89 Audi 100 - No Start, Battery OK, What next?

Ok - Here's the update...
Got a good charge on the battery, reinstalled it. Battery voltage is now
12.63 installed in the car.
Car starts! Charging voltage is 13.88 at the jumper terminal. Let it run for
30 minutes, turned off, restarted ok. Car is up to normal op temp, shut
down, waited about 5 minutes, then radiator fan came on for 30-40 seconds.
Then 5 minutes later, fan comes on again, but only for a split-second, then
turns off. Hmmmm...
I suspect that there is a drain on the battery that is related to the
radiator fan temp sensor or relays. This could account for the battery going
down. I'll have my mechanic check it out next week, as I don't have the
troubleshooting procedures for the fan controls.
So, Dave, you win! ( subject to verification by my mechanic next week! )
Thanks!
And thanks to all for your insights..you guys are great!

Re: Ok - Here's the update...
Glad it is back running!
Yeah keep an eye or ear open for that radiator fan coming on with the engine
off.
You can also make sure that no trunk nor interior lights come on and stay
on.
I saw one vehicle with a drain that was in the vanity mirror. The light
would not come on but there was still a drain there.

Re: Ok - Here's the update...
Your mechanic probably knows this but ...
The radiator fan is three speed controlled by voltages provided to is
through a BIG resistor pack on the frame just under the radiator. These
can go bad but usually do not.
Fan speeds one a two have separate relays in the main relay box under
the hood just in front of the drivers side windshield. Fan speed three
has a BIG double wide relay in the AUX relay panel under the dash by the
driver's left knee.
Speed one is operated when the AC is turned on and if it is a turbo it
runs during after-run cooling.
Speed two typically turns on and off if you are driving in traffic.
You would only hear speed three when the temperature is very hot. It
comes on when the temperature gage is about ten degrees to the right of
the center mark.
Any of the relays can cause the fan to run and take the battery down.
Two other components of the system to be aware of are a fusible link for
the fan ground just below the brake master cylinder. The other component
is the thermo switch that operates speeds two and three. It is located
just below the lower radiator hose on the back of the radiator.
