TIU

FM Former Member

i have all kinds of problems. First i replaced a diode as my TIU died on me.  After repair it would fire up engines but wouldn't add them or run them. Did the upgrade to version 6 but nothing worked. So I saw a TIU new for sale on eBay for 70.00 but it was the older version. Couldn't get the computer to recognize it to do the software upgrade. Plugged it in to my z-4000 and noticed the amps were way down. Seconds later heard a pop or fizzle sound and it's dead. So two TIU units dead - had one last year fry its terminals and scrapped. What is going on? Is my z-4000 bad?  I don't see any fuses in the older version TIU so I guess there is  no repairs to be done   At this point I'd rather ship everything off to a repair shop to see what they can figure out the problem is  my way is too expensive and frustrating  anyone up for the challenge?

Not to be offensive, however, I think that it's worth noting the following.

First,

i have all kinds of problems.

Your problems are primarily self-inflicted:

  • You mis-repaired your first TIU.
  • You bought a replacement TIU on E-Bay.
  • The TIU you purchased on E-Bay was a 14 year old model that has a history of being prone to failure, and apparently had issues.

Second,

At this point I'd rather ship everything off to a repair shop to see what they can figure out the problem is  my way is too expensive and frustrating

I couldn't agree more. There are several people on this forum who can help you. Hopefully, they will respond soon. Good luck!
