What is the correct wiring method when connecting 2 batteries to an 250 H.P. evenrude outboard motor using an Attwood 14230-3 four position switch.

It should be a short circuit or a bad relay. Good luck.

If I remember correctly, it does not matter as they are just one way switches. That is why the new one is not color coded.

Could be broken wire in loom,or bad connection in loom plug or faulty ign switch which is very unlikely

Broken wire in loom,white wire,bad connection in loom plug,if it switches off with kill switch,then it points to ign switch

Bypass solenoid,put jumper from pos on batt to starter motor,but could be so many things,faulty battery cables,broken wire in loom,worn starter brushes,faulty solenoid ,start in gear switch or ignition switch

it is either a wire broke or the the starter solionde is broken check with volt meter at starter + and - if it shows up voltage its the brushes in the starter motor

Ok there are 2 ways todo this ,, the first is the easiest but not the cleanest..

First ..
1.) connect 8 guage wire from postive battery terminal to (2 port fuse holder)..
2.) from each of the fuse in the holder connect to the positive lead of each bulb (which should be in the bulb holder and in the headlamps or fogs or whatever).
3.) connect negative to a bolt on cars body.. Lamps will come on..
4.) remove positive from battery terminal..
5.) connect to your spst switch (what ever kind of switch u are using.)
6.) mount switch inside car,
7.) connect wire from other lead of switch to battery terminal..(pos)
Switch the lamps on and off using the switch..

Second method..

you will need
2 4-pin relays
8 guage wire
tester

1.) remove connectors from both head lamps
2.) turn on head lamps and test to see which is positive on each
3.) bridge this wire to the Com on the relay .. (1 head lamp to 1 relay)
connect positve wire from battery termial to relay (each relay seperate wire)
connect negative wire from cars body to relay (each relay seperate wire)
4.) connect Out from relay to Positive on Halogen bulb
6.) connect negative from bulb to cars body

now the lamps will come on and off with the head lamp switch..

Alternatively you can connect the fuse holder to the battery, and connect a switch to that and then that to the positive in on the relay..

Sorry I dont have any diagrams didnt have the time to draw one,, answered this quickly this morning before work..

if it is 24v. then you need to connect 2 battery in parallel. since the battery is only 12v.
if one battery is shoing red and the other is sohwing green, that means you are using 12v only, not the 24v.
connetion as follow:
positve of battery 1 to the motor, the negative of battery 1 to postive of battery 2. the negative of battery 2 to the motor.
