I could be wrong, but I think your voltage should drop more than 1.1V when cranking a "normal" engine with a standard starter load. I've seen voltage drop to 10V or even 8V during cranking. It would appear that your starter is not pulling the current. Perhaps you have a bad starter? A bad starter can look good when there is no load on it (like a bad battery), but it fails when you load it. Is there any way that you can have the starter tested?

I agree that the voltage should drop more...if indeed it were cranking. The starter is not turning the motor over at all. If I have the starter tested, can load conditions be simulated? Also will the DME relay have anything to do with this situation?

What I mean to say is that the starter motor will pull more amps when locked up than when spinning. The greater the resistance, the greater the load and the greater the amps it will pull. So if the starter motor is locked up, it should pull quite a few amps - possibly 200 amps - versus a starter that is spinning the motor. Electric motors drain less on the battery the faster they spin.

So by this logic, the drain should be huge and the voltage reading should be low, but it isn't. The numbers don't match. The starter is either bad or the connections/wires to it are faulty.

Well i have done the jump test from battery to starter. Starter turns engine over fine with this test. I have dismantled the ignition switch and cleaned all contacts. Reinstalled switch, still just clicks of the starter (or nothing at all). Removed DME relay and removed housing. Inside of relay looks like new. I noticed while working with ignition there was a click coming from the right of the accelerator pedal. Removing a panel just above the pedal i found two relays, one of which was clicking when the ignition switch was turned. Does anyone know what this relay does? and could this be the problem?

I just got one of my 951's together about 2 hours ago and I am having the same problem. I called it quits for the day. I will work on it tomorrow.
