Dead 560SL

I'm Happy, just bought a new 86 560SL to sister my 82 300D Turbo last weekend after looking at several for over a month. The first few days were great now it's in the driveway needing alittle help, any ideas?
Electrically everything seems to work, even added a new Die Hard.
When I turn the key, all systems check out but then I turn the key the rest of the way, one quick click and the nothing happens. I've wiggled the shifter, checked starter wire connections and crawled around getting to know my new care and found nothing suspicous. Funny, it did it twice before but when I came back later, it cranked normally and started, not this time.

Sounds like a starter/solenoid problem. I group the two together as the repair for either is probably a rebuilt starter.

The proper test is to view the activation circuit for battery volatge and then to verify the lack of voltage drops on the positive and negative sides of the circuit.

The activation wire energizes a electromagnet that pulls the drive gear into the ring gear as the switch is simultaneously closed to the starter. At that point the positive side should have within .1 to .2v of battery voltage and the ground side (the case) should have .1 - .2v difference at most from zero volts.

Bad circuits on either side can interupt the motor as it uses a lot of current.

Also, if it has happened AFTER you changed the battery, check you bat cable connections ... a weak one here will do the same.

A simple DIYer test for that is to turn the headlamps on when trying to start...if the headlamps go off when the starter clicks,
you can suspect a poor connection at battery...
If they don't , SB's above post...
