Are these DC rated relays? Before you try another
relay..........get your analog VOM out . Use the X1 or X10 resistance scale . Measure the coil resistance in BOTH directions of an uninstalled relay.If it is different in one direction, those relays have a clamping diode across the windings to keep EMF from the collapsing magnetic field from killing delicate components downstream.{Your sand based DVOM can't perform this test reliably. } You have a 50 / 50 chance of hooking it up wrong and taking out the SCR for the Reverse relay on Card 1. Glad I could brighten your day. <VBG> Anyone else following along may wish to take note of this when using "upgraded" components. Know what you are using. :( RJ Kanary Bandi Bros.
