Eskape New Battery... No Power
« on: June 29, 2018, 06:38:21 PM »
I installed a new battery on my MOkAI but I am not getting any power at the starter.
Before I start tearing apart the starter assembly does anyone have a schematic or curent diagram of cable pinouts?
Thanks in advance  >:(

Cycle all your connectors, on the engine, and at the hull sections. There have been many of these with connection issues. Wiggle them all. On the starter, there are three wires connected to the solenoid. Two big wires are power in and out, and small wire to energize the solenoid. Use a screwdriver to jump that small wire to the large post below it, if the starter doesn't spin then you probably have a bad solenoid.

Found a loose positive terminal at the solenoid. Once that was tightened I got a brief green ignition light flash while connecting the larger connector. Before I take apart all the wiring which of the seven pin(s) should have a 12 volt output? ???

Here's the pinout from my 2015, your's should be the same.

Hey Woodennickle,
Always check your grounds first.  Just had a boat die last week.  First time in many years.  You guessed it.  Ground.  Just a thought

Agreed, George, grounds are always my first check too. These connectors on the ES-kape have had lots of problems with bad pins though, I've seen several that had corroded and/or had poor crimps.  :(

I also installed a new battery on my Es-Kape and started having problems. I thought it was a faulty connector because the two halves go together too easily, without friction. I ended up sending the control box and wiring harness off to Mokai. I've been away for a week and will follow up with them on Monday. I was initially getting the green LED power light but only 3.4 volts on Pin 1 where there should have been 12 volts. After a few attempts at cleaning, the green LED doesn't even light.

A friend who knows a lot more about electronics than me sent me this link. This seems right up Tom's alley.

Good find on the info link. I think that might have been put together by some of my customers that are with MIT, they've done some autonomous projects with the ES-kape and converted one or two to electric drive. Pretty cool stuff. The connectors are a problem with these though, I've had to go through several troubleshooting bad connections.

By "die" do you mean that it abruptly stopped or that it wouldn't start?

Had a couple of boats out for a shakedown run.  First boat was good.  Second ran fine up the river and for some fishing.  Then the kill switch stopped working.  Had to shut down with the key.  Later  when tried to restart - nothing at all.  Obviously electric problem.  I was only a hundred yards above the ramp so just paddled in.  Next morning found a bolt on the floor that held the regulator and several grounds.  One minute fix.

Thanks to all for the help. I definitely had a few wires loose - some on my Mokai too. The battery post on the solenoid was loose and one of the pins from the paired wires coming out of the ignition was not fully seated. Now I now have power and ground coming out of the pinouts and continuity from the wall plug to the ignition wire and solenoid switch. Ignition light goes on but ONLY FOR A SECOND OR TWO before the circuit breaker blows any suggestions on how to isolate the short?

 I disconnected the cable connecting the steering servos and the circuit doesn't blow. So no I can start the Mokai, just can't steer. >:(
