I have 1999 43 Tiara with 3196 Cats that have been have the same Intermitant Gauge issue for a few years. I will check all the plugs and it is still happening. Now the Tack and Gauge clust does not work. It will come alive dueing the start circuit, bet once you let off the start button it looses power. The engine stays running and runns fine. Is there a relay for this gauge cluster?
Thank you for any help

A friend of my was telling some thing like that was going on on his Riviera a littler smaller , powered with twin C9 , I went to the boat and had not luck , because was difficult to trace an intermittent lost of power . Finally the day come in which the port engine and the display will not do anything , the key sw was not receiving power , but this was be coming from a type of protection , a black electronic box inside the console toward the left side . I have little diagram about the connection to it , I realized that the electronic section that control the port side was damage. I connected the port engine key sw to the same output where the starboard engine was connected , and bang , there it was . My friend order one of this box , the problem was solve .

You're probably right in saying that the multimetre isnt quick enough to pick up such a quick change in current but we will try hooking it up to the quad gauge. On the other hand, we did get a hold of some wiring diagrams and couldn't locate any relays on it. Would they be installed as an extra option by the boat manufacturer?? If so any ideas on their location?

Thanks for the reply,
We did think of that as a possible problem and set up a multimeter hooked up to the outgoing wires coming off the ignition switch which then supply the rest of the gauges. We then supplied an earth through the gear leads. Unfortunately, the voltmeter didn't show a loss of power when the gauges flickered. Is it possible that there is still a link through another plug or supply??
Thanks for the help,

I have twin 3196 660hp (approximately 1997) Marine Cats in my 48 foot Riviera. Since about 2 years ago, the Monitoring system and associated gauges for the port engine on the flybridge have been intermittently losing power, however immediately powering up again going through the usual start up sequence. Until early last year this was only an annoying problem that had no affect whatsoever on the motors function, but has since begun to shut the engine down ( a problem when you're trying to berth). It is interesting to note that this will only happen around every 10 reboots and will still allow it to restart immediately after. Having called Cat here in Australia with no luck, I thought the forum might give me some ideas. We have attempted to clean (what seems to us to be) every possibly related connection with no luck at all in solving the problem.
Looking foward to some suggestions,
