I have one of those fitted in my car, and the users manual states that
it is possible to switch between voltage sensing mode and no voltage
sensing mode by setting a switch. I don't want it to be voltage
sensing, but the alarm reacts on voltage changes in both modes :-(

Does anybody out there have any suggestions to solve the problem
(without a separate battery for the alarm), or does anybody have acces
to a Service Manual or an electronics diagram of the thing?

Any help will be very much apreciated.

Henrik.

It sounds like you misunderstand what is being talked about. Voltage
sensing is when the alarm detects a change from zero voltage to some
positive/negative voltage level. No-voltage sensing is when the alarm
senses a change from a positive/negative voltage to zero voltage. In
both modes, the alarm is reacting to a voltage change.

Not being familiar with this particular alarm, I cannot say how to
turn off current sensing... contact the manufacterer or a
retailer/installer for that. But, if nothing else, you will probably
find that if you relocate the current sensing wire to the + terminal
of the battery instead of the fuse box (common spot), the current
sensing will be desensitized quite a bit... though this varys greatly
from vehicle to vehicle.
