      A problem with the automotive relay

          Comments about RadioShack 12VDC/40A SPST Automotive Relay:

          When I received these relays (to use for trailer wiring on a 2014 Jeep Patriot) I was surprised that there didn't appear to be any spike suppression. A relay can produce up to 60v when turned off. The tail lights on most Jeeps are controlled by a computer and the 60v could damage the drivers in the module. Before installing I put diodes in reverse bias across terminals 85 and 86 to clamp the reverse voltage of a collapsing field.
          If RS is going to sell these as "automotive relays" they should have some sort of suppression circuit (diode or resistor) already installed.

            Comments about RadioShack 12VDC/40A SPST Automotive Relay:

            I used this to convert my Miata headlights to DRL's. This relay turns off the headlights while the starter is engaged and then turns the lights back on when the starter is disengaged and the engine is running. The numbers and connectors on the relay are perfect. The size is small enough to hide under the dash. Very pleased.

                Comments about RadioShack 12VDC/40A SPST Automotive Relay:

                This little relay can be used to recharge 12vdc lead acid batterys with only a small modification. After a few discharge-charge cycles you will immediatly see a marked improvement in the amount of time and life span of the reconditioned battery. Check out [...] website or on Youtube for full instructios.
