call graham @ delta re: in-water stuffing box repacking, or learn how to do it myself in the water.

current working 12v circuits

engines and gearboxes, open issues

✅ 1: Port ignition switch not firing the starter

I replaced both start relays and one of the relay harness/plug ends which was very corroded inside.

2: Starboard stop solenoid + relay needs to be rewired

This solenoid seems to be broken. I ordered a new one. I also am considering just changing to a cable, which is recommended by some online due to these weird relay setups and solenoid failures.

3: Both RPM gauges need to be hooked back up

These should be a small wire on each alternator. Out of two small wires, one is the signal wire and the other is this RPM driver. Either on a spade or ring terminal.

4: temp and pressure on strbrd side hooked up

✅starboard transmission stop switch needs rewired

But why was it cut out of the loop? Do I even need this? I removed both instead of fixing the second one. I really do not see a need for this feature for me personally.

Starboard oil pressure sensor not working

All sensors need testing so I understand how to troubleshoot later. Need to know the baseline values and where to probe to get them.

Starboard v-belt is worn

✅ Replaced Aug 2024!

Starboard harmonic balancer seems wobbly

✅ Shakedown cruise Aug 2024 it did fine during two 4-hour trips, so I guess it's just visual!

120v for house, open issues

Outback inverter is not connected to shore power due to poor wiring conditions.

Heavy gauge cables can be connected directly to gel 8d to power galley outlets and the remote panel does work, but it really should be done properly with an off switch and a pretty large fuse!

12v for house, open issues

85CHB38 electrical panel notes from Jeff Small

current dead circuits

12v for engines, open issues

✅ can I connect alternators directly to the 8D gel battery?

Yes, simply connect the alternator B+ wire with enough amperage gauge to a 3/8" stud and extend from there into the selector switch.

✅ can I start both engines from one battery?

Yes, but it is important to not start them up at the same time, because the battery should be given a minute to recharge from the first alternator before cranking it again at engine 2. This has not been an issue but just seems like good practice.

does the glendinning box work?

Currently I am able to control engines 1 & 2 individually, and so I do not want to test this system until after the Poulsbo Aug 9-11 cruise. Last time I was testing it is when the system became unable to disengage, so I want to take care around testing it once the engines start/stop and electrical connections are all solid.

notes on the synchronizer from glendinning rep

Synchronizer clutch as described in the manual Section K. Synchronizer clutch is slipping. PROBLEM / SYMPTOM: Additional symptoms: Description of Operation: POSSIBLE PROBLEM RECOMMENDED ACTIONS Lack of bridge cable overtravel-terminal eye on the control cable from helm station control is incorrectly adjusted. AFTER TURNING SYNCHRONIZER OFF, SLAVE ENGINE CONTROL HANDLE IS NOT ABLE TO CONTROL SLAVE ENGINE SPEED. None When Synchronizer control switch is turned OFF, manual control of the slave engine must be reestablished. This is normally accomplished by moving the slave engine control handle back the idle speed position, allowing the bridge control cable to be reconnected mechanically to the engine control cable. Readjust the terminal eye on the bridge control cable at the Synchronizer to achieve proper o travel see Section J of the manual. NOTE: 1) If the overtravel adjustment is slightly OFF, slave engine control may be regained t very rapidly pulling the slave engine handle back to the idle position. On a 2-station ba try regaining manual control at the other helm station. 2) The overtravel adjustment can be thrown off by improper adjustment of the stop so at the control head
