Alarm, Siren noise

[kuksuldo]

I purchased 1990 420 SEL from Ebay and just received.
mileage is 143600 with no history what so ever.
the car orignated from San Antonio, Texas auction.

I received yesterday and first thing I noticed that
every time I open the door or close the door or started engine or while driving( it drive me crazy),
it makes very loud alarm noise(siren horn with light blink) and stop once in a while and starts again.

after I get out of car and close door, the siren continue for about couple of minute and quiet.

I also notice that on the dash board, ABS indicator light is on all the time.

I suspect that this car might flooded previously but not sure, it is just guessing.

Please give me some technical advice.

Thank you all

Hi

If the light does not go off momentarily when first starting the vehicle then I would try the explanation below. If it goes off momentarily it a problem with the ABS system itself. When it goes of and comes again its carrying out a self test & has found a problem. Then you will need to get the system checked.

You may want to try (regarding the ABS ligh)t is the overload protection relay fuse. Silver relay situated in the middle or to the left hand side of the double bulkhead, with a red top with a fuse in it. Check to see if the fuse has blown.
