Intermittent drop out of low and high beam head lamps.

[AQUAR]

Hi All,

Was driving along and suddenly the low beam dies and comes back on a bit later.
Only started to happen this week, but has been intermittent since then.

There is a 6 pin dual relay (2 X single pole single throw) plus a 4 pin single relay (1 X single pole single throw) that makes up the light circuits for park - low beam and high beam.The 6 pin controls the park lights and low beam plus power to the single relay (presumably high beam relay?). I pulled out both the relays and they seemed to test out ok on the bench.

But the problem is still there and when I tap the relay the low beam contact sometimes chatters.
So either the coil is partially burned out or there is a bad earth connection via the light swith.
I am hoping its the relay and would much appreciate any suggestions as to where I might get a hold of one.

The 6 pin relay is mirror wired and seems to be able to be reversed in the plug (?).
If so it might help pinpoint if its a relay coil problem or bad earth problem (ie stuffed switch).

The complete circuit is a bit of a mistery as it doesn't match that in my manual.
If anyone has a wiring diagram for a Sigma GJ SE sedan with electronic ignition that would help a lot.
