ford fairmont. I think it will help them last longer.
Actually the job isn't as bad as it looks. You have to drop the plastic
shroud underneath the car first and that will open things up pretty good.
Take the power steering pump loose and just move it off to the side out of
the way. The alternator has to come out from the bottom too. After doing it
once I think I could remove and replace one in a about 30-40 min. and I hate
working on newer cars:(
Yep that's my dilemma. The engine is still very good and the body isn't too
bad either, in fact it looks pretty decent when it's cleaned up. I just
hate throwing a $1000 into it knowing the car has little resale value. Of
course I by my vehicles to drive:) and pretty much use up, but still I'm
thinking I can use the money that i would spend on the transmission for a
little down payment on something newer and with less mileage.
Why not take the alternator to a local shop for a quote? Theres
absolutely zero 'magic' inside there, compared to any other
manufacturer's alternator. I've found this generally costs about half
as much as a cheezy 'exchange' alternator from a parts store, and in my
experience, works better.
The reason they're expensive is the same reason they're usually not
locally stocked parts - they're not regularly needed enough to be worth
Thanks for the tips. :)
It went pretty good. I CANT believe she never had the belts changed. They
were cracked so bad that im surprised they even worked. So i replaced all
3. It runs good now. YEAH!
