Yesterday the car was outside the garage for a few hours in a light drizzle.
I get in, turn the key and evrything dies. Recharged the battery and evrything's fine.
I drive a while, flash the high beams and the fun starts. The "check engine" light turns on and the engine revs up slightly.... then after about 20 seconds the light goes off and the engine is honkey dory again.
So of course I have to do this again, flash the high beams and the same thing happens again, "check engine" light comes on, engine revs slightly and then 10 to 20 secs later all is back to normal.
So of course I flash the high beams again and this time the car and battery die.
I get out recharge , and its all good
I drive around for about half an hour and turn the car on and off a few times without a problem
As I pull in the driveway I get brave again and flash the high beams...
Nothing happens, no "check engine" light comes on , no engine reving ...nothing, the car runs just fine.
I am thinking I have a short, I just wonder where the hell to start looking for it?
