2000 Toyota Camry electrical drain

Hi there,

You will have to do a current draw test, put an Amp meter between the battery pos and the battery cable, (do not try and start the engine) with the doors closed and ignition off check the current draw. if over .25 Amps start to pull the fuses on at a time till the drew drops, that will be the faulty circuit, check the alternator as well as it may have a faulty diode causing a drain back, the alternator will still charge with this problem as well.

Okay, I checked the alternator today. It does put out power. I am getting a reading 0f 11.90-12 volts, at the alternators terminal.

So while spinning, the alternator is producing power. Only problem is that it is not transferring the power to keep the engine running via the distributor. Only the battery is powering the distributor while engine is running.

I checked fuses. Nothing blown.

So besides bad cables, what else could be the problem?

And BTW, if the battery terminals where to be corroded/bad, then how would that impair the alternator's ability to power the engine distributor? Would it just impair the ability to charge the battery?

My problem is that the alternator on its own won't power the distributor to keep the engine running. It's ability to charge up the battery is just a side-effect I believe. If alternator cannot get power to keep engine running, it won't be able to charge battery reguardless. Right?

Thanks for all the info so far everyone.

Hi there, this is not charging, you need around 13.5 -14 .5 volts at the alternator, i would get the alternator o/ hauled.
