I have a 92 40 HP Johnson. I need to check the 2 relays on the Starboard side of the engine. The Switch on the side of the engine works but the throttle switch does not. I tested (Ohmed out) the throtlle switch and it is good, and I have power there. Do the 2 relays just pull out together as one unit. Do I need to unscrew something or do they just pull out to unplug?
