Have a Tahoe Q5I with a TKS 190 Mercruiser. Alarm buzzer is not working, changed out the alarm with a new alarm and still not working. Disconnected the sending and grounded and alarm went off, so power is good to alarm. Just not sounding when connected to harness runoff to engine. Any help would be appreciated in location of sensors on engine and trouble shooting. 2 week turn around at local dealer trying to avoid. Alarm worked previously fine. Just went to start boat and nothing. Thanks.
