Update on ZF trouble 87FC35

[Alan]

Well, after many hours this is where I currently am.

1. I have zero volts going to my ZF ECU.
2. The coach won't start. Now I'm pretty sure that's because
without voltage to my ECU, the coach doesn't know if it's in gear or
not. (I can jump my starter solenoid and it starts.)
3. I talked to Dan at ZF in Chicago and he was quite helpful. He
told me how to check voltage on the ZF. BUT he didn't know where the
ZF gets it's power off the coach.
4. I am getting volts out of my 75amp ignition relay with the key
turned on.

There are bunches of ZF wires behind the grill in the steering
column access panel. There are also two silver boxes with what are
apparently ZF wires going in and out of them. The boxes are about
4" x 4" x 1". However, I know these aren't the ZF ECU. It is
located underneath the push-button gear selectors by the driver. I
don't know if they have anything to do with power.

Questions (If anyone knows):
1. Where/how does the ZF get power from the coach?
2. Does the power go through the filtered power source under the
couch?
3. What would keep me from getting any power to the ECU?

Tomorrow I'm ordering a full set of electronic drawings, but in the
mean time my neighbors would appreciate it if I can get the coach
moved from the street.

Thanks,
Alan Johnson
