Driving along in my '88 Volvo 740 - all warning lights go on!
I'm driving along in my old 1988 Volvo 740 and the dashboard lights up - seatbelt warning, wipers, brakes, park brake, light out, and oil. The car is running fine, makes no noise, nothing out of the ordinary - just one lit up dashboard and a freaked out young lady behind the wheel. Ideas? It was a very cold Colorado morning and I had just used my wipers before that to clear some frost. Perhaps a minor electrical snafoo?
Thanks for any help!

Re: Driving along in my '88 Volvo 740 - all warning...
My first thoughts are with the battery cables, or the alternator. You probably had the heater, wiper and maybe the lights on? That's a big load on the electrical system. Have the battery and charging system checked out! It's common on this model for the alternator brushes to wear out and the good thing is that they can be replaced separately of the alternator.

Hello. i have owned many 740's, 240's, 122's, and 850's. I have done my fair share of transmission swaps. The transmission tag is located right above the trans-oil pan and directly below the od seloind on the drivers-side. if your volvo 740 is a non-turbo, the transmission is AW-70L, if it is a turbo-model then it is AW-71L. Good luck :)
don't panic about the marks too much,find top dead centre on cyl no 1,good chance once you have you will find something that does line up between the block/timing case and the pulley. don't forget once it is fitted to ALWAYS wind the engine by hand atleast 2 times to make sure the pistons don't hit valves before starting.
The problem wont be your timing belt. you need to take out a spark plug plug it into your HT lead and check for a strong spark or even if there is a spark. check your contact breakers on the distributor as well
Horrible squeal. If my 740 made a horrible squeal I would be upset also. These ideas - timing belt has somehow slipped out of time. Easy check. One of the other belts are slowing the engine any of them can squeal:
The alternator belt
The power steering belt
The fan belt.
Does the noise occur only when driving? Does the engine sound normal when revving in neutral?
Does turning on the lights or a/c affect the noise?
Does the power steering work when car is standing? Is the squeal heard when turning the wheels.
A logical diagnosis will identify and eliminate these easy to fix problems.
