Mercury Optimax 90 goes out

[HornBoats]

Hi.
I have a strange problem.
Sweeping after pressing the i button trim always immediately extinguished.
There are no errors.
It's hard to run it.
He can also go off for no reason.
Battery voltage is good. Charging too good. No voltage drops after pressing the trim. Bolt is sparge plug. The entire fuel system checked and efficient. As the engine turns off at this point injectors are switched off - pump is running and gives pressure.


Has anyone had a chance?

Have you load tested the battery? Had one a while back with good voltage and cranked motor fine but it ran like crap. Ran fine on the second battery so I load tested battery 1 and it failed miserably.....shows how sensitive these motors are to bad batteries.

Attempts were 2 batteries.
My impression of the damaged wiring harness remote control
or computer PCM

The motor I just mentioned ran fine on only the good battery. With the switch on both batteries it would not run either. Sounds like you need to find a short to ground in your situation.
