remote starts

test the wire with a DMM in AC voltage mode with the car off, it should read around 0 volts. now, start the car and test it in the same mode and you should get something around 6-7 volts.

i just installed a crimestopper remote starter in a 2002 trailblazer and cant get any response out of the remotes, tried to program them and they will not program, the system enters program mode but no response from remotes any ideas?tim

this is gonna sound real stupid, but my dmm has many differnet values for the AC voltage, which one do i set the dmm on

depends on your meter.. mine goes 2 then 20 so i obviously set it on the 20 scale... it  only has to be able to read 10 volts AC max... so set your meter on whichever it allows to do that....Kevin Gerry

well, the different values of AC voltage you have should represent the different ranges. i know know which model you have but choose a range that "just" covers the 6-7 volts. there will probably be a 0-10 volt range. if so, use that. you probably don't want to use a 0-50V or 0-100V range because the 6-7V value will appear very small. and you don't want to use a range that's too small (i.e. 0-5V) because it won't show the AC voltage value correctly if it extends beyond that range. the ranges i gave you are purely fictional as they vary with different DMM's but hopefully you get the point now. i'm lucky because i purchased a DMM that automatically adjusts the range so that i never have to mess with it.
