944 S, 1988, won't start.

Hi,

My 944 will not crank - sometimes. Sometimes it does crank flawlessly, but sometimes, like this morning, it won't crank - especially when I need to go to work.

It makes no noise at all! The starter doesn't turn and the battery is good. Is there a relay?

Help!!

Kerry

No relay just the ignition switch sending current to the starter solenoid which in turn closes the contacts between the starter motor and the battery through that thumb size cable.

So if you have power in the car but no starter engagement/cranking then there is a problem with the cable, the solenoid or the starter motor.

If the starter is spinning but not engaging the flywheel the spring loaded device (bendix) is stuck or frozen.

The large battery cable does tend to corrode and increase resistance at the battery connection. Sometimes even breaks off inside the insulation.

I'd look at the battery cable connections, as noted in the prev post. Also note, there are three relays in some 944 cars, such as my '90 S2, which control "ignition" related components. Not sure how this relates to your problem, but if the battery cable is tight, and you have a good ground connection from negative terminal to the body, and a good connection onto the starter too, then I'd go after the ign switch as stated (and all relays)

Just checked the electricals to be sure. Straight shot from the ignition switch to the starter solenoid. Unless you have an automatic then there is a switch on the shift lever.

It was the starter. 7v at starter, not 12.

What? You mean the cable between the battery and the starter? Or?

Yeah, using a multimeter we measured the voltage at the starter when the key was turned to the start position and got 7v. When we measured the wires (not the starter), we got 12v.
