Thank you all - I thought I was fighting a rare problem I caused myself! I have a 1991 Corolla that my daughter-in-law ran out of oil and spun a bearing. I replaced the engine with a used 1500cc engine from Japan (bought over i-net) and it's been running good for several thousand miles.

The alternator light and the brake light have started coming on together, first occasionally, now constantly. Until yesterday, no other problems, but I needed a jump to get it going yesterday after work. The lights were off on the way home, except when the RPMs dropped at idle. It started fine this morning, but the lights were on again. I don't know what it'll do after work today.

At least now I have a place to start - sounds like I need to check the battery (it sat, charged, in my garage for 3 years... then started the current motor and has seemed to be fine) then the alternator and finally look for an intermittent short. I'll add to this post after I fix (hopefully) the problem. In the old days we used to have to polarize the alternators - or was it generators... who knows. Anyway - thank you all!

I just bought a 1993 Toyota Corolla auto trans, but it moves off very slow. I've got the tranny check and it's good. The computer is not sending power to the tranny, so no power is going to the shift solenoid. I've changed 2 computers and still have the problem, it stays in high gear and starts off slow, but speeds up and never changes. The computer don't send a signal to the tranny because the tranny is not getting power to the shift solenoid. I don't if I explained it right. If anybody has any ideas about this, please help help me. Thanks.

I have a 1997 Toyota Corolla with 162,000 miles. As most readers have commented, a very reliable car. Recently, the battery light comes on intermittently. When the light comes on, the headlights get brighter and the vent fan inside the car speeds up. I replaced the alternator and battery. I have checked battery terminals and wiring and three ground connections to the engine and chassis. I noticed the hot wire coming off the alternator terminal had about two inches of insulation burnt off it, but the wire seems to be in fairly good shape. I still have the problem with the battery light coming on intemittently. Any suggestions?

I have an 87 Toyota Corolla, brand new starter and battery, started up on Saturday no problem. I went out to start it up on Monday morning, and the engine's turning over, but it won't start...

Any suggestions?

Check the wiring harness. If it is burned together, it will charge until you burn up the battery.
