Ram 3500 Relay
Designed as the smart electric switch of the truck, the Ram 3500 Relay allows low-power signals to quickly and reliably control heavy A/C and cooling parts. The conventional electromechanical type employs an internal coil magnet to close the contacts upon a demand from the control module for airflow. Hence, the battery voltage is sent to the fan motor only at the time of requirement, thereby preventing overloads. Later models were outfitted with an advanced solid-state Relay, which replaces the moving parts with semiconductor gates to facilitate a rapid response and enhanced vibration resistance, and fits into the same mounting slot. These upgrades let the Ram 3500 handle extreme towing heat. All heavy-duty Ram 3500 models use several of these units as part of the operation. The fan Relay is the first unit that spins the fan of the radiator. Second is the blower motor Relay that powers the unit for cabin airflow. The final component is a safety Relay that cuts the power if sensors detect a fault. Replacing a worn-out unit will often restore climate control without the expense of a new compressor or motor. This is exactly why this little part is so important on work-oriented Ram 3500 trucks.

Ram 3500 Relay Parts Questions & Experts Answers
- Q: How to test and replace a faulty relay on Ram 3500?A:Relay has been used in many electrical accessories of the vehicle to transfer current to a component. If the relay is not functioning, the component gets faulty. Most of them are found under the engine compartment relay and fuse box while others are installed in different wiring harnesses hidden behind an instrument panel. When there is reason to believe that a relay is faulty, it can be removed and checked using a tester. In this kind of vehicle, majority of relays use an ISO terminal designation which means International Standards Organization. The numbering of these ISO relays' terminals indicate their common circuit connections and functions. Different relays come with two main kinds of terminal arrangements. Among the terminals on these vehicles' relays, two belong to the control circuit while others serve as power circuits. When activated through energizing the coil, it produces magnetic field that closes bigger contacts in its power circuit so that loads have power supply inside such a system. Control circuit usually contains two terminals 85 and 86 where terminal 86 relates to battery positive (B+) voltage and terminal 85 refers to ground if at all relay has a diode across it. Terminal 30 is typically attached to battery voltage (B+) source for the load circuit while terminal 87 goes on ground side of that same circuit.If you suspect that your relay may have failed, you can remove it from your vehicle and test for continuity between the relay's power-circuit terminals with an ohmmeter.If any continuity exists between terminals 30 & 87 when deactivated then de-energized.So what will happen next is connecting one jumper wire between fused a jumper wire between terminal 85 and another between power window motor connector should make click sound.First test for resistance across control coil using ohmmeter after separating relay from vehicle.Checking for continuity between power-circuit terminals by using ohmmeter.With all this done, I would replace my damaged Relay if it could not pass any of these examinations.
