kyle, here is the number off of the sensor , 005 540324.
also i thought of a way to check if the gp's work.
check the voltage at the battery first, let's say it is 12.5 volts.
than pull all but one wire off of the gp's, so only one gp is connected, now while the volt meter is on the battery try to cycle the gp,s , if it is drawing current you should see a voltage change (lower) at the battery, lets say it reads 11.5, that should indicate a working gp, now check all the other gp;s the same way.....
