It appears there may be a ground issue with the driver side headlight. We only tested the harness end of the connector(s) and tested two ways. First using both the probes on the connector with the red always in the middle contact (power) and probed the other 2 contacts with the black probe. We got ...

erikv11, I really appreciate that offer, but I have already purchased one used off of ebay this morning. I'm hoping to pop it in and have success, but now I'm not too hopefull. I am completely lost when it comes to diagnosing electrical and do not know how to use a volt meter. Could someone explain ...

I just can't imagine anything else in the system. I guess I'm going to have to take it to an indy and let them diagnose with a meter. I really was hoping for a eureka moment when I plugged up the new headlights.

As stated, the headlamps are brand new and I did inspect the connector on the harness, the contacts are shiny bright and not corroded. Could a bad relay cause this condition?

I unplugged, re-plugged, wiggled, etc. on it many times. I've also inspected it and there is no apparent corrosion. Have not tested it though.

A couple of months ago I noticed that my driver side headlight was very dim on low beam/daytime running and when I would turn on the highbeams it would go out altogether and throw the 'bulb out' indicator light on the dash. The passenger side headlight functions fine on both low and high. So I ...

Nope. Not sure what that's for (prehaps someone else will chime in), but the head mates directly below that area. It's a gasketed area and not in the oil path.

Any more info? I've seem to have a similar situation. Charged the system 3 years ago. Ran fine. This year had to do it again, but it seemed to be down two weeks later. Filled again thinking maybe low pressure valve might have gotten stuck, but now occasionaly it will blow warm, turn if off for a bit ...

You may as well check the three main mounts that support the engine. There's a small mount on the passenger side right near the crank pulley. When it fails it drops down allowing the whole right side of the engine for sink a bit (there's pics of this on Bay13 and maybe here too). Then you've got the ...

I'd actually recommend going back with Volvo pads. Have you seen this?
