how do u test to see which ones are bad? I thought that I had read it once, but cannot find it now.

thanks in advance

Either an amp clamp to check current draw or the backwoods method, unplug the glowplug, take a wire direct from the batt and touch the blade of the glowplug. If its drawing juice, you will see a small arc when connected.

you need to test the resistance from the spade connector to the threads of the GP, I cant remember how many ohms of resistance is good, but I think its somewhere around 50 or lower.

use a test light. unhook the gP wire, clip test light clip on + Side of battery, touch tip to GP terminal. If it lights, its good.
