I have a 2001 nitro bass boat an i am replaceing my 12v tolling motor w. a 24v. i installed the 2d battery and am ready to connect the wires. There are 2 positive wires, 1 states "battery a" other states "battery b" and there is 1 negative. How do i connect the wires to the battery and will i need a short pig tail for the remaining connection?

Try to trace all wires and see if the metal part is still intact. Do not turn it on or allow electricity to pass yet! If wire metal intact, get some good quality black electrical tape and carefully tape all the exposed metal. When done, test system.
To prevent problem, use moth balls, fabric softener sheets, or pine sol soaked on cloths to deter mice & rats. If possible, use old- fashion mouse or rat traps with peanut butter to kill intruders to your boat. If you agressively eliminate them, the problem will be solved, but you may have to periodically repeat the trap use.

Dont have the manual in front of me...recollect that there's two types of warnings. The pulsating warning is oil (starts with 30 minutes of oil left) or the fuel filter (or sperator, something like that) may have water in it. Running outboard with cover off, is a little black box that would have a red light lit if that's the case. If oil full & no red light, may be oil injection system...would also check to make sure lines aren't pinched, etc. Mine has been specific to oil the two times its gone off.

The full non-pulsating is engine overheat. Not sure beyond that.

Not much, but hopefully gets you going.

Can't possibly know without check things with a meter. However, you should always use a GFCI receptacle when working with power equipment outdoors.

sound like either voltage drop or hi resistance from cables... if you test 24v at the plug then resistance is the problem and may have to rewire to a 6ga wire to carry the load, pretty simple just hook the new cable to the old one and SLOWLY pull it thru, help may be required because you dont want to loose it half way.....hope this helps...GL
