OMC SLOW startup alarm when running

1999 Johnson 90. My horn blows for 1 second and the lights in the tach count down while running the boat. This is just like when the ignition is first switched on, and is how the system shows that it is working.
It reminds me of the time I had a battery cable chafe through on a new truck. The momentary electrical short was just long enough to cut out the cruise control. I was lucky not to have a fire, since it was rubbing on a tranny cooler line, and burned a hole in the line (while towing a trailer with 7 racehorses!).
I was worried that I might have a problem with the VRO, but that checked out fine with the dealer when in for the 100 hour service.

99% of the time this is caused by a loose battery cable, pos or neg. Any interuption in the 12V feed to the motor will cause what you see happening. If the cables are tight and clean, next check the ignition switch. Good Luck, Just my .02

About the tach, not likely as the following conditions only will cause the horn to sound when operating properly.
1- initial power on, the horn sounds to tell you it is working.
3- fuel restriction (check eng light)
4- low oil
5- no oil

Tocobill, that's a good suggestion, and fits with my experience with the truck. I haven't had time to check the connections, but I think that it happened on both battery 2 and battery 1. However, the short could still be at the battery switch.
