Hi, Glow plug relay on E 320 CDI - 2000. Need advice on how to check the
relay when out of car. Have a white wire coming from the ECU, pin 25 and goes to the relay`s small connector together with a brown wire, obviously
ground. Thought that when + 12 V power on this white wire and ground on the brown one the relay should click and make connections !, but it did not.
Anybody having experience with testing the glow plug relay?

PS. I am converting this engine to a marine engine and are now checking
all the sensors and electronics.
