glow plug controller?

My pickup is a 85 K20 and after changing the starter, the glow plugs will no longer work. I can control the plugs manually and when I do this when trying to start the motor It will pull the starter way down. Does this sound like a controller gone bad?

The first thing I'd do is ensure all the connections on the starter are tight, as power for the ignition-hot circuits is taken from the large stud on the solenoid.

the glowplug controller gets power off the drivers side battery and if it pulls down when you do it manually that would suggest that maybe your not getting powerout of that battery
