Mercruiser 6.2L engine alarm problem
Seems that James is clueless also.
"James" wrote in message link.net... I don't think so. The similarity between a 2002 merc i/o and your outboards ends somewhere around the fact that they both use gas. My first guess would be that he has the same alarm setup merc used for years. A collection of sensors is tied to an alarm. Nothing to do with the fuel control computer. If that is the case then he needs to determine is an alarm sensor is malfunctioning or if one of his gauges is not working. Probably safe to say he has oil pressure or he would have had some other nasty symptoms by now. Overheating is the other possibility. The correct test is to remove the sensor, hang it in a pot of water with a continuity or ohm meter on it and a thermometer it and raise the temp until it trips. Of course the shop would simply stick another sensor in and if that didn't work you'd get charged for it anyway. "Short Wave Sportfishing" wrote in message ...

Sometimes a tone code is generated to indicate the trouble area. Jim Yes, I've been through the owners manual *very* carefully, and no, there are no tone codes. It would be nice if they'd give you some indication but that doesn't seem to be the case. Apparently factory service technicians can tap into the ECM (Engine Control Module) and get more data. My ETECS have a system which indicates a "code" - this light blinks so many times it means this, etc. Sadly, you still have to get to the ECM to find out which sensor or thingymajigger is FUBAR. I wonder if those ecm readers that NAPA and Auto Zone sells might tell you what's what. |
