Hi,
Fairline Phantom 43 with 2xTAMD74EDCs. My port batteries (port eng + domestic) were end of life: was having trouble getting the engine started off it (often had to link to starboard) and topping up electrolytes a few weeks ago didn't help.
Swapped both batteries out for new ones today and had a go starting the engines from downstairs helm. Voltage looked good and both started fine, but the "active station" light was flashing as was the port diagnostic indicator. Port RPM stuck at 1000, unresponsive to throttle (+unable to select neutral) and diagnostic gave a fault code of 2.7 (potentiometer/wiring). After playing about a bit (flybridge controls seemed ok if I went active there) I cleared the error and downstairs appeared to behave itself again (no flashing, could select neutral + responding to throttle).
Is this kind of issue common after replacing both batteries, or do I have a potential problem building?
I had the shore power + all switches off when changing the batteries but wondering if I missed a step (some kind of other isolation) and maybe tickled something when changing the wiring over.
Now I think about it, what order should you replace wiring on a pair of batts? I went +ve -ve on one , then +ve -ve on the other... now wondering if it should have been both +ve then both -ve
