replacing clock on P31-2 electrical panel
« on: July 17, 2021, 10:12:08 PM »
I know it's a simple solution by just disconnecting it and sticking another clock of sorts over it, but I'm wondering if anyone has found a nice clock to wire in that can replace the old existing TIMEWATCH that's connected to the system with something more digital LED that use's less than the 0.05amps the existing one uses. It was actually this clock that drained my AGMs this spring after the batteries were charged by my marina, but left connected with the battery switch in the OFF position thinking that was suffice, but the clock is always connected, at least mine is. The most I've managed is to connect it to the RADIO breaker and it blinks all night, but still at 0.03amps. Thanks in advance for any advice or suggestions.

My P 323 has an hour meter but no clock. It is now on its 4th, this time a Hobbs, it required enlarging the eng. panel about an 1/8”, I used a file. Leaving the eng key on on mine discharges the battery through the alternator and racks up more hrs. On meter. Anyone have a simple fix for that?

Install an oil pressure safety switch.  These are normally not present on diesel engines.  Then wire the hour meter through its NO contacts.  This will only run the hour meter when there's oil pressure.
