1987 300TDT with Euro lights.

High beams will work very sporadically, about 5% of the time.

Checked the combination switch have continuity for both flash and high beam. Replaced fuses and bulbs.

Checked the high beam fuse, had 12+Volts when I switched the high beams on.

I'm assuming because of this that the exterior lamp monitoring relay is fine, please let me know if this is not true.

So where too next? I think the ground would be the problem but the low beams work 100% of the time as do the fog lights.

Any suggestions are appreciated.
