Radio Accessory Wire Hooked Up To Positive Battery?

[thedukeryan]

My battery has been draining over night and I am trying to diagnose what may be pulling power. Shortly before I started having issues I installed a new Pioneer CD player. I have it hooked directly to the battery and spliced the accessory switch in with the positive. Could this be what may be draining the battery? The only other changes that I have made is that I replaced the starter & solenoid's going to the trim pump. If its not the radio, starter or bad solenoids draining it is there any easy way to track the leak down? The battery is almost new and tested good. I also have a deep cycle that didn't test good but didn't test bad either. Would a deep cycle battery on its way out be a possible cause? The boat is a 1990 Wellcraft 233 Eclipse with a 5.7L Mercruiser. I am guessing the alternator is good since the boat runs fine after jumping and charges the battery back up enough to start once it has been running.

My bet is that your radio is draining your battery. May need to put it on a seperate switch. I had the exact same problem

The radio worked for say 5-6 days no problem. If its as simple as hooking it up to a switch then that's a easy fix. With that said did you notice the problem right after installing your radio or was it something that happened over time? The reason I ask is because it didn't do it right away. One other thing... Thinking back I really noticed the problem the same day I installed a new starter. My guess is that it has to be either the starter or the radio. Any chance a bad connection on the starter could drain juice? Right now I have the battery hooled up without the radio. Guess I will see how it looks tomorrow...

Great choice to pull the radio to check. that may point to the radio if it is it.

The other thing you said was I have it hooked directly to the battery and spliced the accessory switch in with the positive. did you connect both the power and accessory (memory) straight to the battery?

A loose connection to the starter could cause you problem with starting, but unlikely with draining the battery, unless you bent one of the wires around and it may be hitting the block.

Also, you said the deep cell is going out, are they connected together when not in use? if so, then that could be killing the battery as well.
