Look for loose connections, corroded connections, broken wires or partially broken wires. Don't forget the ground side. You need to start at the main ground, usually on the engine
block, follow that through whatever connections all the way to your electric
panel. Do the same with the positive side.
#1 of fixing stuff, always try the obvious and easy stuff first. I would bet 75% that it's a wiring problem. With 200 amp hour battery that is in a reasonable state of charge a normal sized bilge pump
will NOT pull enough power from your system to drop the voltage enough to cause problems with other loads. Now if you have really cheap
, funky LEDs then maybe something weird is going on but even that seems like a low probability.
So before you go spending money
and time on capacitors, regulators or whiz-bang whatzits check the wires. Don't forget sometimes it isn't obvious just glancing at them. You may have to pull and wiggle, loosen and tighten.
OR, if you know how to use a volt meter then test at various points in the system as you cycle the pump on and off and see if you find a noticeable voltage drop somewhere.
