You are sure the red wire from my circuit is connected directly to the red wire out of the Z1 right?
Yep, unless I misinterpreted the diagram it goes something like this. Red wire from car connected to red wire from your circuit and the red wire from the Z1
Yah, that's right. Sometimes people will hook the red wire from the Z1 to the red wire on the radio harness, but then connect the red wire from my circuit to another 12v switched power supply which can cause issues.
thread said:ducatiboy said:I'm working on a slight modification for my circuit for these issues. So far you are the second person who has had any issue like this, but I'm sure I can come up with something.
There's bugs in everything that eventually get worked out so no worries.
Ok, not only do I think I know what's going on, I think I can tweak my software to work with this. Of course your's has the "old" (or curent) software. I'll make some modifications, try it on my truck and send you something to switch it out for. If you don't mind taking your dash out again to put a different circuit in.
thread said:One other interesting thing happened after installing it and driving around last night. When I'd put the car in ACC or start it the Z1 would think the illumintaion wire was hot even hen it was not and the lights were off. Pulling the constant fuse cleared.
That's very weird. You are getting the ILL wire off the little add on device aren't you? If you are then I would bet it something to do with that device. If not, then I'm not sure what happened there, maybe something to do with the Z1?
thread said:And, remember I mentioned my backup was not being seen by the Z1? Well, when the harness not conneted to the Z1 and the car in reverse the voltage on the wire was just under 12v where I'd expect it to be. If I plugged it into the Z1 the voltage was only 3.5. So, I tapped directly into the reverse wire instead of the one provided by the Dietz CAN adapter and now it works fine.
This scares me about that Can adapter. It sounds like they can't supply enough current for the reverse sense wire or the Z1 requires WAY too much current. I know most people think in terms of voltage. It's 0V when off and 12V when it's on, but the supply has to be able to source enough current for whatever is reading it. If you read the can adapter with a multimeter, it requires VERY little current. Since the can adapter supplys very little, then it's fine. But it seems like the Z1 requires much more current to "read" the reverse signal than the can adapter supplys. If the current needed by the Z1 is more than the can adapter can supply the voltage will drop on it's output. That's probably what's happening.
thread said:Oh, and vehicle dynamics isn't working despite speed pulse working. I rarely used it with the D1 so I'm not overly concerned with it and maybe it just needs more time to calibrate.
It should work, I think it needs about 50 miles of calibration or so (maybe less, I never timed it).
