Does anyone have this system installed? If so has anyone ever had an issue with their's not going into reverse? Would love to find someone else out there who has my same problem. I've been through 4 control heads and 2 processors and the issue has yet to be resolved- ZF just sent another new control head to be installed!

Very surprised to hear about an issue with this set up. I can flip through my books tomorrow at the shop and see if I can track down a solution for you. What type of set up do you have? Single station or multiple ones?

Capt - Its been checked several times. Single station wired to a ZF 325 gearbox.

The control heads have been sent to Pinnacle Marine and tested for thousands of cycles and they have never had a failure.

I have 2 other systems installed on another boat and they have never missed a beat.

ZF is stumped - but that doesn't help me when I lose reverse gear coming into the slip or better yet its jumped into reverse by itself on occasion however it gets real interesting when it jumps into gear and starts increasing RPM's!

New control head installed yesterday and system checked again - we'll see!

Voltage supply issue maybe? Or a grounding issue. Those are the two things that pop into my head concerning your problem. I might have a voltage supply regulator, it came with a Clear Command but it might work for this instance as well if you have more than one battery bank feeding the processing unit.

The system is installed exactly as recommended by ZF it has the APS (automatic power selector) installed too....I appreciate the brainstorming - if you think of anything else let me know.

Power comes from 2 Deka Dominator gel batteries the issue could occur at any time its happened on the way out 1 minute after unplugging shore power or at the end of a 18 hour trip...no rhyme or reason.

Tossed and turned all night with this problem kicking around in my head, could very well be a pinched wire in the main harness from the controls. Have they checked for that? The wires inside the harness aren't much and a sharp bend or even a good sized adjustable wrench dropped on them while installing could produce a break which normally doesn't cause an issue, but when the Gremlins are just right and they move things down there in the engine room, the wire can separate (due to motion, or expansion from any source of heat, or just because they are finicky) it can ignore the signal so the control box is just sitting there wondering what's going on - that wouldn't show up as a fault. Next time you chat with ZF you might see if they would send you a cable and just rig it up right next to the original one installed, wire tie it loosely and see if that helps the situation any.

How is the "throw" of the selector valve on the gear? I have seen where it is hooked up and not getting to the proper detentes. Can even be sticky in the cable part. This makes it hard on the electric solenoid.

The solenoid arm length can be wrong, loose or even bent too.

The wiring has all been checked however, its original. The tech who was on the boat the other day (same guy since the beginning) has suggested that "if" it happens again he was going to install new wires. I would prefer an entire new system plus new solenoids on the trans. It really is a dangerous condition / situation.

Your points about the wire make perfect sense and we have talked about this, but for some reason ZF doesn't think thats the issue. They still believe its in the control head. Since they are covering it I'm not going to dispute Im just going to put up with it until they get it fixed. They have been good as far as that goes - I have been out of warranty for quite some time now.

Hi Capt. Thanks for the input however I think we are talking about 2 separate systems here. I am all "fly by wire" no cables, no arms to bend, etc.

It's quite frustrating however I still do prefer the electronic control systems over the conventional cable ones. :confused:

Sorry...The ZF electronic controls we have still have cables at the very end.

I'll sit down and shut up now:oops:
