I have a '83 Datsun (Nissan) 810 Maxima. Something has been draining the battery over night.. I've had the starter and altinator checked. Those are good. Hubby disconnected his amp from the battery. We bought a new battery a few weeks ago, and has been starting up great, but yesterday my hubby started it and it started fine but then last night he tried to start it again to go somewhere and nothing... The dome lights were strong, but all we heard was the starter clicking.. Then this morning, I tried to start it and nothing again.. The battery meter is at an 8. Help please.. Any suggestions would be very helpful.

You can insert a DMM (Digital Multi-Meter) set to 10 Amps to detect which circuit in your car is draining the battery. Connect the DMM between a battery terminal and one of the battery cables you have disconnected. The DMM reading should be less than 1/4 Ampere (250 Milliamperes). Try removing the circuit fuses one at a time to see which fuse circuit is draining the battery.
Sometimes a bad alternator will drain your battery, but make sure there's no courtesy lamps lit in the glove compartment and trunk.

The first thing I'd check is the battery connections.
Over time, scale builds up between the post and terminal.
Usualy the POS. is the culprit.
The scale allows lower current draw items like lights and radios to get enough power, but not high draw items like starters.
Remove the battery terminals and scrape the crusty stuff off the inside of the terminals.
It will also give a faulse reading to the alternator and won't charge right.

recheck the altenator sounds to me thats bad since you bought a new battery and that ran for a lil while then drained out because altenator is bad not making the juice you constantly need .go under neath the car with a hammer and bang on the starter a few times then try starting the car. check all your fuses. have your starter checked again. hope this works... good luck

Put an amp meter on the battery cable,then start pulling fuses one at a time until you find the circuit pulling the current.

it is the starter.it is the culprit of draining your battery.
and it is not doing it overnight ,it does it at the moment You turn on the key.
tell Your hubby to put the amp meter meanwhlie You turn on the key to " see " the starter during the drainage.
