MYSTERIOUS BEEPING

[venetrex]

I have a 2002 tige 21v riders edition with a mercruiser mag mpi towsports. I am getting a strange engine warning beep. It beeps for a few seconds when driving and then stops, then a minute later beeps and stops. All gauges ook okay. Temp is okay, oil pressure okay, batt okay. Any ideas on where to start????

Check your connections to the battery again. Mine did this twice and freaked me out, thinking I had an issue. Same deal where everything else was perfect except for the warning beep. I checked the connection to the battery and it was just a little loose. No issues since. Good luck.

You may want to check the connections at your starter also.

Conn at starter are okay, BAtt too, however, there are a few wires at the battery that I always get confused whether they are grds or + connections. Any leads on this??? 2 brown wires. Anyone got a pic of their battery?

My brown wire went to the bilge.

Brown usually goes to the bilge pump. When you get them right, zip tie those suckers together so there is no guessing where they go.

How old is your boat and does it beep twice above a certain RPM range? If it does this periodically every time you're above 2500 RPMs, it might be your fuel pressure regulator. That happened to me last year. There's a thread on this somewhere and if your Mercruiser is more than 8 years old, it probably is due for replacement. The only way to know for sure is to have the code checked by a service technician.

This is true also a fuel pump (low pressure) starting to go could give him the same beep. The pump would be priming off and on instead of keeping constant flow. If the high pressure pump starts to go it would be running bad, if at all.

Mine just started beeping at higher RPMs (2500+). It ran just fine, but I backed it off just as a precaution and had it checked out. It will gradually deteriorate. The fuel pump was just fine. The fuel pressure regulator is jiust a membrane that will deteriorate, especially if there's ethanol in your fuel.

My fue pump was changed 2 years ago, it does it under all RPM's. Even at idle.. I haven't had a chance to mess with it again, but I will on sat. Too much work for me this week.

I am going to chk all connections and such. I found a site to purchase an adapter to be able to scan the mercruiser computer for $199.00. I believe that's a deal.

How can you tell which it is? And other than a beep, what are the symptoms when it starts to deteriorate or fail?

Where is the site and how did the tool work for you?
