#55 of 81 battery cable question 2000 camry
Dec 02, 2009 (9:18 pm)
First of all let me say I don't feel so bad, my battery just died and i had it almost exactly 3 yrs.
My question is about the battery terminal connectors and battery cable to the terminal connector. My terminal connector needs to be replaced, (Toyota's set up sucks btw). However, there is an additional small wire piggybacked onto the connector. I am not sure of the thickness, perhaps 1/4 inch or about as thick as a telephone line.
I am wondering what this is for? It appears to run along the main positive battery cable and into a part of a wiring harness. Could it be for ground or some other reason? At one time the car had an alarm system, which I had uninstalled. Is it perhaps a leftover hot wire from a poor uninstall. Does it make sense the wire would coincide with the hot battery terminal plug wire?
Any information would help.

1/4" would probably be the alternator positive post output wire. It generally runs to the battery positive terminal at the starter solenoid or directly to the battery as above.

Thank you... I took it to a friend's shop and they replaced the terminals, but used the same OEM setup Toyota had, said it could / should not be changed.
#58 of 81 Changing Car Battery problems
Dec 26, 2009 (2:24 pm)
I just changed the original battery in my '02 Camry, and two problems occurred. The speedometer needle has swung all the way to the far right, and is no longer working, and the idle speed has dropped to almost nothing, making it hard to keep the car running. I understand from reading other posts the computer may need re-setting or re-programming. Is there any fix I can do from home, or does it need to go to my mechanic.
Thanks for any help.

Something's wrong, because the speedo needle won't relearn its original function. Also, the idle speed can drop, but not to the point of stalling. Was all power off when you changed the battery (lights, etc.) and did you remove the key from the ignition switch?

Check to make sure you didn't blow a fuse, specifically these three:
- 10 Amp IG2
- 10 Amp Gauge 1
- 10 Amp ECU-B

The key was out of the ignition, but it's possible the headlight switch was on. I don't think the headlights can draw any power without the key being turned on first. The drivers door and the trunk lid were open, meaning the dome light and trunk light would have been drawing power when I hooked up the new battery, but the trunk light is out. The idle has returned to normal, but the speedo needle remains buried all the way over to the right, with no function at all.
When I hooked up the new battery, I noticed something was drawing a little power, as I heard the light sound of electricity as the negative cable neared the negative post. The positive cable was hooked up first. I assume the power draw would have been the dome light, as the drivers door was open, and I have the dome light switch set so the dome light comes on when the door opens. I don't think my trunk light is working right now, the bulb probably needs changing.
I talked to my mechanic, who hasn't heard of the speedo problem before. He said the idle speed needed to be relearned, as it's controlled by an idle motor.
I'm going in for a 30K service later this week, my mechanic says the speedo problem is easy to diagnose.
I'm wondering if its an electronic speedo or traditional cable actuated?

I checked the three fuses, none of them were burned. I also checked Guage 2. I managed to drop a fuse under the battery tray in the process, but I substituted a spare fuse from the fuse case under the hood.

The speedometer is electronic.
Sensors on the wheels and transmission.

So, one or both of the sensors may be malfunctioning,, or the gauge itself is a goner. Maybe it's coincidental to changing the battery, and the malfunction isn't related to changing the battery at all.
That would be quite a coincidence.
