Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

Yeah I need some spares now. I take it having empty sockets on the 7way connector is not an issue?

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

Well I put the whole system in myself...just didn’t do it right lol. But I suppose you’re right. Just have to pray that I really did fix it. Will know tomorrow.

Troubleshooting NMEA 2000 and the troubles with NMEA 200

I think I found the culprit. A third Maretron field connector that I forgot about, on the Precision 9 compass, that fits through a cutout in the wood bracket. It was cross threaded onto the compass...

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

System has been running for two hours at anchor, no errors and bus at 12%.

One time it faulted and I took out a cluster of T’s/drops and it started up fine. Put them back in and it started up...

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

Dan I don’t know for sure but 13.xx I’m fairly certain.

Yes I’m getting fast packet errors and Rx errors but no TX errors. Also interestingly the “bus load” pops up sporadically to 99.9% which...

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

Ok this is still a problem. Here's what I have on the network. All B&G/Simrad/Navico, from end to end:

Masthead anemometer (network powered)
Speed/depth transducer (network powered)
Electronic...

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

Well I did something else. The network faulted and refused to transmit data despite cycling it half a dozen times; I removed a cluster of T’/drops (plotter, GPS, rudder); the network booted fine; put...

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

I forgot to mention that it faulted again without any heat from the engine. But I'll proceed with caution if I clean the connector...I don't want to buy and run another mast backbone cable lol

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

OK I'm now suspecting the masthead connection. The stick was down for a year with the simnet cable dangling exposed. I did not clean the female sockets before reconnecting in the rush to get...

Troubleshooting NMEA 2000 and the troubles with NMEA 200

It’s a fairly small network. Only loads are the two mfd’s, three sensors (wind, speed/depth, and rudder feedback) and AIS antenna. If it were a power issue I would not expect it to work fine for...

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

The two mfd’s (which powered by the network) are getting power but no data. Also, this faults after a period of time, and *seems* heat related. I’m leaving the instruments on indefinitely right now...

Re: Troubleshooting NMEA 2000 and the troubles with NMEA 200

Dan,

I have a plotter, two mfd’s, and a vhf with built in AIS and an AP. When the network faults, the plotter shows nothing external on the network device list, the mfd’s go blank with no data,...

Troubleshooting NMEA 2000 and the troubles with NMEA 200

So I have an intermittent fault in my NMEA 2000 network and it is driving me crazy on two fronts.

Firstly, tracking it down is proving to be stupidly time consuming. It appears to be heat related....
