After installing a new battery she fired up and drove home fine. Have some serious issues and would really love some knowledge. Missing left brake light and turn signal. Bulbs are good. 4 ways activate for all amber lights. After trying to clean contacts on bulbs and fuses, now the starter will not engage and I cannot start the car. I don't know where the starter is located or if this is the problem. Haven't been able to locate a service manual. Any help with the electrical system and parts diagram would be extremely helpful.

Hi, the bets manual is the Bentley. First thing to know about the 528e is that it has a timing belt, which is good for 4 years or 60,000 miles. If the timing belt breaks the engine becomes a large paper weight. So you need to do that even after you figure out why the car is not starting. If you do not, I have a few m20 engines for sale.

The starter is underneath the intake manifold on the drivers side of the engine, it is a major bear to get out. But I would check to see if the wires are connected well. Then try hitting it a few times with a small hammer. If the soliniod died or got stuck this can free it.

Good luck.

I had a blonde moment apparently. I wasn't pushing in on the ignition switch when trying to start it. Problem with starting was my fault. I'll try to find the Bentley manual. While I'm waiting on the manual, do you have any suggestions about why the driver's side brake light and turn signal won't operate? Have tail lights on both sides and the four ways work all around. Discovered I have a bad side marker bulb on the driver's side. That's the only bulb I can determine is bad. Thank you taking the time to reply and to offer your knowledge.

You can get the Bentley manual here:

Tail lights - Assuming you've checked the fuses, twist them out and clean the contacts on the bulb holder and lens assembly. I usually rough up both areas with some fine sandpaper. You might want to bend the contact tab down a little bit. Positive ground if memory serves. You can get moisture in either assembly if things aren't tightened down.

This forum is more active and has a lot of good info:

If you are having to do that you are having a switch that is starting die. This can go on for a while.

Also if the wrong bulbs are used then it will throw the light.

Try switching the light holder to the other side to see if you still get the same light.
