Ensure main relay clicks when ignition is turned on and off. If no sound is heard, locate and remove main relay from main fuse block, in left side of engine compartment. Using ohmmeter, check continuity between main relay terminals "C" and "D" (terminals "A" and "F" on 626). See Fig 1 -Fig 3 . Continuity should not be present.

Using fused jumper wires, apply battery voltage to main relay terminal "A" and ground terminal "B" (terminal "F" on 626 or E" on MPV). Continuity should be present between main relay terminals "C" and "D" (terminals "B" and "E" on 626). See Fig 1 -Fig 3 . If continuity is not as specified, replace main relay.
