Omega Electrical and Audio Help / Re: Glow Plugs Problem

« on: 11 March 2011, 13:55:16 »

Many thanks for your comments. Having checked again it looks like the relay has blown and also the glow plugs. The resistance measurement from the output of the relay is very high (several megohms) to each glow plug lead. That was an interesting point that perhaps some of them may have been blown for a long time but had no effect on starting.

What's the best way to get access to the glow plugs? Is it necessary remove the inlet manifold?

Thanks.

Omega Electrical and Audio Help / Glow Plugs Problem

« on: 10 March 2011, 14:47:19 »

I have a 1999 2.5TD estate that will not start. Fuel seems fine at the output of the fuel filter. I have disconnected the glow plugs relay and measured the resistance to earth of each glow plug lead. It measures open circuit, suggesting that all six glow plugs are blown. That seems hard to believe. The voltage at the output of the relay measures 12V before switching on the ignition. I would have expected that to be OV. Makes me think the relay has blown and that's taken all six glow plugs with it.

Tracing the wiring from the relay to the glow plugs it seems to disappear into a king of plastic covered distribution box on the engine crank case and the glow plug leads come out from there. That's very hard to reach under the inlet manifold and I can't check if there is anything wrong in there.

Any ideas will be appreciated. Thanks, Jim

General Discussion Area / Air Conditioning Fairure

« on: 27 July 2008, 12:27:18 »

The air conditioning on my 1999 Omega 2.5TDi estate suddenly stopped working. Are there any common reasons for this?

Around the same time the front passenger area of the car was flooded. The water drain holes near the pollen filter were clogged up with leaves and some heavy rain left a lot of water in the car. I'm not sure if that had something to do with it. Are there any electrical components near there that could cause this?

Any comments appreciated. Thanks.
