I have just serviced the engine (Hx cleaned & test, cleaned strainer, new raw impeller, manifold cover, tested thermostat, oil & filter, & fuel filters).
On the last two or three outings, motoring at 1500-2000 rpm, after 30-40 minutes, water temp gauge shows ~165F, alarm buzzer starts an intermittent and periodic crackle. On the last outing, after about 40 minutes, water temp alarm sounded, water temp gauge still shows ~165F.
I ran through the CatalinaDirect, test/confirm gauge (substituting BRN with YEL wire according to my boat and universal documentation) through step 3. Step 4 suggests sending unit may be defective.
I am left wondering, has my sender (to gauge) gone bad, has my switch (to alarm) gone bad, and/or do I have an un-invited switch to buzzer ground.
On my next outing, given crackle or water temp alarm I will remove the wire connection to the switch hoping to confirm/discover that after 40 minutes running there is an un-invited ground with the brown wire.
Any other ideas, tests, or suggestions?
TIA
