Question about 2002 Toyota Camry

2 Answers

None of my electricals work but car starts

While replacing the Alternator on my 2002 Solara I failed to remove the battery cables so a short ensued, the car starts but none of my other electrical(s) work; dashboard, turn-signals, locks, windows, day-time-running lights, etc...

What Fuse or Relay did I fry? I checked all the regular or standard fuses, both under the hood and inside the car, and they all looked good.

    Thanks for the quick response

    Yeah, all the ones I could pull and look at.

    I did notice that the ALT 100A (don't know if it's a fuse or relay it's got a clear top and it's under the hood in the Relay & Fuse box) if it's a fuse the metal strip that completes the circuit is not completing the circuit, it's sticking right up and touching the clear plastic cover, tried to remove it but no dice so I left it alone till further advice.

    I'll pick-up a fuse tester, as per your advice, and post my results.

    Thanks again

    Yeah, like I just finish posting, I thought that was the issue but not being up to date on todays auto machanics, haven't worked on a car in over thirty years, and thus the reason I Google.

    I'll check back when all is done

    Thank you

  • jose_anto124 Sep 11, 2009

    Okay, so after careful examination I noticed that where the 100A sits, although part of the whole fuse box, it's actually a separate section that snaps into the box. I managed to un-snap it but could only raise it so far, but far enough to see that it was being held in place by two cables, securely screwed to the bottom of it. Given the resistance and the amount of tension it took to raise it, just to see what I saw, I?m not sure how I will be able to re-install it with ease. I think, however, that if I remove the whole fuse box this may give me better access to the cable(s), from the bottom, and allow me to release some of the tension. Not sure though but will post my results.

    Thanks again for the help.

Check your fusible links, you likely blew the ALT 100A fusible link. They are located in the fuse centers behind the battery.

They look like oversized square fuses with windows on top. You can usually visually inspect the damage through the clear plastic top, you can also pop the top off for a better look.

Note that most of them are bolted in from below so verify that before you go pulling on them!

The ALT 100A link controls your charging, headlight, fans. defogger, taillight, illumination, alarm, and keyless entry to name a few, and is the most likely culprit.

    Yeah the 100A is usually the culprit when that happens. It is usually pretty clear to see like you described too, so no need to test it when you can see the twisted shrapnel :)

    You will have to access the bottom of the fuse panel to unbolt that fusible link and remove it. You will likely have to get the new one from your dealer as well, many auto parts stores do not stock that link unfortunately. Your mileage may vary :)

Are you sure they all looked good under the hood? The large 50A fuse may be bad; test them, not just look at them. A fuse tester os $3 ... sometimes free with purchase of a small box of fuses.

It may also be an in-line FuseLink on the red wire.

Hope this helps!

When I connect the battery the blinkers come on constantly glowing, nothing else works, check the fuses, the alternator fuse is blown, replace that, connect the battery fuse blows again. 2007 solara.


Bad alternator or short in alternator wiring. You much need a wiring diagram. Is that the car? Was in an accident? You may have pinched wiring or a wire shorted to ground. Try new fuse with alternator disconnected, then with key on, connect alternator-watch for sparks, or clicks, -you might want to have the alternator tested, just to be sure. You have to start somewhere...
Maybe a wiring short in the blinker system? Or is the fuse blowing an alternator fuse?

Yes, it sounds like your alternator is short circuited internally. Replace alternator with high quality rebuilt unit
how does the alternater works
Alternator and Charging System A battery is needed to power the operating system of your car. Once the vehicle is running the battery is charged by the alternator which is driven by the engine. While in operation the alternator creates electricity, about 13.6 to 14.3 volts, and recharges the battery to its original state of charge. The alternator is one of the hardest working electrical components in your vehicle. When your vehicle is running the alternator is busy creating electricity to provide the engine and the car accessories with needed power. When the car is not running and your battery is severely discharged some electrical components may still operate or operate poorly. Typically, these components are designed to operate properly at 12 volts; if the system voltage is low it can cause erratic symptoms.
to check out how the alternater looks .
When jump started a severely discharged battery can cause the alternator to overload and internally fail. If this occurs replace the battery before replacing the alternator. This will help prevent a second alternator failure. Most vehicles use a multi-ribbed belt connected to the engine to rotate the armature inside the alternator. If the belt fails it should be replaced immediately. Belt tension should be taught. If it isn't, check the belt tensioner. It may need to be replaced or the incorrect size belt may have been installed. Either of these conditions can cause the vehicle to stall and not restart.

2002 Nissan Pathfinder _ Electrical Problems


Unusual the dealer can't or won't find the problem.
A mechanic would check everything in that circuit for shorts to ground.
Was the fuse blowing before the alternator and battery were replaced ?
Based on the wiring diagrams I would vote for a defective alternator.
The 10 amp fuse number 8 powers the cluster which also goes to the alternator. If the alternator shorts out internally it would blow that number 8 fuse and take the cluster with it.
The other circuits you mentioned are controlled by the key switch but are fused after the switch. So if the switch was causing the problem it should be blowing a 40amp fuse.
I would probably take the alternator off and have someone else test it.

What's draining my battery?


1: Faulty Battery: inspect and fill it with distilled water, if needed: battery may be shorted out

2: Alternator: the voltage regulator inside alternator will drain battery when it quits working: break unit open, and replace the regulator: or replace the entire unit with a rebuilt alternator.

3: Loose alternator belt, which slips and does not allow for enough revolutions to fully charge the battery - especially at night-time, when you are running your headlights and such.

Now, to do a test, which will tell you if the alternator has failed, in 10 minutes:

1) Simply loosen, but Do Not Remove, the battery post clamps / cables, from battery.

2) Start Engine.

3) With engine running, REMOVE both cables from battery posts (engine should continue to run) (if it does not / dies out upon removal of cables, then test no further): ensure to secure the positive post cable - wrap it with a rag, or set it on cardboard or rubber, so it does not ground: then reach inside, and turn ON your headlights: upon doing so, and highlights are ignited, if the engine dies out - if the engine quits running the instant you turn your lights on, with the battery cable disconnected off - that means that the alternator is Not Charging; that it is not producing enough current to run itself / maintain itself running / maintain the engine running; so it does not produce enough electricity to keep your battery fully charged - and, is in fact, draining your battery of any available current which was stored in it.

So, more likely then not, it's the electronic regulator / diode stored inside of the large alternator unit: but, because, your car is a 1990, the brushes on your alternator are shot anyway; so you are better off just replacing the whole unit and belt: and battery if need be.

I hope this helps somewhat: where, with ENGINE RUNNING at normal / higher idle speed, and BATTERY DISCONNECTED, and ACCESSORIES RUNNING, especially headlights and heater - the Engine Must Remain ON / Running - on solely alternator power.

In that: the battery is only required to start the car; stored energy / current for the purpose of starting the car, as supplied by the alternator - and adjusted by the regulator: a faulty regulator will fry your battery, by over-charging / allowing too much electricity to flow.

Good Luck,

Ray

My 2002 trailblazer shut down, and would not start back up. I thought it may be the battery, so I jump started it. It started, I drove up the road, and all the gauges stopped working, again the truck...


The alternator needs to be tested under load. I believe though that the problem is with a bad electrical connection. Remove the electrical connections at the battery, alternator, and starter and clean them thoroughly. Re-connect the connections. Also check the grounding strap from the engine to the frame. Check the strap itself to make sure it is intact and check the connections for bolt tightness.

My husband put a new battery on our 2002 toyota and reversed the cables accidently. now the car starts but none of the electrical works. what could the problem be ?


If you have electronic gages, it probably fried the gages. It most likely fried the starter and alternator as well. I would start by taking the alternator and starter to your local car parts place and have them tested. If the starter is fried, that may be why nothing else works, as all of your power goes thru the soelanoid. Circuit breakers may or may not blow from reverse polarity.

2000 solara 4 cyl. many electricals do not work, but car starts!


You blew your ALT 100A fusible link behind the battery in your fuse box.
It is a large white/clear fuse-type square with a clear top. YOu should be able to see the 'fuse' through the clear top has blown.

The fusible link is bolted from the bottom. so you will need to lift the fuse box and pop the lower cover off enough to access the screws holding it on.

The ALT 100A link provides power to all of the items you listed that are inoperative, but the car will run fine without it :)

Car won't start even after new battery purchase


Alternator problem, the alternator charges the battery when car is running, so it has probably died now. Was working at reduced capacity for a while, which is why you were only getting a partial charge for some time. Now you have an open circuit completely as alternator has failed completely, time for a visit to an auto electrician. PS replacing acid in battery with distilled water is not a good idea. It probably was time for a new battery anyway.
