Starter issue on a Z1 2010 with PCM 5.7L Excalibur 343

[Ben_Deeluxe]

Hello Tigé owners,
I have a 2010 Z1 with the PCM 5.7L Excalibur 343 engine in France!
During my last ride, when starting the engine, I turned the ignition key, the starter started to work but the engine would not start. Then nothing happened, and when I turned the ignition key again, nothing happened.
When I switch on the ignition, the battery voltage is displayed at 0V on the dashboard. I checked the battery voltage directly and it was 12.8V. I checked the various fuses and everything was OK. The circuit breaker also works during an ohmmeter test.
Do you know why the battery display is at 0V on the dashboard and the starter won't start?
Is there any security that can do this?
Thank you for your help, because I don't know what to do!

Sounds like the battery, but let's go through the basics:

1. Disconnect and clean the battery terminals. Reconnect and see what happens. This has the added benefit of resetting the computer systems, so they go back to their defaults.
2. If that doesn't help, then get the battery (batteries) checked outside the boat.

Hope this helps, and have a good one,
Mike

Hi Mike,
Thank you. I check the battery outside and it's OK with the good level of charge.
The issue isn't the battery. Other ideas ? Please

Check the voltage at the starter

Ben,

Was the battery under a decent load when you checked the voltage? I've seen many batteries that had a failed cell show good voltage when no load is applied, then drop to less than 10v when a load is applied. Also, if you've removed the battery, you might just reinstall it (or if you feel brave just use a set of jumper cables to connect the battery to the boat, and see what happens when you try to start the engine.

First, turn the key into the On position and check the voltage. If that's looking good, then attempt to crank the engine (you don't have to start it, just crank it for a second). Don't attempt to watch the voltage during the start sequence, the system may actually shut down any systems that aren't used in the start sequence. So use a voltmeter to monitor the voltage.

If the battery voltage is acceptable, then start checking the wiring, starting at the battery. Check for loose/dirty grounds, corrosion on terminals, etc.

HTH, and have a good one,
Mike

Hello,

I checked the battery and recharged it. It's good with a voltage of 12.6V.
I re-installed it on the boat and I have a voltage of 12.6V at the starter terminals.
I've also checked all the fuses and relays above the engine (ignition/starter) and it's full OK.
When I put the key in the ignition position, I don't get the usual beep and the battery voltage is displayed at 0V on the dash.

Is it possible to have a problem with the throttle?
It is in the neutral position, but do you know what indication there is if you try to start the engine if the lever is not in neutral?
I'm lost and beginning to despair !
Thank you for your help

Ben,

I think the next thing I'd check would be the ignition switch itself. It sounds like the switch isn't powering up the engine/instrumentation system, although it is obviously powering up the display itself. The neutral switch should be able to be worked around by using the neutral throttle button to advance the throttle out of the center position.

A bad throttle will cause a no start.

I have zero experience with TBW in a boat, but is the neutral bypass (what I call it in my '96 LaBrisa, where you pull the button and the tranny is disengaged and the neutral switch is overridden) different in a TBW system?
