We have an on going electrical fault when ignition is on or starting.
When we turn the key the accessories sometimes drops out including windows , radio, dash vacuum,etc.

If you ignore it after a while it comes good.
The other thing to do is turn it off and on till the fan / gauges start working.
also to mention some times when started and all is good and you go though the gears to neutral / reverse it can sometimes cut out. as above.
put in neutral and start again.

We thought we had tracked it down to a dirty fuse holder / carriers.
an auto sparky suggested it because there so much draw on start up there are 2 ignition relays,
When we tried the OBD diagnosis it didnt even show up ?

Need more info.

When the key is turned to ACC exactly what specific items drop out?

When the engine dies what electrical items also drop out?

Does the dome light continue to work when any of the above happens?
