Based on all the info you have provided I think you need a professional to get involved here, I am not willing to "GUESS" what might be the issue or issues (more likely more than one).
Good luck
You have most likely "bought a duffer" I have 30 years experience with alarms.
!. Remove the internal battery, power down the panel.
2. leave "dead" for 10 minutes.
3. reinstate the power, Mains first then refit battery (Make sure terminals are correct for each wire)
4. Retest.
disconnect battery for about 10 minutes. then reconnect. gives alarm time to reset and everything should be working fine. when headlight went out it broke the circuit to alarm . now all you have to do is reset. ez
I had this problem one time with my 1988 560sl. I must have sent it to the shop 15 times when the alarm would randomly go off. The alarm would go off when I opened the door and sometimes while I was just driving down the road. The shop never could figure out what the problem was. They wanted to disarm the alarm, but I didn't allow them to do so.
After months of frustration, and spending nearly $1500 on visits to the service department and my alarm still going off every other day, my aftermarket cd player started to act up. Bingo.
I took my 560sl back to the shop and asked them to check out the wiring on my radio. Turns out, when Bestbuy removed my original tape player/radio, they clipped the original wire connections and attached new ones that would fit my new cd player.
In the end, I spent another $1500 on parts and labor to have all of the wires pulled out and replaced with new ones ordered from Mercedes Benz in Germany. 5 years later, both my alarm system and my aftermarket cd player work perfectly. Thanks to Bestbuy, my $150 cd player ended up costing me an extra $3000.
I don't know if this will help anyone or not, but it's worth looking into.
I had this same problem. I removed the battery and then unplugged it for about a half an hour. When I plugged it back in, I had to reset the date, time, year, time zone and alarm times, but the alarms now work!!
Sir, first check that the status of automaic updates of date & time on your handset. If that is off please turn it ON as is ur handset gets resetted from time to time it will take the service providers date & time which is almost accurate. If this doesnt help then try replacing the battery.IF that doesnt help then only one thing can be done A software Reflash. Take your handset to a repair workshop & have the firmware flashed. Thats the final solution.
Thank u
