Hello i have a 1985 delta 88. For some reason my battery keep draining. I replaced the alternator and the battery. i changed the battery cables also. When i cut the heater on in the car my lights dims, blinkers stop working, radio cuts off,and the battery drains.Also the low coolant light, low fuel, and check engine light came on. all these problems accuried after my battery drained one day from listenig to music with the key turned backwards. thanks for your time, and i really hope you could help me solve this problem.

Battery cables being bad corroded,or a film covering the battery terminals,or a bad starter,but be surew of the battery and alternator.

Being you ruled out the alternator as a cause for the battery dieing, i would start looking into the parasitic draw on your battery when the car is shut off, make sure all your courtesy lights are going off and that none of them are staying on overnight, check your glove box light and make sure thats going off and not saying on, another overlooked item would be your trunk light, make sure the light in the trunk is in fact going off as you close the trunk, if any of these lights are staying on it will drain the battery and cause it to be dead the next morning....

COULD BE BAD BATTERY POSITIVE CABLE.BATTERY FEED WIRE FROM THE POSITIVE BATTERY CABLE BROKEN.YOU COULD HAVE POOR GROUND.YOU COULD HAVE BLOWN ALTERNATOR FUSE LINK OR FUSE BLOWN.CHECK ALTERNATOR FIELD WIRE OR BATTERY FEED WIRE FOR BROKEN OR DISCONNECTED WIRES.

Best to go to the GM site, and find the schematics. Armed with that knowledge, you can figure out which belts are needed for your 1985 Olds Detla 88.

-a.

just call it the headlight housing or bezel

Timing set a 20 degrees as factory specified.

Keep Backing off of timing 1 degree at a time until you don't have a pinging during acceleration.

Laging valve timing can not be fixed by simply advancing the ignition timing.

Check to see that you have less than 8 degrees of valve timing and you will be ok.

Hope this tip helps

Sounds like it!

Well, if the alternator belt squeaks a little, it cannot be actually charging properly, resolve that...

First steps would be to fully charge the battery and measure the voltage. Turn of vehicle Disconnect the negative terminal overnight, for a night or two.

If battery still dead, focus on the battery.
If battery is not dead, put a volt meter between the negative terminal and cable and measure voltage... do not be mislead by interior lights, or clock, pull those fuses, during testing...

Anyways, keep going until you find a drain.

The alternator has diodes that can cause a drain...disconnect for testing purposes...

NEVER run the vehicle with the battery cable dicsonnected.

Doc

what is needed is not worth it.getting new motor is cheaper.

check for a bad battery connection or bad battery and then the startet the fuel pump wont keep it from turning over
