Hi all,
I am having some issues with the alarm in my R129 and would appreciate any help on how to bypass its fuel cut off.
It's a 1997 build car with the factory fitted debagged scorpion alarm control unit GM11221MGH and siren JS1064MGB
I opened up the siren and the batteries have corroded , but as I understand it shouldn't affect the operation.
I have also opened up the control unit and the relay inside it doesn't seem to operate, I removed and tested it and it functions correctly.
The car starts fine when I bridge the fuel pump relay contacts but this is not a permanent solution and I can't seem to find a wiring diagram for the alarm.
Any ideas
