How can I check that the other battery is charging as well?

That will not work in this situation as it will not answer your questions for example.
1/ Are BOTH batteries wired to the charge circuit.
&
2/ Are both batteries isolated from each other.
&
3/ It will only tell you the voltage of the battery that the particular unit is running off and with a long run of cable the reading will not be accurate due to the voltage drop or "losses" within the cable
If in any doubt before you try to rewire anything consult a competent marine auto electrician, a fire on your boat is the last thing you want especially while out at sea!!

it will work for him. His question is if the battery that's running the electronics is charging or not. There will be some voltage drop true, so it might read 14.3 volts versus 14.5 at the battery for example, but it will tell him if the battery running the fishfinder is being charged or not. The people who build the fishfinder and write the manual must know something about marine electonics no?
