Re: Battery Drains While Boat Sits

try unplugging the big red plug at the engine. this should take all of the ignition out of the equation.

have you disconnected your accessories??..fish finder etc..??

What do I do after unplugging the big red plug? Do I connect the battery and check for a power drain or use the test light to test something?

Re: Battery Drains While Boat Sits

I would re-check what you did already...everything before the big red plug. Basically, if you thought that one of your ignition components were doing something funky, you are taking all of that out of the equation.. if you go through all the checks again and find that nothing is drainig then you know that its on the other side of the plug.

keep in mind, the big red wire from the battery runs to the engine as well as the black. if you use your test light you will see 12 volts or the light will go on across the two as if you were at the battery. your last few posts about the starter coil didnt sound right becasue the coil engages when you turn the key..and tthe starter engages after that turning the engine, so there is no way that it was causung anything.

from your battery you should have a wire to the engine and then a smaller wire to feed your accessories, bilge, radio etc.. if your bilge is quite you may not hear it and it still could be on..or if it has a float it too could be keeping it on. If you have a radio that displays time it is taking battery power. so again go through all of it

if you cant find it..try installing a battery switch that you can turn off when you are done using the boat. this will ensure nothing is running. you can also hotwire the bilge pump to run independant in the event you get water in the boat..if you dont oull the drain plug.

Thanks Riscardina, I'll retest with the big red plug unplugged.

The only accessories I have are lights, fish finder, and bilge. The bilge is wired separately and not connected, the fish finder and the lights are also wired separately and not connected.

Is it normal to have the Inline Fuse connection going to the fuse and the power pack?

Re: Battery Drains While Boat Sits

ok so if all of what you mentioned is disconnected then by unplugging the big red plug you essentially take out the ignition. that said, with the battery connected it should not be draining down.

once you see that its not then start connecting the accessories..again see if it starts drainng anything...if not then connect the red plug..if it does then its somewhere in the ignition system.

keep in mind batteries do slowy discharge over time..so make sure it fully charged so you dont mistakenly think something is drainig you when its just the battery doing what it does.

yes..that is to protect you on the engine side. if your starter gets jacked up or something shorts out there it will knock the fuse out and hopefully prevent things from blowing or burning up

Re: Battery Drains While Boat Sits

Tested with the big red plug unplugged.

I connected the negative battery cable to the negative battery terminal and the test light to the positive terminal. Then I...

touched the positive battery cable --> result light
touched the solenoid terminal where the red wire connects --> result light
touched the solenoid terminal where the cable connects to the starter --> result light

Disconnected the inline fuse
touched the positive battery cable --> result light
touched the solenoid terminal where the red wire connects --> result light
touched the solenoid terminal where the cable connects to the starter --> result light

disconnected the cable leading to the starter
touched the positive battery cable --> result light
touched the solenoid terminal where the red wire connects --> result light
touched the solenoid terminal where the cable connects to the starter --> result NO LIGHT

These are the results I got last night and unplugging the big red plug didn't do anything different.

Did I do the test correctly?

Yes but it will completely discharge in less than 12 hours. It did it with the starter battery and a deep cycle engine, both fully charged.

hard to say but llets think about this... if you conect the battery terminals...and not connect the other small red wire that goes to the light, etc.. then at the engine between the black and red you should see a light becasue its no different than being at the battery. so that ok but doesnt tell you anything other than the wire is intact.
by taking the fuse at the engine out you should see no light from one side of the fuse holder to black. you should see light from the other side of fuse holder to black..this is the side that comes from the battery.
you will see light at the solenoid becasue its on the power side of the battery terminals. the smaller posts on the starter should see nothing..(this only sees power when the key is turned)
curious..for giggles..when the connections are all made up as they were before..is anything warm to the touch?? or do you hear any humming or anything like that??

I don't know about being warm to the touch, I haven't tried. I don't hear a humming.

However....the small connections on the solenoid do light up when touched. I tried it with and without the fuse connected.

Re: Battery Drains While Boat Sits

do you have a meter?.. one that you could set to AMPS? its the best way to test a load to see if there is draw.. the test light only proves voltage is there and if you dont know electricity that well it can get confusing. for instance..a closed switch wont show a light..an open one will (example the posts on the solenid, if engaged will show no light, once it drop out it will show a light..) sounds odd right?..but thats how electricity works.

Im going to check my wiring diagram..ill be back

Re: Battery Drains While Boat Sits

I do have a multimeter, it is not digital but I think it would do the trick. I think I used it once a long time ago.

Re: Battery Drains While Boat Sits

ok..first, the 2 large posts on the solenoid should get you a light..this means solenoid is not engaged. this is correct.
the 2 small posts should not get you a light..
the inline fuse is connected to one side of the battery so one side will get light the other should not once you disconnect the fuse.

secondly, disconect the red wire at the bbattery and touch one side of the meter to the wire and the other to the battrey terminal.(your meter is between the wire and the battrey) .set the meter to amps (DC) and if your meter allows set it to 10 or so amps..if you dont get a reading then set the amps lower if your meter has a lower setting..if you get nothing then you are not drawing power...but if your meter doesnt go low enough you may not be able to see it without a digital one..

you might try this with the big red plug unplugged first...then test...then re attche plug and check again.. any changes will tell you where if anything is happening

Re: Battery Drains While Boat Sits

This is the Multitester I have. I'm not sure it will do the job. I set it to the "mA 50" setting and it lit up, buried the needle and now won't do anything, I think I killed it.

Re: Battery Drains While Boat Sits

that meter doesnt do amps..it does mA is (milli amps)..so anything over and you blow it,,,

it has a fuse in it so you may be ok to replace it..

you need something like this..

notice the left side says 20A and then next to it mA?.. its different..you dont need anything this high tech but definitely something close that does A.amps

Re: Battery Drains While Boat Sits

Does the flywheel or rectifier feel warm to touch after being connected for a hour or so?
