I have an completely dead car battery and i need to know which setting is required in order to use the 2/15/125amp starter charger?

Disclaimer - I accept no responsibility for anything I say here. I may be wrong, so use your judgement on taking my advice.
Advice - First try the web and/or the manufacturer for the manual for the charger - if that fails, what I'd do for myself is...

125 for starting the car (ONLY, not charging the battery) 15A for charging dead/low battery 2A for maintaining battery
If 125 doesn't start the car, I'd call AAA

Schumacker battery charger problem?

You are charging. The meter corresponds to the level of charge in the battery. Try setting to 10 A for 4 hours, battery should be half-way up. To determine if battery id dead.. leave battery off charger once it is fully charged...test with a voltmeter after 10 min.....battery should still be above 12v...after1 hour it should still be above 12v...if not battery is spent.

Do you have headlights if you turn them on. Sometimes if a battery is clear dead and you jump it and it will depend on the gauge of wire in the jumpers whether it will start right off or not. Another scenario is the battery you bought is not good or fully charged. If you have a battery with less than 11 volts it probably won't energize the starter.

Where are the fuses and relays for the fuel pump and starter?

sorry sir my computer crashed on me last night i finally got it going again . now you have the 1989 lincon towncar. darn i thoutht it said 1999 last night. anyways no problem, that year they did not have a relay for the starter . what they had was a starter solenoid located on either the fire wall or the fender, just follow the wires from the starter up to the solenoid im betting 10 to 1 your problem is in that nifty device. now you can check it to make sure it is the problem with a screwdriver just take the little wire (it just plugs to it no nuts holding it on ) and touch it with the screwdriver now at the same time touch( while still touching the little probe)the large wire (coming from the battery) if nothing happens then the solenoid is bad, just for grins to see if the starter is working touch both big terminal at the same time and watch her spin over if it doesnt then starter is bad or the battery is dead good luck and sorry for the delay i appreciate your patience
