Car Alarms: alpine sec-8027 security moduel, voltage spikes, negative terminal

Question
how do you initialize the system after installing it.the car battery was replaced and the system will not work.

Answer
Normally there is no initializing required.  Sometimes the units will lock up when a new battery is installed in a vehicle.  This is caused by voltage spikes when hooking the battery terminals back up.  Try removing the negative terminal of the vehicle battery, wait 1 minute, then press the terminal back on the battery holding it to the post.  This may resolve your issue.
