79 Canadian BJ 42 imported to USA with 3B engine (dual batteries) installed. PO did a PAINLESS 24 to 12 conversion. The problem is that the driver’s high beam does not glow. Continuity on the bulb is good on both filaments. Voltage at the headlamp connector is near zero on high beam setting. Is the relay on the PAINLESS fuse block for the headlights as opposed to the factory relay? Thanks in advance.
