Battery won't hold a charge . did replace the battery,alternator. starter.regulater , starter solinoid . will hold for a few but when you put on lights after tow days battery is dead again what do you think it could be ? thank you for any help you can privide
Looks like you have replaced all of the key parts, and then some. At this point I would verify that the alternator is charging the battery. With engine off, check battery voltage. Start the engine and check thre voltage again. It should climb to charging voltage, around 13.0 to 13.5 volts. If it doesn't, check all connections. On a vehicle this old, I would start with the ground circuits.

test battery with volt meter should have 13 volts. If lessthan 13 volts have alternator tested at local parts store (most do it for free) If battery voltage is ok check cable from battery to starter solinoid . if cable is good check negative battery cable going to body (grounding cable).if all is ok check starter solinoid (you may have to remove starter and take it to your parts store for testing. Most test for free like Autozone. a bad solinoid will do this . I replace the starter and solinoid as a unit it saves a lot of work.if this was helpful please leave me good feedback.
voltage regulator. it may be in the alternator, or remote mounted. ((the alternator can be charging, but if voltage regulator is'nt working then it won't allow voltage to get back to the battery to keep it charged
the clicks are a signature of a bad battery, since your is new, it probally is not bad, i would try to jump the car with cables, even though your battery is new, you dont know how long is sat ont he shelf before you took it home, may be weak, 1 good jump to get the motor going and the alternator will charge it right up so wont have to so it again....
the only other thing is the starting system left to look at if that dont work is the starter, try banging on it a little with a hammer, not to hard though, as someone turns the key, this will sometime free up a locked up solinoid.
There is only one wire common to the alternator and starter and this is the main+ wire which goes from the alternator down to the main feed terminal of the starter solenoid from there it runs to the battery + terminal.If you are replacing the cable use one of the same diameter......
If you have a volt meter check to see if there is a drain on the battery when the car is off, you can then pull each fuse to see which circuit is causing the draining. Sounds easy, but I have also seen cases where somone left change (a penny) in the cigarette lighter causing a short cirucit.
