battery inline fuses

got a 50hp 2stroke.got the two leads on the starting battery no inline fuses for these leads. got two other sets of leads on the same battery (for ff,bilge,lights,12v,radio,horn) and both have an inline fuse. what size fuse should be in there? my starting battery seems to be losing juice. the other day fishing for about 4hrs. my fish finder went dead. how do i check for what's the cause?

Re: battery inline fuses

Battery could be at the end of its life. You really should have a start battery and another one for accessories with a battery switch that you can isolate the starting battery and cut in the accessories battery to start if need be.

Re: battery inline fuses

Is your charger hooked up to all the batteries?

Re: battery inline fuses

Hook your motor up to a set of earmuffs and the garden hose and run to make sure your motor is charging the batteries. If you have a charging problem and are running a fish finder and live well that could be causing your low battery condition.

Battery switch is a cheap investment, easy to hook up and will keep low batteries from drawing down good ones.

Re: battery inline fuses

Yep run with the switch set to all batteries and start with the starting battery only unless it goes south, then you can use the other ones.

Re: battery inline fuses

sonar depth finders are real battery drainers. I drift fish and like the sonar on all te time. It can get you in to trouble, dead battery or not enough to kick over the motor.

I run dual batteries with transfer switch. Unless you wire a disconnect for the alternator, don't change the switch while engine is running (sometimes it will blow out your diodes).

Never run the bilge pump to feed thru the switch, run that direct to a battery, with a separate high rating in-line fuse. You only want to protect the bilge from a direct short, not motor over current.
