Main Message Board / Oil Pressure Alarm
« on: February 09, 2003, 05:14:02 PM »
The oil pressure alarm does not sound when the key it turned on.  My boat is a MKII #1383 with the Universal 35HP motor.  This problem has been intermittent for some time but now has gone hard not working.
 
 A. The red oil pressure alarm light comes on and then goes off when the engine is started.  The means to me the alarm sensing unit is AOK.
 
 B. I replaced the alarm unit with the loudest one Radio Shack had – know no oil pressure is bad news.
 
 C. I measured the voltage across the alarm when the motor was not running with the key turned on and found it was less than 4Volts.  The label on the alarm takes more than 4.2 Volts to work.  I would have assumed this would be closer to 12V.
 
 D. Unlike to water temp alarm, which just grounds the negative side of the alarm to activate it, the oil pressure alarm is some how involved with the lift pump and the pre-heat circuit.  Does anybody know:
 
 1. How the circuit works?   I gather it is to shut off the pre-heat and the lift pump once the engine has oil pressure.
 
 2. Where the 10A circuit breaker should in the circuit is located. I can find the main 20A breaker but not the 10A breaker in this circuit.
 
 E. The Oil pressure is AOK when the engine is running – yes, I do have an oil pressure gauge.
 
 Questions:
 
 A. Do I need a special alarm unit that work with a lower voltages
 B. Could something else in the circuit be broken?
 
 Thank you for your help.

Main Message Board / Water in the bilge
« on: July 04, 2002, 03:14:28 PM »
After an extensive search (using paper and then water-soluble markers) for where the salt water was coming from into my bilge, I finally tracked it down.  It is coming through around the aft most keel bolt.   Has anybody had the same problem?  If so, how did you go about fixing it?     Thank you all..

Main Message Board / New position for the instruments
« on: June 28, 2002, 03:43:45 PM »
Like most Catalinas, my instruments are mounted on the pedestal guard where neither the driver nor the crew can see them.  I am looking to move them forward to the top of the cabin at the front edge of the companionway – so they can be seen by all.    Does anybody have any experience in doing this project?  If so what were the major problems and how were they solved?   As I see it the most puzzling problem is how and where it run the wires so they are protected and not in the way.
 
 Thank you, Ray
