One for the gear heads.... or maybe a stupid question...
I have the motor and transom assembly removed from my boat... I wanted to know if there was a way to test some of the electrical systems (ie, bilge pump, trim tabs, engine hatch, newly installed lighting, etc) without engine or transom assembly in the boat. Not sure where my ground will come from or how to complete the circuit. I have easy access to all right now and want to make sure everything is working before I install motor. I should probably know this but just want to make sure before I blow out any wiring.
Thanks
Thanks

When the engine is installed, there is a battery cable going from neg on the battery to the engine block - most commonly a motor mount bracket or accessory bracket. As Cole mentioned, just establish a pos and neg with the battery using jumpers with alligator clips. Just be careful to make sure it is a positive wire that you are hooking up to the pos on the battery, and not a ground. Don't want to see you fry anything.

Not a stupid question!! Often times the fuse panels are powered by and grounded through the engine harness. So yes, unless the harness is connected to the other part of the harness on the engine, than nothing will work!! What you could do is run a separate ground (10 gauge) up to the helm to a grounding block. Run another wire from the grounds on your fuse panels to to the block. I don't believe there is anything wrong with having extra grounds. Then testing is simple, run a jumper lead from the positve side of the battery to the positive side of the fuse panel and everything will work!!
