[QUOTE="PRO2, post: 5944596, member: 610576"] Well the battery is the source power, so it the reading are higher at the alarm I would suspect the meter or battery contact where you are measuring. Not a worry yet. You indicated in one of your responses that your siren works fine when hooked directly to the battery. This being the case, the power or ground must be the problem. The alarm provides the power for the siren, so testing power and ground voltage at the siren will revile the issue. Connect your meter ground to the battery or a solid ground. Next, connect the positive meter lead to the red siren wire, as close as possible to the siren. Set off the alarm and take the meter reading. Now move the meter negative lead to the siren ground, again as close as possible to the siren. Set off the alarm and take the new meter reading. Results: If the meter reading is the same for both, but lower than the battery reading, check/repair your power connections. If the meter reading was higher with the meter negative lead on the batt, repair/replace your grounds. We typically recommend connecting all of the ground leads together for an alarm system, it makes it easier to "see" and troubleshoot when there's a problem. I was referring to the remote starter interface, mostly data these days. Just unplug it to test the alarm system. What is the year/make of the vehicle we are dealing with? [/QUOTE]
